Corps Shoaling Analysis Tool : predicting channel shoaling

This report provides background and additional application s of using the Corps Shoaling Analysis Tool (CSAT) and the various output files generated. The CSAT calculates channel shoaling volumes using historical channel surveys and uses the shoaling rates to predict future dredging volumes. Shoaling rate grids can be used to identify hot spots or areas of increased sedimentation. In addition, limiting the time period for analysis to more closely align with a specific event (e.g., meteorological activity or change to dredging schedule/type) may provide insight into the impacts that these events cause to the sedimentation within the channel. The volume tables that quantify the amount of sediment needing to be dredged at depth and time increments also support decision making that will maximize the use of dredging funds and minimize disruption to vessel traffic through the navigation channels.
