Interior Floodplain Flood-Damage Reduction Study

Evaluation of flood risk in an interior watershed (one protected from flooding by a levee) requires application of watershed, channel, statistical, and economic models in an integrated, coordinated manner. The Strong Ranch Slough and Chicken Ranch Slough watershed in Sacramento, California is such a watershed. We describe herein how we used standard-of-practice models within a coincident-frequency analysis framework to evaluate existing flood damage potential and flood damage potential with a variety of proposed damage-reduction measures.
