Abstract

This sedimentation study of the Green River irrigation canal provides the Green River Canal Company (GRCC) with a detailed aerial map of the Green River irrigation canal system to allow operators to quickly and accurately locate canal structures. Also, an Excel spreadsheet accounting model was created which provides the GRCC with the ability to determine where sedimentation likely occurs throughout the canal under given conditions. This model must be operated within set guidelines to provide reliable results and should be calibrated for increased accuracy. It was determined that with no irrigation (i.e., with no canal structures open except for the final return) a minimum flow rate of sixty-three cubic feet per second is needed to prevent sedimentation throughout the canal. Therefore, a flow rate above sixty-three cubic feet per second is needed for any irrigation along the canal in order to prevent sedimentation.
