Abstract:

The Rio Hondo Flood Control Channel located within the Los Angeles County Drainage Area (LACDA) is part of a Comprehensive flood control system which includes 20 dams, 129 debris basins, and 386 km (240 miles) of improved flood control channels. The U.S. Army Engineer District. Los Angeles, plans to increase the level of flood protection provided by the existing system. Increasing the capacity of the Rio Hondo Flood Control Channel is included in this plan and consists of installing parapet walls on top of existing channel leaves and modifying bridges which constrict the flow. A physical model study is currently being conducted by the Hydraulic Structures Division of the U.S. Army Engineer Waterways Experiment Station for the Los Angeles District to assist in the final design for the Rio Hondo Channel. The model results to date are presented along with the modeling techniques used for the study.
