Dr. Zhonglong Zhang is a Senior Scientist with over 27 years of experience in the development and application of watershed, water quality, and ecological models. Since 2002 he has conducted modeling research and development within the Water Quality and Contaminant Modeling Branch of the Engineer Research and Development Center (ERDC). He has been the lead developer and primary author of plug-in water quality modules (nutrients, sediment diagenesis, solids, contaminants, and mercury species). These modules have been developed for a variety of hydrologic and hydraulic models and have been integrated into HEC-RAS, HEC-ResSim, HEC-HMS, AdH, and SRH-2D at various levels. He has been a co-developer of the riparian vegetation simulation module for HEC-RAS and SRH-1D and of the latest CE-QUAL-W2 model upgrade and enhancement. In addition, he has applied these models in support of a variety of military installation, ecosystem restoration, environmental impact statement, and TMDL studies. He has applied the SWAT model to the Mississippi River basin, the HEC-RAS water quality model to the Missouri River, Minnesota River, Calleguas Creek and Patuxent River; and the HEC-RAS and CE-QUAL-W2 models for the Columbia River System Operations.
Dr. Zhang obtained a PhD in Biosystems Engineering at Clemson University. He has been called in for providing expert review by the USACE Districts and taught graduate and undergraduate courses as an adjunct faculty member. He has authored/co-authored over 60 technical publications, including journal articles and software user documentation. He works at one of LimnoTech’s other staff locations in Davis, California.
