A Methodology for Determining Scour Depth around Structures in Gravel-bed Rivers

The objective of this research is to develop a rigorously tested and rapidly deployable methodology for bridge owners that will accurately predict scour at new bridge foundations and evaluate scour at existing bridge foundations in gravel-bed rivers by (1) providing reliable data for fluid-induced forces, required to generate incipient motion in the surface and subsurface layers of gravel-bed rivers; and (2) combining fluid-induced erosion forces, and incipient motion data to predict scour depths at bridge foundations with gravel-bed rivers that have ¼ inch gravel to 12 inch cobble mixtures with varying sand content up to 20%.
