LARM Two-Dimensional Model: An Evaluation

Center Hill Lake in Tennessee has been the object of several water quality and fisheries management studies over the past decade. The flow regimes of Center Hill Lake were investigated with a numerical, two-dimensional, laterally averaged, hydrodynamic model. This laterally averaged reservoir model (LARM) couples the mass continuity, momentum, and energy equations (with the equation of state) to compute resultant temperatures and flow velocity vectors The LARM model is reviewed, summarizing the model validation process, presenting a summary of the hydrodynamic predicitions, and showing the results of management techniques simulations. Since this was one of the very first uses of the LARM model, the conclusions should be of interest to reservoir water quality managers and modelers.
