An Analysis On Soil Properties On Predicting Critical Hydraulic Gradients For Piping Progression In Sandy Soils, Tammy Jacobson

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

Piping is a form of internal erosion in which soil particles are eroded at a seepage exit location due to the forces imposed on the particles by seeping water. Laboratory testing was performed on a variety of soils in order to assess a correlation between unit weight, angle of internal friction, grain size, gradation, and void ratio and the critical hydraulic gradient at which piping initiates and progresses. A multi-variable regression analysis was used to form equations to predict critical hydraulic gradient based upon each of these soil parameters. Variations in the accuracy of these equations are thought to be …

A Critical Analysis Of Water Rights And Institutional Factors And Their Effect On The Development Of Logan River, Frank W. Haws

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The physical setting of the Logan River Drainage Basin is first described with emphasis on the hydrologic and climatic factors that made the river an economic and social benefit.

The historical development of the river by man is then traced, and changes in water use patterns are pointed out. Methods used to administer water rights as water use patterns change is then described.

Legal controversies over water rights on the river are examined and methods of solving problems analyzed. A recent law suit between Logan City Corporation and the Logan River Water Users Association is examined in detail and the …
