By integrating instrumentation dynamics effects of breaking have been quantitatively estimated. Contaminated sediments can cause serious water quality problems. Fundamental understanding of velocity bottom boundary layer and sediment profile under wave-current interactions is critical. I am developing an in-situ underwater camera with velocity profilers to examine resuspension, deposition, and particle size distribution. The ultimate goal is to develop a physically sound model for the prediction of sediment transport.
Wetlands have widely recognized functions of water quality improvement.
I am studying the effects of submerged and emergent vegetation on surface water and sediment processes. With detailed spatial and temporal measurements of water flow and sediments, a dynamic wetland model that can predict water quality and flow will be developed.
