Gravel Bed River Scouring Analysis Downstream of Block Ramps

The paper describes the scouring process of a river bed downstream of block ramp hydraulic structures. The scour depth of the river bed downstream of the block ramps was calculated by using several different empirical formulae from the literature. The calculated results were verified with the measured results collected during the field measurements. The current paper presents the most appropriate formulae for the comparison of the scouring results with the obtained field measurements. It was found that the calculated values of scouring are usually much higher than those observed in the field. The most important aim of this paper is to verify the obtained empirical formulae for scouring downstream of block ramps based on the results of the field measurements.
