An Evaluation Of In-Stream Structures Designed To Provide Fish Habitat, Charles H. Call Jr.

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In-stream concrete structures were studied through model tests and river tests. The model studies indicated that four designs provided good habitat in the model stream. These structures were the inverted weir, the "V" structure, the slab with legs and the cylinder. Through the river studies it was determined that these structures did not influence enough of the total river area to be effective in providing good fish habitat. Also an appreciable amount of yearly maintenance would be required to free the structures from silting in, debris, and vandalism. The slab with legs was the only promising structure.

Economic Feasibility Of Controlling Big Sagebrush (Artemisia Tridentata) On State And Private Rangelands In Utah, Stan D. Hinckley

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Spraying with the chemical herbicide 2,4-D is the most widely used method of controlling big sagebrush. Spraying is very effective in increasing forage production and generally is not poisonous to either man or animals.

Two procedures can be used to calculate the internal rate of return to big sagebrush control: standard and modified discounting. Standard discounting assumes all nonuse costs are incurred in the year of treatment, and the annual income stream is constant throughout the effective life of treatment. Modified discounting correctly assumes the nonuse cost is incurred in the period of deferment, and the income stream does not …
