Incorporating Spatial and Temporal Variation of Watershed Response in a GIS-based Hydrologic Model
… at the watershed outlet was simulated using the time-area curve concept implemented in a geographic information system (GIS). The goal of this study was to determine if hydrograph prediction accuracy would be improved by accounting for spatial and temporal variation of excess rainfall. Three …

Development and Evaluation of a Gis-Based Spatially Distributed Unit Hydrograph Model
… runoff hydrographs. The SDUH model is a time-area unit hydrograph technique that uses a geographic information system (GIS) to develop a cumulative travel time map of the watershed based on cell by cell estimates of overland and channel flow velocities. The model considers slope, land …
