Agriculture is one of the most important sources for non-point source pollution due to the use of chemicals in plant and animal production. Many mathematical numerical models evaluating water flow and the fate and transport of these chemicals in the subsurface were developed over the last three or four decades. These models are now readily available and widely used. This presentation will first briefly review recent (and soon to be released) versions of the HYDRUS models widely used to model water flow, chemical movement, and heat transport through variably-saturated soils. I will discuss various specialized HYDRUS modules intended to simulate processes not available in the standard HYDRUS versions, such as the transport of multiple interacting solutes (including fumigants, surfactants, and PFAS), preferential flow, colloid-facilitated solute transport, cosmic ray neutron fluxes, and natural isotopes. These new modules include the DualPerm, C-Ride, HP1/2/3, Wetland, UnsatChem, Fumigant, Cosmic, Furrow, PFAS, DPU, Slope3, Particle Tracking, and many other modules. Finally, I will briefly review many recent applications of the Hydrus models, which include modeling of various irrigation practices, different contaminants, and different cropping systems. About the speaker: Dr. Jirka Šimůnek is a Professor and Hydrologist at the Department of Environmental Sciences of the University of California Riverside. He received an M.S. in Civil Engineering from the Czech Technical University, Prague, Czech Republic, and a Ph.D. in Water Management from the Czech Academy of Sciences, Prague. His expertise is in numerical modeling of subsurface water flow and solute transport processes, equilibrium and nonequilibrium chemical transport, multicomponent major ion chemistry, field-scale spatial variability, and inverse procedures for estimating the hydraulic properties of unsaturated porous media. He has authored and co-authored almost 400 peer-reviewed journal publications, over 30 book chapters, and three books. His h-index is 97 according to Goggle Scholar. His numerical HYDRUS models are used by thousands of scientists, students, and practitioners to model water flow, chemical movement, and heat transport through variably saturated soils. Dr. Šimůnek is a recipient of the Soil Science Society of America’s (SSSA) Don and Betty Kirkham Soil Physics Award, a Fellow of the American Geophysical Union (AGU), American Society of Agronomy (ASA), American Association for Advancement of Sciences (AAAS), and SSSA. He is a recipient of 2019 SSSA Soil Science Research Award and 2021 AGU Hydrological Sciences Award. Dr. Šimůnek is an Editor-in-Chief of the Journal of Hydrology, a past co-editor of the Vadose Zone Hydrology and Journal of Hydrology and Hydromechanics, and a former associate editor of the Journal of Hydrology, Water Resources Research, and Journal of Hydrological Sciences. |
