Corps Shoaling Analysis Tool (CSAT), version 1.02

Updated 8 March 2019
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 is run using a Matlab executable file and requires survey upload through eHydro for the channel. CSAT is being developed jointly by CIRP and the Asset Management (AM) program.
System Requirements for use of website: (**Note - this requires Administrator privileges for installation)
For Installation instructions, choose machine type below.
  • Connect to internet for Matlab runtime installation
  • CorpsNet users without MATLAB should request via ACE-IT app portal
    - Go to
    - Search for Matlab Runtime and select MathWorks MATLAB Runtime R2017a 9.2
  • After Install, download zip file from here

  • Connect to internet for Matlab runtime installation
  • Download zip file from here and run Installer.
    - If MATLAB or proper version of MATLAB Runtime is already installed, only CSAT will be installed.
    - Otherwise, MATLAB runtime will be installed first (lengthy download and install time)
