Abstract
The MSB coupled embayment model of pollution flushing from a tidal basin has
been applied to the Queenstown Creek of the Chesapeake Bay system and the
results compared to an unpublished Rhodamine dye study conducted in 1987.
The MSB model is based on the analytical tidal prism formulation developed by
Barber. Until this present work, an MSB model of cascading tidal segments has
not been applied to a real embayment. Tidal prism analyses have been validated
against physical hydraulic modeling tests and one segment Mecca-Severino-
Barber (MSB) models have shown agreement with real world dye studies,
prompting this study of the more complex coupled embayment model. Presented
in this paper is a simulation of pollution flushing from Queenstown Creek into
the Chester River following the release of Rhodamine dye. The results are found
to be in general agreement with the field data, and the nature of the MSB
coupled embayment model obviates the need for the pollution return-flow
parameter, b.

1 Introduction
Pollution flushing from coupled well-mixed tidal embayments is represented
graphically and numerically in the MSB Coupled Embayment Model (MSBCEM)
[1]. Written in Stella [7], realistic basin bathymetries are incorporated [2]
as is the dynamic loading of pollutants [3]. The rate equations of Barber’s tidal
