Conflicts In Water Managment, A. Alvin Bishop

Faculty Honor Lectures

Today we hear a lot about the "quality of life" and the "quality of the environment," two terms that everyone understands, but as yet no one has defined. Like others, I will not attempt a definition but introduce my subject by saying that water is intimately tied up with both our life and our environment, and its management has a profound effect for good or bad, depending upon the point of view. Today also, clean water and anti-pollution are popular crusades. Someone or something has to be responsible and engineering and science are convenient scapegoats. Considerable emotionalism is involved and …

Sevier River Basin Floods 1852-1967, United States Department Of Agriculture, Economic Research Service, Forest Service, Soil Conservation Service

Elusive Documents

This chronology of Sevier River Basin floods extends from 1852 to

1967. Most common and destructive are dry mantle floods, which flow as

a muddy mortar-like substance containing 40 to 55 percent water. Hundreds

of tons of protective topsoil are removed from watershed lands,

debris and boulders are picked up as the flow travels down steep stream

channel gradients, and then the flood is debouched into communities and

on to productive cropland.

Analysis Of Water Reuse Alternatives In An Integrated Urban And Agricultural Area, A. Bruce Bishop, David W. Hendricks

Reports

Intoduction

The growing demands on our existing water supplies and the current problems of water shortage emphasize the need for a comprehensive approach to analysis and planning of water reuse. The primary focus, heretofore, has been on the treatment technology for achieving water reuse.

The concept of reuse, however, should be broadened to consider a totally integrated urban and agricultural system. This necessitates a systems analysis where water reuse, together with all other water dispositions, is considered in the context of its contribution to the total water resources pool of a region.

The components of the water resource system are …

Spawning And Early Life History Of Largemouth Bass (Micropterus Salmoides) In Wahweap Bay, Lake Powell, Kent D. Miller

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Spawning time and habitat of largemouth bass, survival of embryos, and growth and food habits of fingerlings were studied in 1968 and 1969 at Wahweap Bay, Lake Powell. Spawning began in mid- to late-April, when mean daily water temperature at nesting depths was 14.4-15.0 Centigrade (58-59 Fahreheit), and continued until mid-June. Most spawning took place on the northeast shore of the bay. Sandstone rubble was the most commonly used bottom type for nesting, either at the base of ledges or around large sandstone boulders. Mean nest depth increased from 1.63 meter to 4.54 meters (5.36 feet to 14.90 feet) in …

Telemetered Heart Rates Of Free-Living Uinta Ground Squirrels In Response To Social Interactions, Robert L. Ruff

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Free-living Uinta ground squirrels (Spermophilus armatus) were instrumented with miniaturized ECG radio-transmitters to measure their short-term and long-term heart rate responses to social interactions. A continuous trapping and direct observation program prior to and during the study provided complete behavioral and life history information for virtually all ground squirrels on the 22-acre study area.

Three broad categories of heart rate information were obtained: responses by squirrels (1) in their burrows, (2) above ground during social interactions, and (3) above ground when animals were not fighting and when conspecifics were both absent and present.

Marked changes in the heart …

Effects Of Season And Intensity Of Use On Desert Vegetation, C. Wayne Cook

UAES Bulletins

Desert ranges of the Great Basin area support about 9 million cattle and sheep for 5 to 6 months each winter. Many of these same ranges are used by cattle year-long.

If forage is not available on desert ranges, livestock have to be wintered on farmsteads or in feedlots after they are forced from the mountains and foothills by snow. Since feeding during the winter is expensive and reduces the economic efficiency of the range livestock operation, there is real advantage in properly managing the desert ranges and conserving the supply of forage for winter grazing.

Managing desert ranges for …

The Effect Of Carbon On Algal Growth--Its Relationship To Eutrophication, Joel C. Goldman, Donald B. Porcella, Joe E. Middlebrooks, Daniel F. Toerien

Reports

Introduction: Natural and cultural eutrophication (enrichment with nutrients) frequnetly results in excessive algal growths thereby reducing the beneficial uses of surface waters (Hasler, 1947; Thomas, 1955, Edmondson et al., 1956, Oswald and Golueke, 1966, Skulberg, 1967, Mackenthun et al., 1968, Goldman and Armstrong, 1969, McGauhey et al., 1968,1969, 1970a, 1970b). Recent reviews emphsize that the prevention of further reduction in the quality of water resources requires the implementation of effective control measures (Goldman, 1965, Steward and Rohlich, 1967, Middlebrooks et al., 1969, Rohlich, 1969). Effective control of cultural eutrophication must involve the manipulation of those factors which affect algal growth, …

Inverse Solutions To Three-Dimensional Free Surface Potential Flows, Roland W. Jeppson

Reports

Methods are developed and defined for obtaining numerical solutions to three-dimensional, free surface, invisvid, incompressible fluid flows and three-dimensional free surface Darcian flow in porous media. Since those boundaries consisting of free surface are unknown a priori, a solution to the space boundary value problem resulting from a formulation in the physical space is very difficult, if not impossible, to obtain. Consequently, the methods described herein are based on a formulation in a space defined by a potential function and two mutually orthogonal stream surfaces whose intersections define the streamlines of the flow. In this space the positions of free …

Extending Utility Of Non-Urban Water Supplies, Jay M. Bagley

Reports

Extending the utility of an existing water supply in any river basin suggests a management-planning approach under three general guiding principles: (1) minimize depletions wherever possible (thereby maintaining a greater manageable quantity with subsequent potential to satisfy more uses); (2) generally preserve, protect, and improve water quality (thereby retaining its itility for use by a wider variety of potential users); and (3) make carefully considered allocations (thereby assuring multiples duty, more optimal sequencing, and shifts in use to conform to current and projected soil preferences). There are many technological and managerial techniques that can be employed to implement these principles. …

The Behavior Of Pvc Pipe Under The Action Of Water Hammer Pressure Waves, Gary Z. Watters

Reports

Introduction: Hydraulic transients, commonly referred to as water hammer, occur in a hydraulic system whenver the velocity of flow in any one of the pipes in the system is caused to change. The magnitude of the pressure waves generated by a given change in velocity depends on the geometry of the pipe system, the magnitude of the velocity change and the elastic wave velocity in the system componenets. In turn, the elastic wave velocity depends on the modulus of elasticity of the fluid and the pipe material, the size and thickness of the pipe, the method by which the pipe …

A Computer Model Of The Quantity And Chemical Quality Of Return Flow, Jimmie L. Thomas, J. Paul Riley, Eugene K. Israelsen

Reports

A hybrid computer program is developed to predict the water and salt outflow from a river basin in which irrigation is the major water user. A chemical model which predicts the quality of water percolated through a soil profile is combined with a general hydrologic model into form the system simulation model. The chemical model considers the reactions that occur in the soil, including the exchange of calcium, magnesium, and sodium cations on the soil complex, and the dissolution and precipitation of gypsum and lime. The chemical composition of the outflow is a function of these chemical processes within the …

Detergent And Non-Detergent Phosphorus In Sewage, Donald B. Porcella, E. J. Middlebrooks

Reports

Introduction: Quantitative data on nutrient levels in sewage from homes which are using heavy-duty detergents and which have been restrcited from using such detergents is necessary before rational decisions on the removal of phosphorus from detergetn can be made. Furthermore, the effect of various standard sewage treatment schemes on phosphorus levels should be evaluated to determine the relative cost of such treatment. Then the cost (to society, the environment, and to the taxpayer) of phosphorus removal from detergent and/or from sewage effluents can be estimated and such data utilized to make the appropriate policy decisions. The report herein presented is …
