Regional Development: An Econometric Study Of The Role Of Water Development In Effectuating Population And Income Changes, Herbert H. Fullerton, Chris W. Lewis, Jay C. Andersen, John E. Keith, Reed Willis

Reports

Twelve measures of regional economic growth, including populations and three measures of income were compared for areas with and without water investment in 246 counties and 42 water resources subareas in the states of Utah, Colorado, New Mexico, Montana, Wyoming, Idaho, and Nevada. Simple mean omparisons for these measures compiled for the decades of 1940-1950, 1950-1960, and 1960-1970 failed to support the hypothesis that economic growth of those counties and subareas receiving water investment was significantly highter than in those areas which did not, with the possible exception of the 1940-1950 decade. This result is obciously tempered by the fact …

Optimal Highway Safety Improvement Investments By Dynamic Programming [Dec. 1974], Jerry G. Pigman, Kenneth R. Agent, Jesse G. Mayes, Charles V. Zegeer

Kentucky Transportation Center Research Report

The process of determining which projects to implement under a given budget, and which to defer until later, is central to the planning and management of highway systems. With a limited budget for construction, maintenance, and safety improvements, investments which will produce the optimal benefits must be chosen. This is often impossible to accomplish without the aid of a computer because of the complexity of the problem. Dynamic programming has been tested and verified as an efficient method for selecting priority projects to derive maximum benefits. The applicability of dynamic programming to the safety improvement program is demonstrated in this …

Multiple Uses Of Utah Irrigation Canals: Cache County As A Case Study, James J. Kennedy, Komain Unhanand

Reports

Irrigation use is an obvious benefit of Utah canals that has been recognized for over 100 years. This study attempts to illustrate other, less obvious, uses. the major use examined was recreational, but canals are presently functioning as storm drainage systems and have potential for diverting flood crests in many river systems.

Recreational use of canals falls into two categories. There is passive use such as its landscape values, affects on creating shade and bird-wildlife habitat, etc., that is difficult to quantify but no less important than active canal use such as tubing, hiking, bank-play, bicycling, etc. We selected several …

Development And Preliminary Application Of Mathematical Models To The Weber Basin, W. J. Grenney, D. S. Bowles, M. D. Chambers, J. P. Riley

Reports

The adoption of stream standards, whether for direct application or for the establishment of realistic effluent standards, creates a need to predict the impact of pollution loads on river water quality during critical flow periods or as the result of future user demands. Because of the complexity of aquatic systems, mathematical models are an excellent medium for bringing together the state-of-the-art knowledge from a variety of disciplines into a form which can be readily applied to practical problems. Applying a mathematical model to a river system has the added advantage of providing a structure for the systematic consideration of the …

Rock Evaluation For Engineered Facilities, D. J. Hagerty, Robert C. Deen, M. W. Palmer, C. D. Tockstein

Kentucky Transportation Center Research Report

The need for comprehensive information on the characteristics and behavior of earth materials has been recognized for many years, perhaps for as long as significant construction has taken place in and on the surface of the earth. In recent years, however, the magnitude and complexity of engineered construction has greatly increased, resulting in a corresponding increase in the need for information on the engineering properties of soil and rock materials, Direct testing of soil and rock can be utilized to furnish necessary information. However, both field and laboratory testing can be extremely expensive, particularly where testing must include applications of …

Highway Pavement Maintenance Costs And Pavement Type Selection, Donald C. Newberry Jr., Jesse G. Mayes, James H. Havens

Kentucky Transportation Center Research Report

A long-term analysis of pavement maintenance cost has been performed. The analysis does not include construction or resurfacing costs. The sample of pavement sections investigated were chosen to best represent the entire state. These sections were classified by pavement type; either bituminous concrete, portland cement concrete, or composite. The cost per lane mile (kilometer) per year was calculated for each pavement type by year and by age of pavement. Apparent differences in pavement maintenance costs between the two basic types of pavements were adjudged insignificant from the standpoint of determining pavement type. Because of poor or erroneous cost reporting, actual …

Bulletin 3933 - Trickle Irrigation For Home Gardens, K Cole

Bulletins - 3000 - 3999

The use of trickle irrigation in the home garden can save money, time and water.

Trickle irrigation is a concept first used in glasshouses in England, then applied to field crops in Israel and developed and refined in Australia and America. Today it is widely used in orchards, vineyards, vegetable gardens and now has gained wide acceptance in the growing of ornamental plants.

Any good trickle system uses small quantities of water over an extended period of time. In the home garden, flows of 2.25 litres to 4.5 litres per hour are usual though for small shrubs lesser amounts may …

A Rock Classification Schema, Robert C. Deen, C. D. Tockstein, M. W. Palmer

Kentucky Transportation Center Research Report

The need for engineering data on earth materials for use in site selection, design, construction, and maintenance of major engineering structures is generally accepted. Probably the most pressing need is for such data to use in preliminary considerations of site selection and design alternatives. Maps and(or) surveys giving the areal distribution of earth materials and their characteristics, together with topographic maps available for many areas, would permit much preliminary work on engineering structures to be done without the engineer ever having to leave his office.

A Rock Evaluation Schema For Transporting Planning In Kentucky, C. D. Tockstein, M. W. Palmer

Kentucky Transportation Center Research Report

The initial goal was to devise an engineering classification system for intact rock samples based on simple index tests which could be used to categorize Kentucky surface and near-surface rock types and assist Kentucky Department of Transportation personnel in planning for transportation facilities. While conducting the literature survey, several facts become apparent:

1. a large number of rock classification systems, geologic and technical, general and specific, already existed;
2. an equally large number of index tests had been devised; and
3. there was a lack of communication among those involved in specialized areas of rock-related work (geologists, civil engineers, mining engineers, etc.), and, …

Finite Difference Solution For Drainage Of Heterogeneous Sloping Lands, Fahd Salih Natur

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The two-dimensional problem of tile drainage on sloping heterogeneous lands was considered. The land surface and the impermeable boundaries of the problem were of a general shape. The flow in both the saturated and unsaturated zones was considered and the system was treated as one composite system. The problem was solved by a finite difference numerical method using the successive over-relaxation iterative (SOR) method for the steady state case with no local recharge, and a combined Newton inner iteration and successive over- relaxation outer iteration for the transient state case with local recharge. Both the rising water table and the …

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.

Interactive Hybrid Computer Program As An Aid For Teaching Hydrology, Arif Hikmet Atali

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

The science of water resource planning and management implies the utilization of available water supplies in order to meet specific goals and objectives (Hill and Riley, 1972). Essential to effective planning and management is the consideration and analysis of all possible alternatives. Past research at Utah State University has demonstrated that the hybrid computer simulation of hydrologic processes is a reliable planning technique which provides the capability to examine many possible alternatives in a short period of time (Hill et al., 1970; Riley, 1970; and Riley et al., 1967). This technique, because of its interactive characteristics, is valuable also in …
