Hurricanes and tsunamis are both powerful natural phenomena that can cause widespread devastation. However, they originate from fundamentally different sources and are governed by distinct physical processes. A hurricane is a cyclonic storm system that forms over warm ocean waters, fueled by the evaporation and condensation of water vapor. A tsunami, on the other hand, is a series of waves caused by large-scale disturbances in the ocean, most commonly underwater earthquakes, but also volcanic eruptions, landslides, or even meteorite impacts. Understanding these differences is crucial for effective disaster preparedness and mitigation.
Accurate knowledge of the separate mechanisms that generate these events is vital for coastal communities. Recognizing the distinct characteristics allows for better prediction and tailored response strategies. Historically, confusion about the origins of coastal flooding has led to inadequate warning systems and increased vulnerability. Separating the dynamics of these natural hazards allows for improved scientific modeling, enhancing the accuracy of forecasting and enabling more effective evacuation plans.
While fundamentally different, both hurricanes and tsunamis can have cascading impacts that exacerbate the effects of the other in certain scenarios. For instance, the storm surge from a hurricane can weaken coastal defenses, making them more susceptible to damage from a subsequent tsunami. Furthermore, the debris and infrastructure damage caused by a hurricane can complicate tsunami evacuation efforts. Exploring these interconnections, while acknowledging the distinct origins of each phenomenon, is essential for a complete understanding of coastal hazards.
1. Different generating mechanisms
The contrasting mechanisms that generate hurricanes and tsunamis are fundamental to understanding their distinct behaviors and independent occurrence. Examining these differences is essential when addressing the question of how these two phenomena are related, as it clarifies why one does not directly cause the other, while also revealing how their impacts can sometimes overlap or compound.
-
Atmospheric Pressure and Convection vs. Seismic Displacement
Hurricanes are born from atmospheric instability over warm ocean waters. Low pressure systems draw in surrounding air, leading to evaporation and the formation of thunderstorms. The Coriolis effect causes the system to rotate, forming an organized cyclonic structure. In contrast, tsunamis are most often caused by the sudden vertical displacement of the seafloor during an earthquake. This displacement generates a series of waves that radiate outwards from the source. The disparate nature of these triggering events means that a hurricane cannot directly cause a tsunami, and vice versa.
-
Energy Source and Scale
The energy fueling a hurricane comes primarily from the latent heat released during the condensation of water vapor. This continuous energy input allows hurricanes to sustain themselves for days or even weeks, traversing thousands of miles. Tsunamis, however, are driven by the immense kinetic energy released during a seismic event. While a single earthquake can release far more total energy than a hurricane, this energy is initially concentrated over a smaller area and dissipates as the tsunami propagates across the ocean. The difference in energy source and scale influences the duration, speed, and spread of each phenomenon.
-
Wave Characteristics: Wind-Driven vs. Displacement-Driven
Hurricane waves are generated by the force of the wind on the ocean surface, creating relatively short-period waves that contribute to storm surge. The height of these waves is dependent on the wind speed and duration. Tsunami waves, in contrast, are displacement-driven, meaning they are generated by the entire water column being pushed upwards or downwards. These waves have extremely long wavelengths (often hundreds of kilometers) and periods (tens of minutes to hours), making them largely undetectable in the open ocean. The fundamental difference in wave characteristics explains why hurricanes cause localized flooding due to storm surge, while tsunamis can inundate coastal areas thousands of kilometers from their origin.
-
Predictability and Warning Systems
Due to their different generating mechanisms, hurricanes and tsunamis require separate prediction and warning systems. Hurricane forecasts rely on weather models that track atmospheric conditions, while tsunami warnings are based on seismic data and ocean buoy networks that detect changes in sea level. The lead time for a hurricane warning is typically days, allowing for extensive preparation. Tsunami warnings may only provide hours or even minutes of notice, depending on the distance from the earthquake epicenter. The divergent approaches to prediction and warning underscore the need to understand each phenomenon independently, even when considering potential interactions or compounded effects.
In summary, the distinct origins and energy sources of hurricanes and tsunamis dictate their individual characteristics and behaviors. While a hurricane cannot directly trigger a tsunami, the damage inflicted by a hurricane can compromise coastal defenses, increasing vulnerability to future tsunami events. Understanding the “Different generating mechanisms” is therefore crucial for comprehending the complexities of coastal hazard assessment and mitigation.
