Abstract

Analytical determination of pollution susceptibility in coastal marinas R. W. Barber' & M. J. Wearing2 I Computational Engineering Group, CLRC Daresbury Laboratory, U.K. 2 CRM - Rainwater Drainage Consultancy, Bolton, U.K. Abstract A novel analytical model is described for estimating the pollution susceptibility of tidal marinas. The model is based upon a 'tidal prism' or 'zero-dimensional' approach and uses an analytical technique to predict the long-term water quality response. The proposed mathematical model offers a computationally inexpensive alternative to conventional multi-dimensional pollution transport simulations and provides an increased understanding of the flushing characteristics of well-mixed tidal basins. The efficiency of the tidal flushing can be expressed in terms of the pollution susceptibility which can be used to identify marinas at risk from potential water quality problems. Predictions from the analytical formulation are validated against experimentally observed pollut
