Abstract Details

2012, Master of Science (MS), Ohio University, Civil Engineering (Engineering and Technology).
The purpose of this thesis was to investigate the sediment transport capacity of the Hocking River in the 9-km long channelized reach between White's Mill and the State Route 50 Bridge, located on the eastern side of Athens, Ohio. Sediment transport capacity was determined using Hydrologic Engineering Centers River Analysis System (HEC-RAS) 4.1 and was compared to inflowing sediment rates to determine overall channel efficiency. Sediment transport efficiency as well as RUSLE sediment delivery ratio analysis indicate the channel has insufficient sediment transport capacity during average and below average flow conditions. Approximately, 1/8th of the channel has efficient sediment transport capacity during flood conditions. The threshold sediment delivery rate that would allow for sufficient transport was determined for the average flow and 1998 flood condition, based on erosion potential estimated by the Revised Universal Soil Loss Equation. Threshold sediment delivery rates indicate that sediment accumulates during average or low flow conditions, when the channel has insufficient sediment transport capacity. A fraction of the accumulated sediment is then removed during flood events, when the channel has more than sufficient capacity.
