Scour Study for Bridge Design on Temecula Creek

by Howard H. Chang, (M.ASCE),



Document Type: Proceeding Paper

Part of: North American Water and Environment Congress & Destructive Water

Abstract:

Channel-bed scour was studiedfor the proposed new Pala Road Bridge on Temecula Creek in Riverside County, California. In order to determine the general scour, sediment transport and potential stream channel changes were simulated using the mathematical model FLUVIAL-12. General scour so determined reflects the channel alignment, bridge configuration, channel curvature, and other factors that may affect channel-bed scour. The bridge is located in a curved channel reach. Because of channel curvature, channel-bed scour is greater near the concave bank. The information on general scour and local scour were used in bridge design.
