Model Description

English {{currentDetailLanguage}} English

Quoted from: https://research-groups.usask.ca/hydrology/modelling/wdpm.php 

      The Wetland DEM Ponding Model (WDPM) was developed by the Centre for Hydrology at the University of Saskatchewan to model the distribution of runoff water on the Canadian Prairies. The program was originally written in Fortran 95 by Kevin Shook in 2008. Because the program requires many thousands of iterations to converge, it was adapted to CPU parallel processing in 2010 using the OpenMP API .

      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 OpenCL API, which has been found to be faster, and which supports the use of Graphical Processing Units (GPUs). Funding for the recoding of the WDPM was provided by Agriculture and Agri-Food Canada (AAFC).

      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.
