Prediction of Localized Scour Hole on Natural Mobile Bed at Culvert Outlets
Systematic physical tests were conducted to evaluate the natural mobile bed erosion without any protection measure. The experiments were performed using a hydraulic model built at the Laboratory of Hydraulic Constructions of the Swiss Federal Institute of Technology in Lausanne.In the preliminary tests, the principal parameters were found to be the discharge, tailwater depth, pipe diameter, and the bed material properties. Upon the completion of scour tests, an empirical analysis was conducted to correlate the maximum depth, length, width and distance of maximum depth from the outlet, tailwater depth and downstream bed characteristics. The maximum depth, length and width of the scour hole were presented in dimensionless relationships for various of discharges and tailwater depths. Based on the tests results, general applicable design charts and formulas for defining the local scour hole have been developed. The results of present experimental study have compared with some results of other authors.
