HydroGeoSphere - Integrated Hydrologic Models
HydroGeoSphere (HGS) is the world’s most powerful integrated hydrologic modeling platform. HGS is a three-dimensional control-volume finite element simulator which is designed 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.
HGS dynamically integrates key components of the hydrologic cycles and can incorporate land surface processes such as evaporation from bare soil, transpiration with evolving vegetation, unsaturated flow, flow in porous and/or discrete fractured media, and reactive solute and thermal energy transport within the overall hydrogeosphere. Macro pores, fractures, and tile drains can be incorporated discretely or using a dual-porosity, dual permeability formulation. The model can also simulate winter hydrological processes such as snow accumulation/melting and pore-water freezing/thawing.
The HydroGeoSphere platform has been parallelized to utilize high performance computing facilities and to address challenging scientific and engineering problems such as the analysis of climate change impacts on water resources at the watershed, basin, and continental scales.
“Simulating natural processes using mathematics is a fairly difficult job, and these guys have done a very good job of it. It's a fantastic technology, actually. It's ahead of its time. It’s very helpful in solving complex problems and will save a lot of money”
— Dr. Ranjeet Nagare, Groundwater Scientist - WorleyParsons
