- Description
- The purpose of the study is to evaluate the adequacy of the Warm Spring Dam Spillway. The analysis shall determine the downstream inundation caused by both with and without failure analysis of the dam for the Probably Maximum Flood (PMF), as well as the 50-, 100-, 200-, and 500-year frequency based storms and a sunny day failure scenario. The District just completed a similar study for Coyote Valley Dam in July 2009; the same mythology shall be used in this study. This report shall be made available to the contractor prior to the Fee Proposal due date. The Coyote Valley Dam study routed the flood hydrographs from Coyote Valley Dam, thru the Russian River watershed (1400 square miles) to it's terminus at the Pacific Ocean. The Russian River hydrology model developed for the Coyote Valley Dam study shall be used for this study, with modifications to the Dry Creek watershed (270 square miles). The Russian River hydrology model, as well as the flow data, precipitation data, GIS data, land use data, hydrologic models, and other data generated as part of the Coyote Valley Dam study shall be provided to the contractor for use in this study. Again, only the Dry Creek watershed shall require a detailed analysis, the existing Russian River hydrology model shall be used for the Russian River portion of the modeling effort. The hydrology model (HEC-HMS) will be calibrated and validated to the same historic data as the Coyote Valley Dam Study. Calibrated models will be used to model all of the events. The models will be run for with and without failure analysis of the dam for the 50-yr, 100-yr, 200-yr, 500-yr, and PMF events and a Sunny day failure scenario.
