The City of Virginia Beach has proposed channel dredging in the Eastern Branch of the Lynnhaven Bay for the purposes of recreations and drainage improvement. It is therefore necessary to examine the possible environmental results of such a project. This environmental assessment is complicated by another proposal to modify the Lynnhaven system. The U.S. Army Corps of Engineers has proposed adding a second canal leading to the Eastern Branch, in order to reduce flood damage. This canal project would affect the Lynnhaven system by increasing nonpoint sources of pollution and by increasing the tidal prism. The water quality consequences of the canal project have been studied (Kuo & Hyer, 1979). The proposed channel dredging project must be studied not only by itself but in combination with the canal project proposed by the Corps of Engineers.

In this study, the water quality model previously calibrated and validated for the Corps of Engineers is used to estimate the effects of the channel dredging in the Eastern Branch of the Lynnhaven.
