Abstract
The MSB single-embayment model of pollution flushing from a tidal basin has
been applied to Great Salt Pond on Block Island and the results compared to an
unpublished Rhodamine dye study conducted in 1986. The MSB model is based
on the analytical tidal prism formulation developed by Barber. Both approaches
have previously been validated against physical hydraulic modelling tests
conducted on an idealised constant-depth rectangular basin, and the MSB model
has been found to give excellent agreement against the laboratory data. However,
until this present work, the MSB model has not been applied to a real
embayment.
The present paper details a simulation of pollution flushing from Great Salt
Pond following the release of Rhodamine dye. Results for various values of the
pollution return-flow parameter, b, have been obtained and the agreement
between the measured dye concentration data and the model predictions is shown
to be very good for a suitably chosen value of b.
Keywords: tidal prism, pollution flushing, tidal embayment, Great Salt Pond

1 Introduction
The MSB single-embayment model [1] offers a graphical and numerical
representation of the process of pollution flushing from well-mixed tidal
embayments. The model, which is written in Stella (Stella is a product of ISEE
