Description: Technical report
A numerical model study of the Hoosic River Flood-Control Channel was conducted to determine the flow conditions with the channel as it presently exists as compared with the as-built conditions. Sediment has accumulated in certain portions of the channel resulting in relatively large areas of deposited material that may inhibit flood-flow conveyance. The two-dimensional depth-averaged module of the Adaptive Hydraulics (ADH) finite element flow solver was used to obtain velocity information and water-surface elevations. Validation of the numerical modeling system was completed by comparing simulation results with published physical model data. The model was then used to evaluate the flow conditions associated with the as-built channel configuration. The existing channel conditions were then simulated to determine the water-surface elevations that are to be expected with design discharge and the channel in the present day condition. Finally, the flow conditions with two alternative channel modifications were evaluated. These modifications were proposed channel restoration configurations designed to improve habitat and aesthetics.
