A watershed modeling system (WMS) has been developed to address the needs of surface water rainfall/runoff computer simulations. WMS, developed at the Engineering Computer Graphics Laboratory (ECGL) at Brigham Young University, is part of a multi-year project funded in part through the U.S. Army Corps of Engineers, Waterways Experiment Station (WES). WMS can be used as a pre and post-processor for both traditional lumped parameter models such as HEC-1 and TR-20 as well as for spatially distributed finite element and fmite difference models. Both kinds of models are set up from a high-level conceptual model comprised of points, arcs (polylines) and polygons.
