HydroGeoSphere (HGS) is a three-dimensional control-volume finite element simulator created by [https://www.aquanty.com/ Aquanty]. HGS can be used to model the entire terrestrial portion of the hydrologic cycle. It uses a globally-implicit approach to simultaneously solve the 2D diffusive-wave equation for overland/surface water flow and the 3D form of Richards’ equation for variably saturated groundwater flow. GMS allows multiple HGS simulations to exist in a single GMS project. | HydroGeoSphere (HGS) is a three-dimensional control-volume finite element simulator created by [https://www.aquanty.com/ Aquanty].

A 3D UGrid of the project area is required. While the project can contain multiple UGrids, only one UGrid can be attached to each HGS simulation. The desired UGrid will need to be linked to the HGS simulation. | |||
