Joseph Hughes

Joseph Hughes is a hydrologist in the Earth Systems Modeling Branch and is currently working on MODFLOW enhancements.

Dr. Joseph Hughes is a hydrologist with the U.S. Geological Survey Integrated Modeling and Prediction Division in Reston, Virginia. He completed his B.S. and Ph.D. at the University of South Florida and his M.S. at the University of Michigan. Prior to working at the U.S. Geological Survey, Dr. Hughes worked for a number of consulting firms including DHI Water and Environment and Arcadis Geraghty and Miller. Dr. Hughes has extensive experience simulating surface water and ground water interactions, variably saturated groundwater flow, groundwater flow in variable-density environments, and surface water and ground water quality at local and regional spatial scales. Dr. Hughes specializes in the development of of numerical simulation codes to solve surface-water flow, groundwater flow, and advective-dispersive transport equations. He is a co-author of several numerical hydrologic codes including MODFLOW 6, a control-volume, finite-difference version of MODFLOW (MODFLOW-USG), the Sea Water Intrusion (SWI2) Package for MODFLOW, the Surface Water Routing (SWR1) Process for MODFLOW, and a multi-species version of the density-dependent groundwater flow and transport code SUTRA (SUTRA-MS). Dr. Hughes also specializes in the development of linear sub-space methods to solve simultaneous systems of equations.
