Minimum Velocities For The Suspension Of Fine Sediment In The Green River Canal, Michael W. Stoeber

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

This paper focuses on a canal in the Gunnison Valley, located in central Utah, which diverts water from the sediment-laden Green River. Grain size analyses were performed on sediment samples taken from the canal. These grain size analyses were used to determine the grain size distribution of the fine sediment, classify the fine sediment, and compare the fine sediment to a sediment deposit in the Green River. The critical incipient velocity for the D₅₀ and D₁₀₀ and the critical grain entrainment velocity corresponding to the D₉₅ were determined through flume experimentation. Two methods, developed by prior researchers, …
