Integrated surface water-groundwater models (ISGMs) simulate surface water and groundwater systems within a single, cohesive numerical framework. These models dynamically represent interactions between surface water features, such as rivers, lakes, and wetlands, and the underlying groundwater system. This holistic approach offers a more accurate representation of the hydrologic cycle by capturing both water exchanges and the complex feedback mechanisms that influence key watershed functions and features.

ISGMs are essential tools for evaluating the cumulative effects of land use change, water withdrawals, climate variability, and engineered water management infrastructure on water availability and ecosystem health.

We specialize in the application of GSFLOW, a powerful, open-source modelling framework developed by the U.S. Geological Survey. Built on the trusted MODFLOW and PRMS model codes, GSFLOW allows us to simulate surface and groundwater systems together in one platform, helping our clients make informed, science-based decisions for sustainable water management across communities, industries, and natural environments.
