Adaptive Hydraulics (AdH) is a modern, multi-dimensional modeling system for saturated and unsaturated groundwater, overland flow, three-dimensional Navier-Stokes flow, and two-dimensional or three-dimensional shallow water problems. Developed by the Coastal and Hydraulics Laboratory at the Engineer Research and Development Center in Vicksburg, MS, the 2-dimensional (2D) shallow water module of AdH was released to the public in September 2007.  

AdH has been used to model many different areas throughout the world. The models associated with projects at CHL are shown on the map. If you have an AdH model that you would like to add to the map, please contact us.     

AdH version 4.7.2 is now released. See the "Downloads" menu for the associated files. The ACE-IT version is now available on the App-Portal.

AdH input and output files are ASCII text by default and readable by anyone or any coding language.  However, CHL has worked with Aquaveo, LLC to develop the Surface Water Modeling System (SMS) as a graphical user interface that functions with the current release version of AdH.  This tool has free and paid options but all tools necessary for using it with AdH are freely available in the Community Version of SMS.
