Interpretive Summary:

Technical Abstract: The WEPP model requires input on climate, topography, soils, crops/management, irrigation, channels, impoundments, and watershed structure. The model also can create a large number of output files, including data which allow graphical depiction of spatial and temporal erosion on a hillslope. The watershed and hillslope interface programs allow the WEPP user to quickly and easily create and access model input and output files, file building programs, and output viewing programs. Climate, soil, slope, crop/management, and irrigation input file builders can all be accessed from the interface program. Once a line or lines of WEPP run information have been entered into the interface program, the WEPP model can be run, and then the output files created by WEPP can be viewed and in some cases plotted. The watershed interface program consists of two main input areas: a watershed description grid box in which components of a watershed (hillslopes, channels, and impoundments) are entered in a grid table; and a watershed option box in which the desired input parameters and output options for the watershed simulation are entered. File builders to describe hillslope, channel, and impoundment components are accessed from the interface program. The interface itself creates the necessary watershed structure file. The Crop Parameter Intelligent Database System (CPIDS) was developed as part of the WEPP effort to assist users in developing plant parameter inputs to the WEPP model for crops other than those specified in the original WEPP User Requirements document.
