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)…

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…

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…

Riverine wetlands along the Mississippi River provide habitats for migratory waterfowl and many other ecosystem services. However, frequent flooding along the Mississippi River caused flood control infrastructure such as levees and dams to be built to minimize flooding impacts. This strategy caused wetland habitat reduction and altered the flood frequency of the system. In June…

The UGA team will review existing plans, tools, and data, including the Roadway Vulnerability Assessment GIS model, to identify additional data for integration into “compound” flooding data that considers: (a) sunny day flooding, (b) storm surge flooding, and (c) select design rainfall events for the CORE MPO metropolitan planning area. Rainfall-runoff data will consist of…

Compound inundation models have been developed and applied around the world in rich-data regions. However, there are many places, like in the Caribbean, where compound hydrodynamics has not been studied in full detail. For example, Cuba is next to the Florida Panhandle, and their corresponding inundation hydrodynamics could be very similar or not during the…

The Tybee Island Natural Infrastructure Master Plan provides recommendations on integrated nature-based features to help the island better absorb and recover from more frequent storms and flooding caused by rising, warming seas. Developed in collaboration with the University of Georgia and numerous local, state, and federal partners, the plan assesses flood risks and adaptation solutions,…

Compound flooding is defined as a flood event caused by the combined effects of flood drivers. Numerical modeling of compound flood events allows for the design of risk-mitigation strategies but requires simulations of several flooding scenarios. Current modeling techniques cannot simulate multiple processes simultaneously and lose accuracy when modeling compound flood events. This project aims…

The purpose of this study is to support the District in evaluating the impact of septic infrastructure on surface water quality in streams within the 15-county metro Atlanta area. Specifically, this study will employ time-sensitive sampling techniques to assess the effects of rain events on interactions between septic system characteristics (e.g., system age and density)…