2. Independent event occurrences
The concept of “Independent event occurrences” is paramount in understanding the complexities of “how are hurricanes related to tsunamis explained”. While both are devastating natural disasters, they arise from distinct causes and often occur independently of each other. This independence impacts prediction, preparation, and mitigation strategies.
-
Geophysical Origin
Hurricanes are meteorological phenomena driven by atmospheric conditions, whereas tsunamis are geophysical events primarily resulting from seismic activity. The formation of a hurricane necessitates warm ocean waters, low atmospheric pressure, and specific wind patterns. Tsunamis, conversely, are triggered by underwater earthquakes, volcanic eruptions, or landslides that displace large volumes of water. The separate geophysical origins indicate that the occurrence of one does not directly trigger the other. For example, a hurricane striking the Gulf Coast of the United States has no direct impact on the likelihood of a tsunami occurring in the Pacific Ocean due to seismic activity along the Ring of Fire.
-
Temporal Correlation
The timing of hurricane and tsunami events underscores their independence. While it is possible for a hurricane and a tsunami to occur within a similar timeframe, these occurrences are coincidental rather than causally linked. Historical records show instances where coastal regions have been struck by a hurricane followed by a tsunami weeks or months later, but these are statistically independent events. For example, a region might experience a hurricane season followed by an unrelated earthquake that generates a tsunami. The absence of a consistent temporal relationship reinforces the understanding that these events are driven by separate mechanisms.
-
Spatial Relationship
Hurricanes and tsunamis affect different geographic regions based on their respective generating factors. Hurricanes are prevalent in tropical and subtropical regions with warm ocean waters, such as the Atlantic and Pacific hurricane belts. Tsunamis are more common in areas prone to seismic activity, particularly around the Pacific Ring of Fire. While both can impact coastal regions, the spatial distribution of these events varies significantly. Coastal areas on the eastern seaboard of the United States are more susceptible to hurricanes, while countries bordering the Pacific Ocean are at greater risk of tsunamis. The distinct spatial distribution further illustrates the independent nature of these hazards.
-
Predictive Modeling
The independent nature of hurricanes and tsunamis necessitates the use of separate predictive models and warning systems. Hurricane forecasting relies on weather models that analyze atmospheric pressure, wind patterns, and sea surface temperatures. Tsunami warnings are based on seismic data, sea-level monitoring, and inundation models. The absence of a direct causal link between these events means that information from hurricane models cannot be used to predict tsunamis, and vice versa. The development and deployment of independent predictive tools highlight the necessity of treating these hazards as separate entities.
In conclusion, the concept of “Independent event occurrences” serves as a cornerstone in understanding the distinct nature of hurricanes and tsunamis. While both can cause extensive damage to coastal regions, their separate origins, temporal correlations, spatial relationships, and predictive modeling approaches underscore their independence. Recognizing this independence is crucial for developing effective hazard mitigation strategies tailored to the specific risks posed by each type of event. The devastating 2004 Indian Ocean Tsunami, for instance, occurred independently of any hurricane activity and highlighted the need for comprehensive tsunami warning systems in vulnerable regions.
3. Storm surge vulnerabilities
Storm surge, a significant threat associated with hurricanes, directly influences coastal vulnerability, impacting the comprehensive understanding of how these storms relate to potential tsunami impacts. Hurricane-induced storm surge can weaken or destroy natural and man-made coastal defenses, such as dunes, mangroves, and seawalls. This degradation leaves coastal communities more susceptible to the destructive forces of tsunamis, even those of moderate intensity. The relationship is not causative, meaning a hurricane does not cause a tsunami. However, the damage inflicted by the storm surge creates conditions that amplify the potential consequences of a subsequent tsunami event. For instance, a hurricane that erodes a protective barrier island could increase the inland reach of a tsunami should one occur in the future. This is critical in how are hurricanes related to tsunamis explained.
Consider the scenario where a hurricane devastates a coastal region, severely damaging infrastructure, including hospitals and emergency services. If a tsunami were to strike this weakened area shortly thereafter, the pre-existing damage would significantly impede rescue efforts and exacerbate the humanitarian crisis. Evacuation routes could be blocked by debris from the hurricane, and communication networks might be disrupted, hindering the dissemination of tsunami warnings. Furthermore, salt water intrusion from the storm surge can contaminate freshwater sources, further complicating recovery efforts in the event of a subsequent tsunami. These combined factors underscore the importance of incorporating storm surge vulnerability assessments into comprehensive coastal risk management strategies. The storm surge increases existing vulnerabilities.
