Jeffrey H. Hwang, Ph.D.

Dr. Hwang has over 28 years of research and field experience in water resources engineering, including hydrology, surface and groundwater modeling, statistical analysis, GIS applications, water resources planning and management, and software development.

Dr. Hwang has developed numerous procedures and computer models to solve water resources problems, including the Wasteload Allocation Model (WLAM), the Rainfall-Runoff-Route-Rootzone model (R4) for large watersheds and groundwater basins, the recharge basin performance evaluation procedure and computer program used in the Chino Basin Master Recharge study, a mountain watershed simulation model, an Uncertainty Analysis program for stream water quality simulation (SNSIME), a goodness-of-fit test program for the ten most common probability distribution models (GOF), mathematical and computer simulation models for estimating the oxygen transfer rates of steady and non-steady wastewater treatment operations, and others. In addition, Dr. Hwang has extensive experience with several simulation models that are available in the public domain, including the US EPA’s surface water quality simulation models (QUAL2E, SWMM, BASIN, SWAT, and Visual Plumes) and the USGS’s groundwater simulation models (MODFLOW, MODPATH, and others).

Dr. Hwang received a B.S. in Mineral and Petroleum Engineering from Seoul National University in 1972, an M.S. in Water Resources Engineering from the University of California at Los Angeles in 1979, and a Ph.D. in Water Resources Engineering from the University of California at Los Angeles in 1983. He is a member of the American Water Resources Association, the National Ground Water Association, and Groundwater.
