Dr. Fang's research experience in water resources engineering includes assessing performance of sediment basins at highway construction sites, evaluation of scour potential of cohesive soils, estimation of volumetric and rate-based runoff coefficients using observed rainfall and runoff data, development of modified rational unit hydrograph, regional unit hydrograph and storm hyetograph development, rainfall loss estimation using non-linear programming, estimation of time parameters for Texas watersheds, synthesis of storm drainage design, and study of sediment transport in gravel-bed rivers.
His research experience in environmental hydrodynamic/ecological modeling includes one-dimensional lake water quality modeling (studying impacts of global warming on fish habitats in small lakes in the contiguous USA), two-dimensional reservoir water quality modeling (studies on three Texas reservoirs), three-dimensional computational hydraulics modeling using FLOW-3DÒ (specializing in free-surface flow simulations) and EFDC (Environmental Fluid Dynamics Code), and water quality monitoring in estuaries.