In summary, while hurricanes and tsunamis originate from distinct physical processes, the concept of storm surge vulnerabilities highlights a critical interrelationship. The damage caused by hurricane storm surge can drastically increase the susceptibility of coastal areas to tsunami impacts, complicating disaster response and prolonging recovery. Addressing this interconnected risk requires integrating storm surge assessments into tsunami preparedness plans and prioritizing the restoration and reinforcement of coastal defenses to mitigate the compounded effects of these natural hazards. Proactive measures reduce “Storm surge vulnerabilities” significantly enhance overall coastal resilience and offer a more accurate context within “how are hurricanes related to tsunamis explained”.
4. Coastal defense weakening
The degradation of coastal defenses by hurricanes plays a crucial role in understanding the potential relationship between these storms and tsunamis. While hurricanes do not cause tsunamis, the damage they inflict on protective barriers significantly increases the vulnerability of coastal regions to subsequent tsunami events. This weakening fundamentally alters how coastal areas respond to and recover from such disasters.
-
Erosion of Natural Barriers
Hurricanes generate powerful storm surges and waves that can erode natural coastal defenses such as sand dunes, barrier islands, and mangrove forests. These natural features dissipate wave energy and reduce the inland penetration of storm surges. When these defenses are eroded or destroyed by a hurricane, the coastline becomes more exposed to the full force of subsequent tsunami waves. For example, the erosion of barrier islands off the coast of Louisiana by hurricanes Katrina and Rita significantly increased the vulnerability of inland communities to future flooding events, including potential tsunamis.
-
Damage to Engineered Structures
Hurricanes can also damage or destroy engineered coastal defenses, such as seawalls, levees, and breakwaters. These structures are designed to protect coastal areas from wave action and flooding. When these structures are compromised by a hurricane, they lose their effectiveness, leaving coastal communities more vulnerable to inundation from both storm surges and tsunamis. The failure of levees in New Orleans during Hurricane Katrina demonstrated the devastating consequences of damaged engineered defenses, which would undoubtedly exacerbate the impact of a subsequent tsunami.
-
Sediment Transport and Coastal Morphology Changes
Hurricanes cause significant sediment transport, altering coastal morphology and potentially destabilizing coastal regions. The removal of sediment from beaches and coastal wetlands reduces their ability to absorb wave energy and protect inland areas. Changes in coastal morphology can also alter wave propagation patterns, potentially focusing tsunami energy on specific locations. For instance, the reshaping of coastlines during Hurricane Sandy resulted in increased erosion and flooding in some areas, highlighting the dynamic interplay between storms and coastal landscapes that could affect tsunami vulnerability.
-
Increased Inundation Extent
The cumulative effect of eroding natural barriers, damaging engineered structures, and altering coastal morphology is an increased extent of inundation during both hurricane storm surges and tsunami events. Coastal areas that were previously protected by natural or engineered defenses become more susceptible to flooding. This increased inundation extent poses a greater threat to coastal communities, increasing the risk of property damage, infrastructure failure, and loss of life. The compound effect of a hurricane weakening coastal defenses and a subsequent tsunami inundating a larger area underscores the interconnectedness of these hazards.
In conclusion, the “Coastal defense weakening” resulting from hurricanes is a critical factor in understanding how these events relate to potential tsunami impacts. While hurricanes and tsunamis are distinct phenomena, the damage inflicted by hurricanes on coastal defenses can significantly increase the vulnerability of coastal regions to tsunamis. This heightened vulnerability necessitates a comprehensive approach to coastal risk management that considers both the individual and combined effects of these natural hazards. Effective coastal zone management, resilient infrastructure, and community preparedness are essential to reduce the compounded risk posed by hurricanes and tsunamis.
