Deva BoraDeva K. Borah, Ph.D., P.E., F.ASCE, Senior Engineer at the City of Chesapeake, Department of Public Works, Chesapeake, VA

Dr. Borah has over 40 years of experience in Civil, Environmental, and Agricultural Engineering as an engineer, researcher, and educator at government agencies, private organizations, and academic institutions. He developed and published five original models simulating hydrology, hydraulics and nonpoint-source pollution in watersheds, streams/rivers, estuaries, tidal bays, and shorelines. He applied those and other models in engineering projects solving real world problems. He also critically reviewed currently available prevalent watershed hydrologic and nonpoint-source pollution models, compared their mathematical bases and various other aspects, and published those in refereed journals.

Nigel Quinn is a Research Group Leader at Berkeley National Laboratory with a long history of working on salinity, selenium and other water resource and water quality issues in the San Joaquin Valley.  He has been associated with the Bureau of Reclamation for the past 30 years first working as lead hydrologist with the San Joaquin Valley Drainage Program in the late 1980’s , on selenium management issues an the Grasslands Bypass Project in the 1990’s and as technical chair of the Central Valley salinity Coalition from 2000 onward.

An expert on monitoring network design, flow and water quality monitoring – he has been a leader in the implementation of the concept of real-time water quality management.

Zhonglong Zhang, Ph.D., P.E., PH, Research Professor at Portland State University, Civil and Environmental Engineering Department

Dr. Zhang is a Research Professor of Civil and Environmental Engineering at Portland State University and a Senior Scientist at LimnoTech. He was an Adjunct Professor at Mississippi State University and Jackson State University in 2007 – 2016. He has 30 years of experience in wide ranging areas of watershed and water quality modeling. His research activities have focused on advancing watershed and water quality modeling. He has worked side‐by‐side with the U.S. Army Corps of Engineers team for the development of plug‐in water quality modules for a variety of hydrologic and hydraulic models. He is the primary author of a set of water quality modules that are currently coupled with HEC‐RAS, HEC‐ResSim, AdH, SRH‐2D. He is a co-developer of the riparian vegetation module in HEC‐RAS and the latest CE‐QUAL‐W2 V4.2. Additionally, he conducted 1D, 2D and 3D water quality and ecological modeling studies throughout the country to evaluate environmental impacts and water quality problems, and support ecosystem restoration projects. He was instrumental in leading a watershed modeling development and study to examine the transport and fate of nutrients in the whole Mississippi River Basin.

He has developed and lectured at water quality modeling workshops and short courses and provided review and technical support for USACE, EPA and FEMA. He has been an active participant in professional organizations and served on several committees for ASABE, ASCE, AWRA, WEF, and AIH.
