Water quality management of estuarine systems

In this paper sensitivity analysis and specific optimal control theory are applied to the problem of water quality management of estuarine systems. The approach is based on the ultimate availability of a network of automatic monitoring stations along the stretch of the estuary under consideration. The stations will report to a central processing unit the current status of all conditions which seriously affect the functioning of the water eco-system. It is further assumed that water quality standards on a regional basis have been established according to water use and that physical aspects of the estuary (to be used as inputs to the mathematical models) are available or can be obtained through field measurements.
