The study describes both theoretically and experimentally the flow into a line sink in a linearly density stratified reservoir. The geometry of the boundaries is simplified to a parallel walled duct with the line sink at the center of the fluid. The primary focus is on partitioning the flow into distinct flow regimes, and predicting the withdrawal layer thickness as a function of the distance from the sink. Laboratory experiments verified the conclusions reached from the theoretical considerations. The withdrawal layer thicknesses were shown to be closely predicted by the integral solution. Comparison with measurements made by the Tennessee Valley Authority indicates that in a reservoir the withdrawal layers are approximately one and a half times as large as predicted. The difference in thickness is probably explained by the presence of a certain amount of turbulence in the reservoir, and interference by the rear boundary of the reservoir. (WRSIC abstract).
