Effects of Reservoir Regulation on Channel Morphology

by Edward F. Sing, US Army Engineer, District-Sacramento, Sacramento, CA, USA,

Document Type: Proceeding Paper

Part of: Hydraulic Engineering


A case study is presented in which such a multidisciplinary approach was used to evaluate the impacts of regulated outflows from the recently completed Warm Springs Dam Project (Sonoma County, California) may have on the morphology of the Dry Creek channel downstream of the dam. The case study shows how a traditional tool use of a mathematical sediment transport model - together with a multidisciplinary geomorphic analysis of the study reach can be used to mutually verify analysis results as well as evaluate project impacts of reservoir regulation on channel morphology.
