Abstract
Intercomparison Project (DMIP). The purpose of the project is to explore issues related to distributed hydrological modeling. WATFLOOD is a distributed hydrological model developed at the University of Waterloo. WATFLOOD subdivides the watershed into grids, and is therefore ideally suited for use with gridded data sets, such as radar data. WATFLOOD uses the Grouped Response Unit methodology to account for landcover inhomogeneity. All areas of similar landcover within a grid (not necessarily contiguous) form a GRU, and runoff is calculated for each GRU separately. The runoff estimates for each GRU are summed to calculate the grid runoff, which is then routed downstream to the basin outlet. The parameters for WATFLOOD are landcover based, and may be transferred between basins. The model has been used for a variety of basins within Canada, with a single set of (landcover-based) parameters. The WATFLOOD model has been used to develop streamflow estimates on the DMIP test basins. This presentation will describe the model itself, how the DMIP watersheds were setup for WATFLOOD, and the initial and calibrated streamflow estimates.
