Research Areas

Flood Hazards

We study flood hazards induced by extreme events such as hurricanes, heavy rainfall, and dam or levee failure. We aim to better understand evolving hazards associated with flooding, motivated by the rapid growth of population and assets in low–lying areas, global warming, and sea level rise. Through hydrodynamic and wave numerical modeling, we specifically study storm surge and wave hazards under present and future climate conditions.

Flood Mitigation

Flood mitigation using natural and nature–based features (NNBF) is an active area of research in our group. Due to their ecosystem services and benefits, NNBF such as wetlands has gained significant attention among the public and decision makers. We have developed a suite of computational models to quantify the influence of vegetation on the mean flow, wave energy, and turbulence. We apply these models to real–life case studies to investigate the role of wetlands as natural buffers against inundation, storm surge, and waves.

Coastal Hydrodynamic

Dynamic processes in the nearshore region are generated by a number of different drivers such as tides, storm surge, and surface waves. Using theories, measurements, and numerical modeling, our group studies the influence of different driving forces and their interactions on nearshore processes. We specifically study wave-current interactions, wave setup, estuarine circulation, and residence time.

Sediment Transport

We study sediment transport in river-reservoir systems and coastal morphodynamics and their response to natural or man–made disturbances (e.g. flooding, storm surge and wave). We numerically study reservoir sedimentation, unsteady sediment transport, and flood–induced river morphology change. We implement phase-average and phase-resolving wave models to understand effects of extreme seas on coastal features such as beaches, dunes, and wetlands.
