Abstract: Selective withdrawal has many applications in water quality management of reservoirs. Topographic effects such as a sill alter the withdrawal layer properties. In this study, the effect of a sill on selective withdrawal of a two-layer fluid through a line sink in a rectangular reservoir is studied using two-layer hydraulics theory. The results are compared to the experimental measurements. The results show that disturbances in form of a surge are responsible for establishment of selective withdrawal upstream of the sill. The amplitude and velocity of the surge depends on the sill height and Froude number. A good agreement between the theory and the experiments are obtained.
