摘要

I develop a sediment transport model for the Sheepscot River to compare it with areas suitable for Atlantic salmon rearing and spawning habitat. I present a predictive model of bed material size that can be entrained under various flood discharges based on cross section profiles, vertical velocity profiles and bed grain size distributions at our six study sites, and monitoring bedload transport using marked particles at a subset of three reaches. Total basal shear stress calculations based on the Karman-Prandtl equation are about 60% of the value calculated by the depth-slope product. Estimates of various hydraulic parameters, including shear stress, at selected sites allow the application of the model to other site locations within the watershed, and identification of reaches with potentially mobile gravel substrate and suitable salmon habitat.
