Hydrodynamic models are computer-based programs designed to simulate processes and movements in water bodies. Scientists and policymakers use the robust information produced by hydrodynamic models to improve our understanding and develop policies for the protection and future management of water bodies. Current environmental issues in Lake Champlain that are or could be informed by hydrodynamic models include excess nutrients, changing temperature dynamics, flooding, harmful algae blooms, pathogens, contaminants, and invasive species. Existing hydrodynamic models are currently used to forecast flood risk and to determine how seasonal water current and nutrient dynamics affect the occurrence of harmful algae blooms, among other applications.

In Lake Champlain, hydrodynamic models have been developed and utilized for a variety of purposes. This document summarizes early modeling efforts focused on Lake Champlain and describes five hydrodynamic models used to describe the hydrodynamics of the lake.