5. Debris obstructs evacuation
Hurricanes generate substantial quantities of debris, ranging from building materials and vegetation to vehicles and household items. This debris field poses a significant impediment to effective evacuation procedures, particularly in the context of a subsequent tsunami threat. The relationship underscores a critical aspect of how these two distinct natural hazards can interact to amplify disaster consequences. A hurricane’s immediate aftermath often includes impassable roads, blocked emergency routes, and disabled communication networks, all of which severely hamper the timely movement of populations away from vulnerable coastal areas. The destruction wrought by Hurricane Katrina, for example, left entire neighborhoods in New Orleans inaccessible, rendering large-scale evacuations virtually impossible in the face of potential future threats, including tsunamis. The presence of widespread debris transforms evacuation from a logistical challenge into a potentially life-threatening ordeal.
The significance of debris obstructing evacuation lies in its capacity to negate early warning systems and well-laid evacuation plans. Even with adequate tsunami warning times, the presence of debris-choked roads and damaged infrastructure can prevent residents from reaching safe zones. Furthermore, the psychological impact of a recent hurricane can lead to evacuation fatigue, causing individuals to delay or forgo subsequent evacuations, even in the face of imminent danger. In such circumstances, the combined effects of physical obstacles and psychological hesitations can dramatically increase the number of casualties resulting from a tsunami. Effective disaster management strategies must, therefore, prioritize rapid debris removal and the establishment of clear, accessible evacuation routes following a hurricane to mitigate the heightened tsunami risk.
In conclusion, the intersection of hurricane-generated debris and tsunami evacuation highlights a critical vulnerability in coastal disaster preparedness. Addressing the challenge of debris obstruction requires a multi-faceted approach, including pre-emptive infrastructure reinforcement, rapid post-hurricane debris clearance operations, and public education campaigns that emphasize the importance of heeding evacuation orders, even in the aftermath of a previous disaster. A comprehensive understanding of how debris obstructs evacuation, is crucial for developing resilient coastal communities capable of effectively responding to the combined threats posed by hurricanes and tsunamis.
6. Compounded disaster impacts
The confluence of hurricane and tsunami events, while distinct in origin, can lead to compounded disaster impacts that far exceed the consequences of either event occurring in isolation. Understanding these amplified effects is critical to comprehending the full scope of “how are hurricanes related to tsunamis explained,” requiring a comprehensive analysis of their interactions.
-
Infrastructure Overload and Systemic Failure
A hurricane can severely compromise critical infrastructure, including power grids, communication networks, transportation systems, and healthcare facilities. The added stress of a subsequent tsunami can overwhelm already strained resources, leading to systemic failure. Hospitals operating on emergency power may be unable to handle a surge of tsunami-related casualties. Damaged roads can impede the delivery of aid and evacuation efforts, exacerbating the humanitarian crisis. The combined impact significantly hinders recovery efforts and prolongs the suffering of affected populations. The Fukushima Daiichi nuclear disaster, triggered by a tsunami following an earthquake, exemplifies the cascading failures that can occur when a natural disaster strikes an already vulnerable system.
-
Economic Devastation and Disrupted Supply Chains
Hurricanes can cause widespread economic damage, disrupting businesses, damaging property, and impacting agricultural production. A subsequent tsunami can compound these losses, further devastating coastal communities and disrupting global supply chains. Ports damaged by a hurricane may be unable to receive or dispatch goods, leading to shortages and price increases. The destruction of agricultural land by saltwater inundation can result in long-term food insecurity. The cumulative economic impact can be devastating, particularly for developing nations that lack the resources to rebuild and recover. The 2010 Haiti earthquake, followed by subsequent hurricane seasons, highlighted the challenges of recovery in the face of repeated disasters.
-
Environmental Degradation and Ecosystem Damage
Hurricanes generate storm surges and high winds that can damage coastal ecosystems, including wetlands, coral reefs, and mangrove forests. A subsequent tsunami can exacerbate this environmental degradation, causing widespread habitat destruction and biodiversity loss. Saltwater inundation from a tsunami can contaminate freshwater resources, impacting both human populations and wildlife. The combined effect can have long-term consequences for coastal ecosystems, reducing their ability to provide essential services such as storm protection and fisheries support. The damage to mangrove forests in Southeast Asia caused by the 2004 Indian Ocean tsunami significantly reduced coastal protection against subsequent storms.
