Corps Shoaling Analysis Tool (CSAT), version 2.5.1

Updated 10 April 2023

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.

Installation Instructions:

1) Check for existing Anaconda/Python3 installation - From the start menu, look for the "Anaconda3" folder and open an Anaconda prompt. Enter the command "conda --version" (without quotes). - If no Anaconda version is reported, proceed to step 2, otherwise go to Step 3. 2) Users without Anaconda should install it: - ACEIT Users - Go to the App Portal and Install 'Anaconda 2019.10 Python 3.7'     - All Other Users - https://www.anaconda.com/products/individual 3) After Install, download CSAT program zip file from here 4) Move the files to a designated CSAT folder and extract files from .zip. Follow remaining instructions from the file "CSAT_py_directions.docx". 5) Input and Output files are available for download here: https://cirp.usace.army.mil/products/csat_districts.php
