Abstract: Based on the flow-continuity equation, scour geometry, and a generalized form of the power-law formula for flow resistance in an alluvial channel, a semiempirical analysis of equilibrium local clear-water scour at an ...

Abstract: Location of maximum scour depth is a key feature for the accurate design of scour countermeasures. Experimental results show that the maximum scour depth around wide setback abutments migrates to a location further downstream ...

Abstract: This study shows that a jet-flipping phenomenon may occur during the scouring process downstream of a sluice gate. The flipping consists of a digging and a filling phase. The former scoured the bed, and the latter refilled ...

Abstract: A user-friendly total bed-material load transport formula for flow in alluvial channels under equilibrium transport conditions has been developed based on dimensional analysis. The main advantages of this formula are its ...

Abstract: A simplified model for the computation of boundary shear stress distributions acting on the flow perimeter of closed ducts is presented. The model assumes that the surplus energy within any control volume in a three-dimensional ...

Abstract: An analysis is presented of the 309 known laboratory data for local scour depth developed by two-dimensional (2D) horizontal jets, which leads to development of a new comprehensive prediction equation. The new equation ...

Abstract: Based on the continuity of flow and sediment, an analysis on scouring in long contractions is conducted with a formula obtained from measured sediment discharge in long contractions and a formula for the flow resistance ...