-
Psychological Trauma and Community Disruption
Experiencing a hurricane can cause significant psychological trauma, leading to anxiety, depression, and post-traumatic stress disorder (PTSD). A subsequent tsunami can compound this trauma, increasing the risk of mental health problems and disrupting community cohesion. The loss of homes, livelihoods, and loved ones can have a devastating impact on individuals and families. The combined stressors of multiple disasters can overwhelm coping mechanisms and lead to long-term psychological distress. Effective disaster response must address both the immediate physical needs of affected populations and their long-term mental health needs. Studies following Hurricane Katrina revealed a significant increase in mental health problems among survivors, highlighting the lasting psychological impact of compounded disasters.
The examination of these facets underscores that the synergistic effects of hurricanes and tsunamis demand comprehensive risk assessment and mitigation strategies. Understanding “how are hurricanes related to tsunamis explained” necessitates acknowledging that the potential impact extends beyond the sum of individual events. Developing robust early warning systems, resilient infrastructure, and community preparedness programs is vital to minimizing the compounded consequences of these devastating natural hazards.
7. Separate warning systems
The existence of distinct warning systems for hurricanes and tsunamis highlights a fundamental understanding of their separate origins and propagation characteristics. This separation is not merely an administrative convenience but a critical necessity dictated by the differing physical processes governing each phenomenon. Examining the rationale behind these “Separate warning systems” is essential to a comprehensive explanation of “how are hurricanes related to tsunamis explained,” clarifying why integrated warnings, while seemingly efficient, would be inherently less effective and potentially dangerous.
-
Data Acquisition and Analysis Divergence
Hurricane warning systems rely primarily on atmospheric data gathered from satellites, weather balloons, and aircraft. Sophisticated numerical models ingest this data to forecast storm tracks, intensity, and landfall locations. Tsunami warning systems, conversely, depend on seismic data from seismographs to detect underwater earthquakes and on sea-level monitoring buoys to detect the passage of tsunami waves. The data streams and analytical methods are entirely different. A single system attempting to process both atmospheric and seismic data would be inefficient and prone to errors, delaying critical warning dissemination. The distinct nature of the data requirements mandates separate infrastructures for effective threat assessment.
-
Propagation Characteristics and Warning Lead Times
Hurricanes develop over days or weeks, allowing for relatively long warning lead timestypically ranging from hours to days before landfall. Tsunami waves, on the other hand, can travel across entire oceans in a matter of hours, drastically reducing the available warning time, especially for communities near the earthquake epicenter. The disparate speeds of propagation necessitate different warning protocols and dissemination strategies. Attempting to integrate hurricane and tsunami warnings into a single system would inevitably compromise the timeliness and specificity of each warning, reducing their effectiveness. For example, a delayed tsunami warning due to a complex, integrated system could have catastrophic consequences for coastal communities.
-
Dissemination Strategies and Public Response
Hurricane warnings are typically disseminated through mass media outlets, emergency alert systems, and local authorities. Public response often involves evacuation from low-lying areas, securing property, and stocking up on essential supplies. Tsunami warnings require a more rapid and targeted dissemination approach, often relying on sirens, text messages, and direct communication with coastal communities. The urgency and specificity of tsunami warnings demand a distinct communication infrastructure and public education campaigns. Combining hurricane and tsunami warnings into a single, generic message could lead to confusion and a delayed response, potentially undermining the effectiveness of both warnings. A tailored approach is necessary to ensure an appropriate and timely response to each threat.
-
False Alarm Mitigation and Public Trust
Frequent false alarms can erode public trust in warning systems, leading to complacency and a reduced willingness to heed future warnings. Integrating hurricane and tsunami warnings into a single system could increase the likelihood of false alarms, particularly if one system is more prone to errors than the other. Maintaining separate warning systems allows for more precise threat assessment and a reduced risk of issuing unnecessary alerts, thereby preserving public trust and ensuring that people take warnings seriously when they are issued. The reliability and accuracy of individual systems are crucial for maintaining public confidence and ensuring effective responses to future disasters.
In summation, the “Separate warning systems” for hurricanes and tsunamis are not arbitrary but are based on fundamental differences in their generating mechanisms, propagation characteristics, and required response protocols. A unified system would inevitably compromise the speed, accuracy, and specificity of both warnings, potentially jeopardizing public safety. These distinct approaches are essential to explaining “how are hurricanes related to tsunamis explained,” because, although both cause coastal damage, combining them at the warning level would be detrimental to saving lives.
