Variation in Local Scour Profiles of an Embankment Pond

Abstract

This paper intents to identify the variation in local scour profiles of an embankment pond under varying pond water depths. The embankment pond was constructed to regulate the water issuing from the tunnel of a hydropower station before releasing it to the river. To avoid the structural collapse of any hydraulic structure, the scour process is one of the primary factors that must be controlled. Sediments (soils and sands) are composed of aggregation of individual grains that have varying density, volume, shape and orientation. Therefore an investigation is quite important on interactions between the fluid and sediment particles in open and pipe channel flows in hydraulics and river engineering. The variation in pond water level has significant effect on the scour that may occur on the bed of the embankment pond. This paper highlights the variations and suggests for maintaining certain pond water level to lessen the scour hazards.
