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 …

Urban Storm Runoff Inlet Hydrograph Study Volume 3: Hydrologic Data For Two Urban Highway Watersheds In The Salt Lake City Area, Utah, Joel E. Fletcher, Cheng-Lung Chen

Reports

The main objective of this study is to develop an accurate design method for computing inlet hydrographs of surface runoff, with average recurrence intervals of 10, 25, and 50 years, from typical urban highway by flood routing technique. Hydrologic data such as the rainfall intensity, runoff flow rate, air temperature, wind velocity, and soil moisture content were collected during rainfall seasons in 1972 and 1973 on two urban highway watersheds in the Salt Lake City area, Utah. These data were used in the verification of a mathematical model simulating the surface runoff from such highway watersheds. The difficulties and inherent …

Results And Evaluation Of An Aerial Creel Survey Technique On Lake Sharpe, South Dakota, Bruce R. Schmidt

Electronic Theses and Dissertations

A creel survey, consisting of two independent surveys, was conducted on Lake Sharpe, South Dakota from May, 1973, through May, 1974. An aerial fisherman count was used to estimate fishing pressure and an angler interview survey was used to estimate catch rates, mean party size, mean fisherman day, and residence of the anglers. The results of the two surveys were combined to estimate harvest. The separate surveys were combined to estimate harvest. The separate surveys allowed optimum stratification and allocation of sampling effort for each. Estimated fishing pressure was 32,643 fisherman-hours, ±9.60% at the 95% confidence level, and the total …

Process Control Of Activated Sludge Treatment, Phase Ii, Richard I. Kermode, Robert W. J. Brett, Joseph D. Pault Jr.

KWRRI Research Reports

Material balances on substrate and microorganisms were derived in conjunction with various mixing configurations thought to accurately describe the activated sludge process. These models include the completely mixed with bypass, plug flow, and plug flow with bypass. Two sets of kinetic mechanisms for substrate utilization and bacterial growth were employed.

A feed forward controller was designed from linear approximations of the material balances derived in the completely mixed with bypass mixing model. Utilizing frequency response methods, the controller was found essentially identical to a completely mixed modeled controller developed in a prior investigation.

Through computer simulation the controller's effectiveness was …

Stochastic Simulation Of Daily Rainfall, David M. Allen, C. T. Haan, Don Linton, Jim Street, David Jordan

KWRRI Research Reports

The design of many water resources projects requires knowledge of possible long-term rainfall patterns. In this project a stochastic model based on a first order Markov chain was developed to simulate daily rainfall at a point. The model is applicable to any point in Kentucky (and other areas with similar rainfall patterns).

The model in its present form is useful in providing rainfall inputs into hydrologic models for designing water supply facilities and other water resources systems. The model uses historical rainfall data to estimate the Markov transitional probabilities. A separate matrix is estimated for each month of the year. …

Retrospective Theses and Dissertations

This report is intended to examine the ecological changes due to mixing in shallow water bodies. Physical, chemical, and biological changes are reported in literature. A literature search revealed the range of mixing nodes or processes. Assessment of ecological changes due to mixing by boating activities had been evaluated in a research project supported by the environmental Protection Agency and conducted at Florida Technological University. The examination of changes due to mechanical mixing on lake ecology simulated in fifty-five gallon drums indicated the sensitivity of such parameters as total Kjeldahl nitrogen, conductivity, pH, temperature, and dissolved oxygen. Problems of reproducibility …

Plating Wastewater Management, Earl Kenneth Ossorio

Retrospective Theses and Dissertations

A study was made of existing methods of management, treatment and disposal of water and wastewater effluents at a large aerospace facility (Martin Marietta Aerospace) in Central Florida. Water consumption and handling were evaluated, with emphasis being placed on the handling of plating wastes, since they are the main contributor of industrial wastewater pollutants at the facility. The flow, storage, and treatment of the plating wastes were studied. Literature concerning plating wastes was surveyed to determine the latest "state of the art" on handling of plating pollutants. Then, the "state of the art" processes were compared with the existing processes …

Nutrient Dynamics And Gas Production In Aquatic Ecosystems: The Effects And Utilization Of Mercury And Nitrogen In Sediment-Water Microcosms, D. B. Porcella, V. D. Adams, P. A. Cowan, S. Austrheim-Smith, W F. Holmes, J. Hill Iv, W. J. Grenney, E. J. Middlebrooks

Reports

Sixteen sediment-water microcosms designed to allow complete gas, liquid, and solid mass balances of gases, nutrients, and mercury were studies under dark conditions or varying light intensity for a period of 189 days. Results indicated that the microcosm technique is a very sensitive method of analyzing microbial dynamics in sediment water systems. Gas quantity and composition changes were easy to monitor and were especially sensitive to light and nutrient variations. Nitrogen fixation occurred in all lighted systems (blue-green algae nitrogen fixers, Anabaena, and others) and was adequate to insure that no nitrogen limitation occurred even though nitrogen limitation was imposed …

The study area is Northwestern Europe which is centered on the North Sea. All the littoral states of Northwestern Europe have major interests in the North Sea, one of which is oil and gas exploitation. This study is developed through the examination of the activities in the North Sea, related to oil and gas production, which tend to join the region together followed by an …

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 …

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 …

Hydraulic And Flow Studies Related To Sediment Transport, Kentucky River, Kentucky, Bruce R. Moore, Michael R. Short, Thomas Wachs

KWRRI Research Reports

This study related the conditions of flow and channel shape to distribution of sediment types in the Kentucky River. Seven distinct types of sediment association were delineated and these have a regular pattern of distribution influenced by the presence of navigation locks and dams. The most suitable locations for commercial extraction of bed material were clearly indicated and the variations of sand size delineated by the study. The irregular discharge pattern of the stream indicates potential problems in the disposal of solid waste pollutants.

A remeasurement of the dredge hole in the Ohio River indicated a continuation of the same …

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 …

Analysis Of Unsteady Flow Toward Artesian Wells By Three-Dimensional Finite Elements, Yang H. Huang, Shen-Jyh Wu

KWRRI Research Reports

A three-dimensional finite element computer program was developed for analyzing unsteady flow toward artesian wells. The program is designed especially for determining the drawdown around an artesian well penetrating fully or partially a nonhomogeneous and anisotropic aquifer of irregular shape and cross section. It can also be used as a general program for aquifer simulation and evaluation. A major advantage of the program lies in the minimum amount of input data required. By assuming the top and bottom boundaries of the aquifer as two arbitrary planes, the aquifer will be divided into six- or eight-node elements, and their nodal coordinates …
