Zhen-Gang (Jeff) Ji, PhD, DES, PE, is an oceanographer with the United States Bureau of Ocean Energy Management and is also an adjunct professor at the Catholic University of America. He has more than 20 years of professional experience in surface water modeling and model development. His expertise includes hydrodynamics, wind wave, eutrophication, toxic process, and sediment transport.
""As scientists specializing in the area of developing and evaluating land surface models for earth system models, we found this comprehensive book extraordinarily refreshing and resourceful.... This textbook by Professor Zhen-Gang Ji is a long overdue and welcome addition to the water resources and water quality modelling and analysis literature."" <—Nigel W.T. Quinn and Zong-Liang Yang, Environmental Modelling and Software, February 2019 ""With the updated second edition, we will continue to refer to Zhen-Gang Ji's book to better understand details about 'niche' disciplines of the aquatic sciences and transport and fate processes in different types of waterbodies. The second edition of this book will be a welcome addition to university/agency libraries and the personal libraries of ASLO members who are either actively engaged in modeling or describe themselves simply as a scientist/engineer who is 'not a modeler.' <—Andrew Stoddard, Limnology and Oceanography Bulletin, May 2018
