Economic Impacts Of Two Proposed Power Plants On Utah's Irrigated Agriculture, Rangesan Narayanan

Reports

Introduction: The impact on agriculture of a large coal-fired stream electic plant (such as the proposed Intermountain Power Project near Lynndyl, Utah) or a large nuclear electic plant (such as proposed for the Green River Site near Emery, Utah) depends on a large number of factors. Among the most important are the technology used in power plant design, the site-characteristics of the plant location, the availability of water resources in the vicinity of the plant, the quality of the available water, and the types of agricultural uses and their water requirements. Some of these factors can be defined by obtaining …

Evaluation And Comparison Of Overland Flow And Slow Rate Systems To Upgrade Secondary Wastewater Lagoon Effluent, Michael C. Kemp, Daniel S. Filip, Dennis B. George

Reports

To evaluate the effectiveness of overland flow treatment in upgrading secondary wastewater lagoon effluent, three 15 x 36 m plots on a 2.5 percent slope were constructed and sown for a high density vegetative cover using Reed Canary grass. Wastewater was applied to the upper end of each plot at rates of 7.5, 15, and 22.5 cm/wk. Results from the overland flow system investigation were compared with similar data obtained the preceding year from an existing slow rate land application system on an adjacent site. Secondary effluent from the same lagoon system was applied to the slow rate system study …

The Impact Of Energy Resource Development Of Water Resource Allocations, John E. Keith, K. S. Turna, Sumol Padunchai, Rangesan Narayanan

Reports

This research used a linear programming model of the agricultural and energy sectors of Utah to examine the economically efficient allocation of water between agriculture and energy. Data were collected for agricultural returns, costs, and water requirements; energy returns, costs, and water requirements; and water supply costs. Results indicate that if large scale energy development occurs in the Colorado River Basin in Utah, most of irrigated agriculture will be eliminated, given Utah’s consumptive use constraint under the Upper Colorado Rive Compact. On the other hand, for two more “probable” levels of energy development, including the Energy Research and Development Administration’s …

Two drought indices are developed to achieve the overall objective of the study: (1) the drought severity …

Feasibility Of Accelerating Construction Of The Central Utah Project, Trevor C. Hughes, L. Douglas James, Frank Haws, C. Earl Israelsen

Reports

Introduction: Objective: In April, 1977 the President's statement on water projects recommended that a number of federal water development projects, including the Conneville unit of the Central Utah Project, not be completed. The ensuing efforts of project supporters brought about a review of the projected costs, benefits, and other political, social and environmental factors and consequently, the current issue is not whether or not the project should be constructed. Rather, the objective of this report is to examine the following question: Given the fact that at least the 5 units of the CUP which have already been authorized will eventually …

Utah's 1977 Drought, Trevor C. Hughes, Clark Bigler, Jerry Olds, Richard Griffin, Arlo Richardson, L. Douglas James, Norris Stenquist, James Harvey

Reports

The Utah Drought of 1976-1977 has been characterized as the wettest drought in history. It was produced by the driest winter season of record followed by summer rains which were much wetter than normal in many regions of the state. Stream-flow is highly correlated with winter rather than summer precipitation and therefore the most severe impacts of the drought were related to the record low stream-flow during 1977 plus the ski industry impacts which were directly related to 1976-1977 snowfall. Drought impacts upon several sectors of the economy plus the extensive responses of all levels of government in the form …

The Great Basin Climate Study For Range Fire Management, Kenneth G. Hubbard, Joel E. Fletcher

Reports

The BLM (Bureau of Land Management) fire management personnel routinely use a fire danger computer program to estimate the effects of recent weather upon the fire hazard on the BLM rangeland sites. The program used for this purpose is the National Fire Danger Rating System (NFDRS) which was developed by the National Forest Service (Deeming, 1978). The NFDRS was used in conjunction with fire weather stations in the Great Basin for the dual purposes of evaluating the ability of NFDRS to predict fire danger and of determining the effectiveness of the present fire station network in detecting fire weather on …

Research On Increased Precipitation By Cloud Seeding: Development Phase, Geoffrey E. Hill

