Description of the Hydrologic Engineering Center's Hydrologic Modeling System (HEC-HMS) and Application to Watershed Studies

摘要

The objective of this document is to describe the Hydrologic Engineering Center's Hydrologic Modeling System (HEC-HMS) program and its applications to watershed studies. HMS has the capability to serve as a cornerstone program with respect to the watershed perspective approach. HMS can simulate the rainfall-runoff at any point within a watershed given physical characteristics of the watershed. It is a tool for watershed management in that an HMS model can be developed to account for human impact to determine the effect on the magnitude, quantity, and timing of runoff at points of interest. Results from an HMS model can be used by a number of other programs to determine impact in areas such as water quality and flood damage.
