A Survey And Evaluation Of Shallow Groundwater Contamination Hazards In The State Of Utah, Edward P. Fisk, Calvin G. Clyde Jan 1981

A Survey And Evaluation Of Shallow Groundwater Contamination Hazards In The State Of Utah, Edward P. Fisk, Calvin G. Clyde

Reports

A survey was made to appraise current man-made contamination of shallow groundwater in Utah. Very little has been published on the subject, and most of the information was obtained by personal observation and through interviews of individuals concerned with water quality protection in Utah. After presenting the relevant physiographic, geologic, and hydrologic characteristics of the various regions of Utah and discussing how these relate to groundwater contamination in general, representative groundwater quality hazards in 32 sites or regions in Utah are presented. A very wide range of hazards to groundwater quality was found to exist. These cases cover the range …


Bulletin 3929 - Irrigation In Western Australia, K S. Cole Dec 1980

Bulletin 3929 - Irrigation In Western Australia, K S. Cole

Bulletins - 3000 - 3999

Irrigation is essential in many parts of the world to produce essential food and profitable cash crops. Generally, those areas of land with less than 360 mm of rain spread over a distinct wet season of several months cannot grow crops for food or cash on rainfall alone. Then irrigation becomes necessary unless some peculiarity such as an oasis exists.


Ute Self-Determination In Setting Tribal Resource Development Policy, Herbert H. Fullerton, Mac Mckee, Roger D. Hansen Jul 1980

Ute Self-Determination In Setting Tribal Resource Development Policy, Herbert H. Fullerton, Mac Mckee, Roger D. Hansen

Reports

The Ute Indian Tribe of northeastern Utah has large land holdings rich in water and energy resources. Revenues from these sources have created capital that can potentially be used by the Tribe to further develop its resources and expand its agricultural and business enterprises. Realities, however, complicate this simple scenario in that the Tribal goals are broader than pure economic gain and that increased incomes may mean sacrifices in terms of these other goals. The Tribe faces the problem of how best to develop its water resources in a way that best meets its multiplicity of needs.

Evaluation Of Possible Temperature Fluctuations From Proposed Power Modifications At Hoover Dam, Larry J. Paulson, John R. Baker, U.S. Water And Power Resources Service Mar 1980

Evaluation Of Possible Temperature Fluctuations From Proposed Power Modifications At Hoover Dam, Larry J. Paulson, John R. Baker, U.S. Water And Power Resources Service

Publications (WR)

There are several planned alternatives for increasing the generation capacity of Hoover Dam to help meet peak power demands. These alternatives include: (a) uprating the existing generating units, (b) replacing or adding one or more generating units and (c) adding reversible pumped-storage hydroelectric units. Since the existing generators are at the end of their economic life and have to be replaced, their uprating has been scheduled as routine maintenance. This will increase the generating capacity of the Hoover Dam powerplant from 1240 MW to 1810 MW, but the anticipated capacity for meeting power demand is 2300 MW. Therefore, modifications (alternatives …


Evaluation Of Impacts Associated With Reregulation Of Water Levels In Lake Mohave, Larry J. Paulson, John R. Baker, U.S. Water And Power Resources Service Mar 1980

Evaluation Of Impacts Associated With Reregulation Of Water Levels In Lake Mohave, Larry J. Paulson, John R. Baker, U.S. Water And Power Resources Service

Publications (WR)

The U.S. Water and Power Resources Service is considering reregulating Lake Mohave water levels to increase the net power benefit from Hoover Dam. Reregulation will not increase the generation capacity of the Hoover powerplant but it will enable the plant operation to be increased when the energy has greater monetary value. Energy generated at different times of the year has different market value, the highest being in January-March and July- September. By generating more power during these periods more net monetary benefit can be derived from Hoover Dam. The total volume of water released from Hoover Dam over an annual …

Publications (WR)

The ever-increasing demand for energy in the southwest has led to a search for additional sources of power generation. Coal-fired powerplants currently provide most of the baseline energy in the southwest, but this must be supplemented with hydroelectric power during periods of peak demand. In order to provide additional peaking power, the U.S. Bureau of Reclamation is considering a number of projects to modify existing hydroelectric facilities, or add new facilities in the Lake Mead Recreation Area. The Hoover Powerplant Modification Feasibility Investigation was authorized by Congress on December 16, 1975 to determine the feasibility of: (i) adding one or …

Evaluation Of Livestock Runoff As A Source Of Water Pollution In Northern Utah, Stephen T. Wieneke, Dennis B. George, Daniel S. Filip, Brad Finney

Reports

A mathematical model was developed to predict the impact of dairy and beef cattle feedlot runoff on receiving streams. The mathematical expressions used in the model describing runoff quantity and quality were not only a function of single rain or snow precipitation events but also consecutive events prior to the runoff occurrence. The runoff quantity and quality were also a function of feedlot surface. Computer simualtions indicate that pollutants from feedlot runoff may have a significant impact on receiving streams during winter months. Runoff from feedlots located within the study area, however, had little impact on water quality in the …

