Hydraulic Characteristics Of Labyrinth Weirs, Corwin M. Willmore

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

Primarily, half-round crest labyrinth weirs were tested in this study with the side leg angle (a) ranging between 7 to 35 degrees. Historical data was primarily limited to quarter-round data. This study presents data and equations for estimating the discharge coefficient for labyrinth weirs with both half-round, quarter-round, and two Ogee-type crest weir shapes . A method is presented for comparing the flow capacity between weirs in order to determine the most efficient weir at a given Ht/P. For a labyrinth weir with the crest shape,# of cycles (N), and the cycle width (w) held constant, the discharge coefficient (Cct) …

Interim Sediment Management Plan For First Dam, Logan River, Thirumurugan Bose

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

Sediment is a serious problem in the management of dams all over the world. In this project an interim sediment management plan for First Dam, on the Logan River in northern Utah, is discussed. The objective of the plan is to control the sediment budget of the reservoir in such a way that other reservoir maintenance activities (e.g., unusual draw downs for structural repairs) will produce minimal downstream environmental impacts on water quality and aquatic resources.

This report presents a detailed literature review of the various sediment management practices used for reservoir sediment control. It also discusses the downstream effects …

Analytical And Numerical Investigation Of A Mechanically Stabilized Earth Wall On I-15, Aaron S. Budge

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This dissertation is the culmination of extensive research into the behavior of a mechanically stabilized earth (MSE) wall at I-15 and 3600 South in Salt Lake City, Utah. The wall is about 30 ft tall and is constructed on a compressible, soft clay foundation. Research on this project has included extensive instrumentation and monitoring of stresses and deformations in the wall and its foundation, a study of the effects of drilling and sampling method on disturbance of samples, and extensive laboratory testing to determine strength and deformation properties of soils at the site. The results of these portions of the …
