WDPM: The Wetland DEM Ponding Model
The current version has been developed to make the program faster and easier to
use. The WDPM code was ported from Fortran to C, and a graphical user interface
was been added by Oluwaseun Sharomi and Ray Spiteri of the Department of Computer
Science at the University of Saskatchewan. The parallel processing now uses
The purpose of the WDPM is to model the spatial distribution of runoff water on the Canadian Prairies. Because of its recent post-glacial history, the Canadian Prairies do not have a conventional drainage system. When excess water runs off the landscape, generally due to snow melt in the spring, it may trapped in surface depressions ranging in size from puddles to permanent wetlands, and may cause local flooding. If the depressions are full of water, they may connect.
The WDPM was developed to model the spatial distribution of water over a Prairie landscape, as represented by a Digital Elevation Model (DEM). Originally, the purpose of the program was to determine the fractions of Prairie basins contributing flows to streams, as these change dynamically with the storage of water in the depressions. However, the model has also been used to demonstrate the extent of flooding on Prairie landscapes, which may be useful for operational purposes.
