Abstract:

The objective of this technical note is to briefly describe the Hydrologic Engineering Centers Hydrologic Modeling System HEC-HMS and its application to the Russian River watershed study. HEC-HMS simulates rainfall-runoff at select locations within a watershed given the physical characteristics of the watershed. It is a tool for watershed management that can be used to account for human impacts in regards to the magnitude, quantity, and timing of runoff at points of interest. The current version of HEC-HMS simulates flow and soon-to-be-released versions will also simulate sediment and water quality. Traditionally, stream and subwatershed characterizations have been accomplished using an approach based on Digital Elevation Model DEM terrain analysis within a GIS. The Geo-HMS Arc View extension package was used in developing the topographic values needed to develop the initial watershed model. When the model was completed, a calibration was performed for a select sub-area within the Russian River Watershed.
