Corps Shoaling Analysis Tool (CSAT), version 2.4.1

Updated 13 May 2021
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. 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.
CSAT 1.0.x was run using a Matlab executable file and requires survey upload through eHydro for the channel. CSAT 2.x migrated from Matlab to using Python instead. CSAT is being developed jointly by CIRP and the Asset Management (AM) program.
