A study was conducted to address a shoaling problem in the vicinity of the Cubits Gap distributary on the lower Mississippi River. Upstream from Cubits Gap the river is relatively deep, but the channel depth decreases as it approaches the distributary, where frequent dredging is required. A one-dimensional numerical model was used to evaluate alternative dredging operations and to forecast sediment accumulation. The numerical model was also used to forecast sediment accumulation based on 30-day flow projections. This information can be used to help determine when to initiate dredging fleet mobilization.
