ABSTRACT
Zhonglong Zhang is a senior scientist at Badger Technical Services, Environmental Laboratory, U.S. Army Engineer Research and Development Center. In addition, he is an adjunct faculty member of the Civil and Environmental Engineering Department at both Mississippi State University and Jackson State University. Previously, he served as a principal environmental systems modeler with Concurrent Technologies Corporation in Bremerton, Washington, and as a project scientist and interim supervisor with the USEPA Center for Subsurface Modeling Support, Ada, Oklahoma. His PhD is from Clemson University. He has specialized in the development and application of mathematical models to watershed, river, reservoir, lake water quality problems. He has been involved in the development of a number of USACE watershed and water quality models in common usage. He was the lead developer of nutrient simulation modules (NSM) and contaminant transport, transformation, and fate (CTT&F) submodel for hydrologic and hydraulic models. He was the developer of a raster based landscape hydrology and chemical fate model. He developed new water quality and sediment diagenesis modules for CE-QUAL-W2 and supported the development of some multimedia transport/fate/risk assessment models for military installations. Recently his work has focused on the development of linked watershed (SWAT, HSPF) and riverine (HEC-RAS) modeling systems for total maximum daily load, biofuel development and environmental sustainability studies. He has also provided technical review and support of watershed, surface water, and groundwater models for FEMA, USACE Districts, and USEPA Regions.
