Abstract: A method is presented for judging the stability of discrete approximations to the estuary mixing equations. It is applicable to unequal as well as equal reach lengths. A mathematical model is developed for the Hudson River Estuary and the model results are compared to U.S. Geological Survey chloride measurements. For constant flow velocity, an exact solution is developed and compared to the discrete approximation results.
