Abstract The HYDRUS codes have become standard tools for addressing many soil, agricultural, environmental, and hydrological problems requiring the evaluation of various subsurface physical, chemical, biological processes. There are now thousands users worldwide, with applications models appearing in peer‐reviewed literature. In this manuscript, we provide an overview capabilities most recent Version 5 HYDRUS, focusing primarily on features implemented since 2016. We briefly describe model its nonstandard specialized add‐on modules that significantly expand software packages. include HPx, UNSATCHEM, Wetland, Furrow, PFAS, COSMIC, DPU, SLOPE Cube, Particle Tracking. Recent developments Package MODFLOW also described, along additional incorporated into graphical user interface supporting HYDRUS. Also discussed new or improved options to simulate fate transport environmental isotopes, multi‐cropping systems, compensated root water uptake, hydraulic redistribution within rootzone, which will be upcoming modules. Another objective is review selected models, such as evaluations irrigation, low‐impact development (LID), managed aquifer recharge (MAR) schemes.

Abstract. Freezing-induced groundwater-level decline is widely observed in regions with a shallow water table, but many existing studies on freezing-induced groundwater migration do not account for water-level fluctuations. Here, by combining detailed field observations of liquid soil content and fluctuations at site the Ordos Plateau, China, numerical modeling, we showed that interaction dynamics was controlled wintertime atmospheric conditions topographically driven lateral inflow. With an initial table depth 120 cm inflow rate 1.03 mm d−1, freezing thawing-induced level are well reproduced. By calculating budget groundwater, mean upward flux loss 1.46 d−1 93 d, while recharge as high 3.94 32 d. These results could be useful local resources management when encountering seasonally frozen soils future two- or three-dimensional transient flow semi-arid regions. comparing models under series conditions, found magnitude decreases increases We also fixed-head lower boundary condition would overestimate shallow. Therefore, accurate characterization critical to quantifying contribution hydrological ecological processes cold
