Salinity intrusion in estuaries has traditionally been predicted by use of physical models and more recently by numerical models. Analytic techniques have seen quite limited use because the complex nature of estuarine flows and salt transport make their findings qualitative instead of quantitative and because of the lack of self consistent field data sets. The purpose of the work described is to begin development of a more realistic analytic method using data from a number of physical model studies. It is intended that the method be easily and quickly applied to situations where proposed modifications to the estuarine system (e. g. channel deepening) must be roughly evaluated.
