Abstract: In the broadest sense of systems analysis, the Hydrologic Engineering Center (HEC) has been actively applying systems analysis techniques since its inception in 1964. HEC's basic systems analysis method has been the ...

Abstract: In 1945, C. O. Clark proposed a method to develop synthetic unit hydrographs for the modeling of watershed rainfall response. His technique utilizes two components: a translation hydrograph and a linear reservoir routing. ...

Abstract: Geographic information systems (GIS) provide a digital representation of watershed characteristics used in hydrologic modeling. This paper summarizes past efforts and current trends in using digital terrain models and GIS ...

Abstract: A physically based stochastic watershed model is used to estimate runoff prediction uncertainty for small agricultural watersheds in Hastings, Nebraska. The stochastic nature of the model results from postulating a ...
