Summary:
Rock scour is a rock-water interaction problem. National Cooperative Highway Research Program Project 24-29 is geotechnical site characterization in scour-relevant terms for use by hydraulic engineers. Project goals are time-rate of scour and design scour depth at bridge foundations on rock for integration with Federal Highway Administration Hydraulic Engineering Circular HEC-18, Evaluating Scour at Bridges.
Rock scour in natural channels is related to five processes: 1) physical and chemical weathering of exposed rock surfaces, 2) soluble rock dissolution, 3) cavitation, 4), durable rock quarrying and plucking, and 5) degradable rock abrasion. Bridge sites in Florida, Oregon, New York, Utah, and California visited in 2008 provided a range of conditions, data, and samples for the project. Check-list guidance for determining which scour processes can be dismissed and which deserve evaluation.
