Abstract: Two simplified mass transport models for partially mixed estuaries were evaluated using data from the Patuxent and James Estuaries. The first of the models was developed by Pritchard in the late sixties - the box model. The second approach was recently developed by O’Connor and Lung for two layer mass transport patterns. The calculated transport patterns were used to predict the longitudinal salinity profiles for the estuaries. The box model, which does not require hydraulic geometry, calculated a very rough approximation of the transport pattern. The final results consistently overestimated salinity concentrations along the estuary. The O’Connor/Lung model was more rigorous in deriving the transport coefficients.
