Collaborative Research: An Efficient Computational Approach for Wave & Surge Attenuation in Wetlands and Applications in Flood Risk Reduction
Continued climate change and sea level rise pose a major threat to coastal habitats and communities worldwide. The impact of sea level rise has resulted in increased coastal erosion and flooding. For example, owing to subsidence, sea level rise and human interventions, Mississippi River Delta and Louisiana coast lose one acre of wetland every 24 minutes, which accounts for 80% of the total annual loss of coastal wetlands in the continental United States. The chronic wetland loss in south Louisiana has considerably weakened the natural defense against catastrophic floods, such as Hurricanes Katrina and Rita. Over 1,500 people lost their lives and several major coastal populations were crippled for months after the hurricanes passed.
The goal of the proposed study is twofold: 1) to improve the theoretical understanding of resistance induced by flexible and rigid objects by developing an accurate and efficient computational method for modeling the interaction of free surface flow with flexible vegetation systems, and 2) to parameterize the complex process and up-scale our model result for engineering applications.