8. Mitigation strategy divergence
Mitigation strategies for hurricanes and tsunamis exhibit significant divergence, reflecting their distinct origins, impact zones, and time scales. This divergence is not merely a matter of logistical preference; it is a fundamental consequence of the disparate physical processes governing these natural hazards. Consequently, understanding this “Mitigation strategy divergence” is a crucial component of “how are hurricanes related to tsunamis explained,” illuminating why a one-size-fits-all approach is not only ineffective but potentially dangerous. Hurricane mitigation focuses on structural reinforcement, flood control, and evacuation planning tailored to predictable storm paths and surge zones. Conversely, tsunami mitigation prioritizes early warning systems, vertical evacuation structures, and coastal reforestation, strategies designed to minimize the impact of rapidly approaching, unpredictable wave surges. This difference necessitates specialized expertise, resource allocation, and community engagement.
Consider the Netherlands, a nation renowned for its comprehensive flood defense systems. While these systems offer robust protection against storm surges from North Sea storms (akin to hurricane effects), they would be insufficient against a direct tsunami strike. The long wavelengths and immense energy of a tsunami require different defense mechanisms, such as robust seawalls designed to withstand the force of a massive wave and strategically located evacuation routes leading to higher ground. Similarly, coastal communities in Japan, while well-prepared for tsunamis, must also contend with the threat of typhoons (the Western Pacific equivalent of hurricanes). The mitigation measures employed against typhoons, such as building codes that emphasize wind resistance, are not necessarily effective against the inundation caused by a tsunami. Therefore, even in regions vulnerable to both hazards, distinct mitigation strategies are essential.
In conclusion, the “Mitigation strategy divergence” between hurricanes and tsunamis arises from fundamental differences in their nature. Effective coastal hazard management requires a nuanced understanding of these differences and the implementation of tailored mitigation measures. Ignoring this divergence can lead to misallocation of resources, inadequate protection, and increased vulnerability to these devastating natural events. Therefore, acknowledging this divergence is an essential step in comprehensively explaining “how are hurricanes related to tsunamis explained”, promoting more effective and targeted disaster preparedness efforts.
9. Research focused areas
The relationship between hurricanes and tsunamis, while not causative, presents several critical “Research focused areas” that directly enhance the understanding of “how are hurricanes related to tsunamis explained”. One significant area involves the study of coastal geomorphology and sediment transport. Hurricanes, with their intense storm surges and wave action, can dramatically alter coastlines, eroding natural barriers like dunes and barrier islands. Subsequent research focuses on how these hurricane-induced changes affect tsunami inundation zones. Scientists employ numerical models and remote sensing techniques to analyze pre- and post-hurricane coastal topography, assessing the amplified risks of tsunami impacts in vulnerable areas. This research is vital for refining tsunami evacuation maps and coastal zone management strategies. For instance, studies following Hurricane Katrina demonstrated that the loss of coastal wetlands significantly increased flood depths during subsequent storm events, underscoring the importance of understanding the long-term effects of hurricane damage on coastal resilience to other hazards, including tsunamis.
Another critical research area centers on the interplay between climate change, hurricane intensity, and sea-level rise on overall coastal vulnerability. Climate models project an increase in the frequency and intensity of extreme weather events, including hurricanes. Rising sea levels exacerbate storm surge flooding and increase the potential for saltwater intrusion, weakening infrastructure and degrading coastal ecosystems. Research explores how these long-term trends compound the vulnerability of coastal regions to both hurricanes and tsunamis. Scientists are investigating the effectiveness of various mitigation strategies, such as the construction of artificial reefs and the restoration of mangrove forests, in reducing the combined risks from these hazards. The practical significance of this research is evident in the development of climate-resilient coastal infrastructure and adaptation plans that account for the complex interactions between multiple environmental stressors.
Furthermore, interdisciplinary research efforts are crucial for improving disaster preparedness and response. These efforts bring together meteorologists, seismologists, engineers, social scientists, and emergency management professionals to develop more effective warning systems, evacuation procedures, and community resilience programs. Research focuses on improving communication strategies to ensure that warnings reach vulnerable populations in a timely and understandable manner. Studies also examine the psychological and social impacts of multiple disasters, informing the development of mental health support services and community-based recovery initiatives. These integrated approaches aim to minimize the combined risks posed by hurricanes and tsunamis, building more resilient coastal communities in the face of increasing environmental challenges.
