N2 - An example of the process in developing the watershed model is presented. An essential element in the development is the digital elevation model (DEM) from which a delineation of the stream networks and watershed boundaries is obtained. Topological data contained in the DEM is used to determine flow directions, flow paths and accumulations. These computations serve to establish the HEC-1 interface where parameters such as loss rates, base flow, unit hydrograph and routing data are identified. Time of concentration, lag times and travel time along a routing reach are presented as a critical analytical step. Flood plain delineation is achieved in those cases where the stages of the watershed are needed to predict the impact of extremes in precipitation Copyright ASCE 2004.
