GMS:HydroGeoSphere

From XMS Wiki
Jump to navigationJump to search

HydroGeoSphere (HGS) is a three-dimensional control-volume finite element simulator created by 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.

Graphical Interface

The GMS interface for HydroGeoSphere contains multiple components. These components include:

  • An unstructured grid (UGrid)
  • HGS coverages
  • HGS simulation, including the Simulation Control
