Abstract
GEOMORPHIC SETTING: At the project location, the Connecticut River has an annual average discharge of 14,128 cfs, a drainage area of 7,181 square miles. The river banks are steep and unstable; they are composed of non-cohesive soils derived mainly of glacial outwash, deltas, and ancient postglacial dune formations. The project reach is influenced by the presence of hydropower dams upstream and downstream. A pumped storage facility used for managing peak power generation creates additional patterns of water level change. Two significant factors causing bank erosion are weekly fluctuation in water level of 3–5 ft caused by complex hydropower operations and boat wakes of 0.5–1.3 ft from recreational traffic (Fig. 1).
