Description

NWS/OHD has started to develop a distributed modeling system that is based on gridded rainfall-runoff and hillslope-channel routing models. A grid data structure is a discrete representation of the terrain based on identical square cells. Grids are used to describe spatially distributed terrain and channel parameters, and one set of parameter values is necessary for each grid cell represented. The system will require estimation of rainfall/routing parameters for a large number of hydrological units (pixels). The basic spatial resolution will be on the order of the HRAP pixel size (4-x 4-km) although simulations may be performed using different resolutions depending on user needs and basin characteristics. We expect that recent developments in DEM/GIS high-resolution data bases in combination with watershed geomorphology laws of a river network structure and local empirical relationships (e.g., cross-section versus basin area and channel order relationships) may be used to derive distributed routing parameters. Channel information collected by USGS at discharge measurement locations will also be very helpful for the development and testing.
