What's new in GMS 10.8

Keep your license current by paying annual maintenance to continue receiving all available updates, releases, and technical support. New licenses include maintenance for 1 full year.

GMS 10.8 offers a new interface to the HydroGeoSphere (HGS) model. HGS is a powerful, fully-integrated hydrologic modeling platform used to model overland/surface water flow and variably saturated groundwater flow. Unprecedented environmental challenges and complex, unpredictable water systems require an integrated, physics-based approach to hydrologic modeling. HGS offers tools to improve understanding of hydrologic systems for enhanced decision support, increase operational efficiency, and promote interdisciplinary collaboration between groundwater and surface water teams.
