Interests include physics of sediment transport, fluid mechanics instrumentation, environmental hydraulics, fluvial hydraulics, and interactions between aquatic organisms and hydraulic processes.
Specific examples of past and current research include:
Fish passage design for warm water fish species.
Utilization of compost for erosion control on slopes.
Investigation of flow patterns in a large, shallow lake to determine advection of dissolved oxygen. Field measurements, numerical models, and a physical model were all employed.
Measurement of turbulence distributions in river meanders.
Assessment of watershed characteristics using digital elevation models (DEM's).
Experimental investigation of the effects of pipe inclination angle on the transport of suspended solids.
