Mapping Compound Inundation along Puerto Rico’s Coastal Watersheds: A Practical Approach

Due to recent compound flood events such as Hurricane Harvey (2017), Hurricane Florence 2018), and Hurricane Sally (2020), inundation studies have transitioned from single flood hazards toward multi-hazard flood modeling approaches. A compound flood is a flooding event that encompasses multiple flood hazards (e.g., precipitation, overland runoff, riverine flow, storm surge, waves, and astronomical tides)…

Floodplain Reconnection at Shawnee National Forest Oxbow

The degradation of the Big Muddy River watershed (Illinois, US), resulting from historical agricultural and mining practices and levees, has led to habitat loss and flooding problems in populated regions such as Cape Girardeau. The impact of river channel geometry on flood behavior has been extensively studied, focusing on how floodplain reconnection can enhance meandering…

Inland Litter Hydrodynamics: Characterizing the Litter Transport during Wet Weather Events in Communities

During wet weather events, the litter accumulated in communities, e.g., along the street gutter, can be transported by the surface runoff along the city streets and storm drainage system until it reaches outlets, which could be a river or the ocean in coastal communities. Despite this, most research on litter dynamics has occurred over the…

About the CITRA Lab

The Compound Inundation Team for Resilient Applications (CITRA) research group bridges the gap between academic research and practical application. Our team uses the latest technology to solve complex water resources problems covering inland and underground regions to coastal and estuarine locations. An essential component of any project is the dissemination of the results, thus CITRA engages the community and stakeholders by simplifying complex concepts into simple analogies.
