PARAMETER-ESTIMATION AND STOCHASTIC INTERPRETATION OF THE TRANSIENT STORAGE MODEL FOR SOLUTE TRANSPORT IN STREAMS

A stochastic model for solute transport in streams with transient storage zones is presented. This model has an analytic solution in terms of a rapidly converging infinite series. Besides being computationally efficient, this solution is of interest because the terms of the series can be interpreted physically. Simple methods for roughly estimating storage zone parameters directly from tracer injection data are introduced. These methods give quick estimates of these parameters without requiring solutions to the model equations.
