LATERALLY AVERAGED HYDRODYNAMICS MODEL FOR RESERVOIR PREDICTIONS

A laterally averaged 2D computational model, is presented that is appropriate for modeling density currents and other flows in long, relatively narrow reservoirs where the water surface level does not vary significantly and there are no lateral inflows or outflows. Called the laterally averaged hydrodynamics model (LAHM), the model utilizes a boundary fitted orthogonal coordinate mesh that affords to it the capability of accurately modeling flows for which the bottom depth may vary significantly along the reservoir length. The solution procedure developed for this model is appropriate for flows in reservoirs and other water bodies where the average depth is much smaller than the flow-wise length.