Evaluation Of Particular Mulches As Plant Growth Media And Erosion Inhibitors, C. Earl Israelson, William F. Campbell, Eugene K. Israelsen, Ronald V. Canfield, David Ianson

Reports

Introduction: Increasing public awareness of the desireability of protecting the environment from soil erosion caused by wind and water has centered attention on large construction projects such as highways and housing subdivisions, as well as on individual building sites and parking lots. If unattended, sediment produced from these areas pollutes surface water, restricts drainage, fills reservoirs, damages adjacent land, and upsets the natual ecology of lakes and streams. The search continues for products and practices that will prevent or lessen the amount of sediment leaving construction sites. Products currently in use include chemical as well as organic materials, and they …

Management Of Rural Domestic Water Systems In Utah, Trevor C. Hughes Jan 1980

Management Of Rural Domestic Water Systems In Utah, Trevor C. Hughes

Reports

Introduction: There are now more than 400 community type public drinking water systems in Utah. Considerable state and federal assistance is available for construction or renovation of such systems, but once the system is constructed and the consulting engineer leaves, the managers of the smaller systems find themselves quite isolated from sources of professional assistance. The larger systems have a revenue base which can provide ongoing services of a consultant or salaried engineer and well trained operators. The smaller systems, particularly low density rural systems where the length of pipeline per user is very high, usually find themselves barely able …

Management Of The Hydrologic System In Areas Subject To Coal Mining Activities, Rollin H. Hotchkiss, Eugene K. Israelsen, J. Paul Riley Jan 1980

Management Of The Hydrologic System In Areas Subject To Coal Mining Activities, Rollin H. Hotchkiss, Eugene K. Israelsen, J. Paul Riley

Reports

Publicity given to the detrimental effects of mining activities on the environment has tended to overshadow somewhat the hydrologic opportunities and benfits that could be associated with these activities. For example, many areas disturbed by surface mining have proved to be excellent recharge areas for groundwater aquifers. The degree to which mine sites can be exploited to improve management of the hydrologic system depends on both the local geology and the mining techniques used. The report examines the effects of present mining activities on the associated hydrology system, and identifies specific mining procedures and management techniques which not only minimize …

A Preliminary Study On Expanding And Financing State Water Development, Daniel H. Hoggan, Kirk R. Kimball, Jay M. Bagley

Reports

The effects of recent energy price increases, domestic inflation rates, financial market fluctuations, and changing public attitudes toward federally sponsored water resource development and management have brought economic and financial consideratiosn to the forefront of Western water management issues. Recently enacted federal policies place increased responsibility on the states and localities for the development and management of their water resources. A response common to many of the western states has been to stengthen traditional, and often small, water financing and development programs. In creating and sustaining such a posture, however, state governments must address the important questions pertaining to the …

Development Of Procedures To Evaluate Salinity Management Strategies In Irrigation Return Flows, V. A. Narasimhan, A. Leon Huber, J. Paul Riley, J. J. Jurinak Jan 1980

Development Of Procedures To Evaluate Salinity Management Strategies In Irrigation Return Flows, V. A. Narasimhan, A. Leon Huber, J. Paul Riley, J. J. Jurinak

Reports

The salinity added irrigation return flows is a major problem in rivers draining agricultural lands throughout the arid regions of the world, and many irrigation water management alternatives have been proposed for reducing downstream salinity problems. The merits of these alternatives, however, can only be judged from reliable information on their actual effects on the salinity in rivers receiving the drainage water and the water withdrawn from the river by downstream users. Hydrosalinity models are widely used to estimate these effects to guide the selection of a policy on management of irrigation return flows. The purpose of this research was …

Water Demand At Recreation Developments, Simon Lam, Trevor C. Hughes Jan 1980

Water Demand At Recreation Developments, Simon Lam, Trevor C. Hughes

Reports

Design criteria for drinking water systems at recreation developments, particularly summer home type, cause frequent confrontations with regulatory agencies. Developers claim extremely low water use rates due to low occupancy rates, but regulatory agencies are concerned about changes over time from essentially weekend use to more permanent residency and also about occasional peak day water demands similar to those of municipal systems. Little empirical data have been available to resolve such questions. This study included the gathering and analysis of both historic water use measurements and additional daily and instantaneous measurements during peak seasons at 11 Utah and one Wyoming …

Use Of Extreme Value Theory In Estimating Flood Peaks From Mixed Populations, Ronand V. Canfield, D. R. Olsen, R. H. Hawkins, T. L. Chen Jan 1980

Use Of Extreme Value Theory In Estimating Flood Peaks From Mixed Populations, Ronand V. Canfield, D. R. Olsen, R. H. Hawkins, T. L. Chen

Reports

The flood magnitude for a given frequency or return period is estimated by fitting a probability distribution to the historical annual flood series. The log-Pearson type III distribution has been selected by the Water Resources Council for general use by the federal government, but practitioners should examine an annual flood series and use alternative distributions where they will produce better estimates. Empirical goodness of fit is one criterion for choosing a distribution, but the reasonableness of the assumptions theoretically associated with the form of the distribution should also be considered. In theory, extreme-value distributions are particularly applicable to flow series …