Reports

Development of several instrumentation systems for measuring atmospheric variables related to winter orogaraphic cloud seeding was undertaken. A heated tipping bucket precipitation gage was modified both for reliable use and accuracy of data. A solid state memory device was also developed at UWRL for this project. A parachute dropsonde for measuring vertical air motion was further developed. In addition, instrumentation was placed on board an aircraft for measuring concentrations of super cooled water, ice nuclei, and ice crystals. Airborne measurements during cloud seeding with silver iodide showed that the plumes of seeding material could be detected over a target area, …

Water Quality Analysis Laboratory Procedures Syllabus, P. A. Cowan, D. B. Porcella, V. D. Adams, L. A. Gardner

Reports

Introduction: The 1976 edition of "Methods of Chemical Analysis of Water and Wastes" describes chemical analytical procedures to be sued in Water Quality Office (WQO) laboratoires. The methods were chose through the combined efforts of the Regional Analytical Quality Control (AQC) Coordinators, Laboratory Quality Control Officers, and other senior chemicsts in both federal and state laboratories. Method selection was based on the following criteria: 1. The method should measure the desired constitutent with precision and accuracy suffiecient to meet the data needs of WQO in the presence of the interferences normally encountered in polluted waters. 2. The procedures should utilize …

Hydraulic Characteristics Of Pvc Pipe In Sanitary Sewers (A Report Of Field Measurements), Ronald R. Bishop

Reports

Introduction: Since pipe made of poly vinyl chloride (PVC) is relatively new, its hydraulic characteristics that cause fluid friction head loss are not as well known as those of cast iron and concrete pipe. The lack of universally accepted roughness parameters for PVC pipe is attested by the fact that most textbooks dealing with the hydraulics and the fluid mechanics do not include such values. The hydraulic characteristics of PVC pipe have been measured in the laboratory studies for both open channel flow conditions, Neale and price (1), and for full flow conditions, Jeppson (2). However, no studies are known …

Salinity Management Options For The Colorado River. Damage Estimates And Control Program Impacts, F. Bruce Brown, Joel R. Cannon, Ralph C. D'Arge, Larry Eubanks, W. T. Franklin, Charles W. Howe, Ernest B. Jackson, K. L. Leathers, Frank E. Robinson, Don Snyder, Jeffrey T. Young, Robert A. Young

Reports

Rivers draining arid basins increase in salinity content in the downstream area to the point where water users are often significantly damaged. The problem in some cases can be ameliorated by altering upstream water and land use practices. An economic trade off exists between the cost of such upstream efforts and the downstream benefits achieved. This report examines options for salinity management in the Colorado River Basin. The study sought to provide additional information to estimate 1) economic damages caused by various salt concentrations to agricultural and municipal water users and 2) economic costs of salinity control measures by upstream …

Loads On Box Culverts Under High Embankments: Analysis And Design Considerations, David L. Allen, Rick L. Russ

Kentucky Transportation Center Research Report

Pressure and design analyses of five reinforced concrete box culverts are presented. Three of the culverts were constructed with the imperfect trench. Measured pressures on the culverts are compared to pressures predicted by the theories of Marston, Spangler, and Castes. Also, comparisons are made between measured pressures and calculated design pressures using AASHTO's Standard Specifications for Highway Bridges, 1.2.2(A). It is noted that the imperfect trench is, apparently, effective in reducing pressures on the top slab. The AASHTO design formulas underestimated the pressure on the top slab of the culverts without the imperfect trench.

Seatbelt Usage In Kentucky [Jan. 1978], Kenneth R. Agent, Michael Barclay

Kentucky Transportation Center Research Report

In this report, the effectiveness and usage of seatbelts by Kentucky motorists and factors affecting usage are examined and identified. Data were obtained from three sources: field observations, accident reports, and a questionnaire.

Kentucky drivers and passengers were found to have lower seatbelt usage rates (slightly under 10 percent) than drivers and passengers in other states. The accident data showed that the chances of being killed or severely injured is greatly reduced by wearing a seatbelt. Seatbelts reduced the chance of being killed by a factor of six and the chance of being severely injured by a factor of two. …
