Stochastic Model for BOD and DO in Estuaries

Using the additional assumption that the degrading process in nature is discrete rather than continuous, one obtains a stochastic model for the process. Unlike the results previously obtained for streams the mean effects did not coincide with previously obtained deterministic results. The mean effect and the fluctuations about this effect were compared with data from the Potomac estuary. The comparison is remarkably good, and strongly indicates the validity of the stochastic model.
