Advances in HydroGeoSphere Over the Last Decade

A recording of Aquanty's May 2026 webinar "Advances in HydroGeoSphere Over the Last Decade" where we examine the evolution of HydroGeoSphere (HGS) from its origins as an ambitious integrated hydrologic modelling experiment to a widely trusted, industry-leading platform advancing groundwater and surface water simulation. Much has changed with HydroGeoSphere since it's initial launch in 2002, especially since it's commercialization under the support and management of Aquanty since 2012. What started as an ambitious experiment to build fully integrated hydrologic simulations that bridged the gap between groundwater and surface water flows has become an industry-leading, widely trusted platform setting the standard for innovation in the field of hydrological modelling. In this webinar Dr. Hyoun-Tae Hwang (Director of HydroGeoSphere) provides a comprehensive retrospective tracing the evolution, milestones, and innovations defining the last decade of HydroGeoSphere development. Join us to learn more about the transformation of HGS, including examples and case studies highlighting: 1) The impact of parallelized and high-performance computing 2) Advanced in physics and numerical methods 3) New features, workflows and applications (such as particle tracking, source zone identification, tunnelling, water management practices, hydraulic mixing cells and dynamic meshing/topography) 4) Innovations and advancements in computational performance HydroGeoSphere (HGS) is a three-dimensional control-volume finite element simulator which is designed to simulate the entire terrestrial portion of the hydrologic cycle. It uses a globally-implicit approach to simultaneously solve the 2D diffusive-wave equation for surface water flow and the 3D form of Richards’ equation for variably saturated groundwater flow. HGS also dynamically integrates key components of the hydrologic cycle such as evaporation from bare soil and water bodies, vegetation-dependent transpiration with root uptake, snowmelt and soil freeze/thaw.
