AdH Menu


AdH logo 1 resizedAdaptive 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 4.7.1 is now released. See the "Downloads" and "Documentation" menus for the associated files. The ACE-IT version is available on the App-Portal.

Uses of AdH

A range of modeling applications can be addressed with AdH, including:
  • Design of approach channel improvements
  • Guardwall porting design
  • Design of a fish passage structure through an existing spillway
  • Velocity field calculations during different stages of construction
  • Overall effects of sedimentation due to the proposed work.
  • Evaluating the effects of multiple projects constructed within a river reach to support objectives for both navigation and ecosystem restoration.
  • Salinity intrusion analysis in conjunction with system changes.
  • Impacts of navigation channel design changes on ship passage by supplying hydrodynamic results to the Ship Simulator.
  • Effects of vessel traffic on hydrodynamics, salinity, and sedimentation with the use of simulating vessel movement in the model.
  • Flood inundation by use of dynamic and continuous wetting/drying fronts.
