Investigation of Flood Protection from Alluvial Fan Flows and Minimizing Impacts to a Sensitive Habitat Preserve: Whitewater River Basin, Coachella Valley, California

by Anna Lantin, (M.ASCE),



Document Type: Proceeding Paper

Part of: Watershed Management and Operations Management 2000

Abstract:

The study describes and evaluates (1) the baseline conditions to hydrology, hydraulics, wind transport of sand, sediment transport by fluvial process, the environment, economics, and (2) presents feasible alternative plans to solve flood-related problems. Alternatives include the preservation of a wind corridor, construction of detention dams, levees, diversion structures, dropstructures, and channelization traversing the alluvial fans. The combined flood control elements extend a distance of over 20 miles. The study area is subject to alluvial fan flows ranging from 1,000 cfs to over 20,000 cfs.
