An Economic Evaluation Of Benefits And Costs Of Maintaining Instream Flows, Rangesan Narayanan, Dean T. Larson, A. Bruce Bishop, Parvaneh Amirfathi

Reports

Instream flows enhance recreation, hydropower, fish and wildlife maintenance, and riverine ecosytems. Each use has water requirements that vary over time in unique patterns. The determination of the overall instream requirement at any given time must be considered in competition with the demand for municipal and agricultural uses. Two obstacles to integrating instream uses into the appropriation system of water law are difficulty in satisfying the legal requirements of an appropriation for a public use and the fact that instream flow uses are considered more "environmental" than "economic" in character. The extreme options for allocating flow between these user groups …

Drought Management Concepts: Lessons Of The 1976-1977 U.S. Drought, Rangesan Narayanan, Herbert H. Fullerton, Trevor C. Hughes, A. Bruce Bishop, Mac Mckee, Dean T. Larson, Hamid Fakhraei

Reports

Three approaches to drought management are developed as generalized mathematical models. Each model is then applied to particular locations in Utah using the hydrologic/economic data from the 1976-77 drought. The modeling approaches include: (1) A multiple regression approach is used to quantify the changes in water use achieved by three common municipal sector rationing policies: (a) restrictions on time of outdoor use, (b) price increases, and (c) mandatory quantity restrictions (2) A model was presented for determing the optimal long term price schedule for rationing a stochastically variable water supply during summer peak demand season among groups of municipal water …

Alteration Of Availability Of Heavy Metals To Aquatic Microflora By Complexation With Organics Associated With Oil Shale Development, Bruce S. Mok, Jay J. Messer

Reports

Leachates from both raw (unretorted) and Paraho retorted oil shale show the ability to bind copper, and perhaps cadmium, strongly enough to mitigate the inhibitory effects of these metals on the growth of the test algal,

Reconnaissance Of Sediment-Phosphorus Relationships In Some Utah Reservoirs, Jay J. Messer, Jean M. Ihnat

Reports

Introduction: Phosphorus inputs to lakes and reservoirs from tributary streams and non-point sources are well-known contributors to nuisance algal growths that degrade water quality for potable and recreational uses in lakes and reservoirs. However, phosphours inputs to the euphotic zone may also occur from within the lake itself, as a result of releases from both oxic and anoxid sediments. Such releases may originate from phosphorus inputs to a lake or reservoir during high runoff periods in the previous winder or spring, or they may represent phosphorus trapped in the sediment many years earlier, when phosphorus contributions from natural or anthropogenic …

Polycyclic Aromatic Hydrocarbons: Are They A Problem In Processed Oil Shales?, David L. Maase, V. Dean Adams

Reports

Organic residues from processed oil shales were characterisized with specific attention to polycyclic aromatic hydrocarbons (PAH). Oil shale development in the White River Basin (Utah and Colorado) was projected and hydrological and geological parameters pertinent to estimations of polycyclic aromatic hydrocarbons (PAH) flux were focused. Oil shale samples from the Union B, Paraho, and Tosco II processes were extracted by using organic solvents in a soxhlet apparatus and by mixing shale samples with water (characterization in

Adapting Water Services To Urban Growth: A Case Study Of Salt Lake County, Dean T. Larson, Kirk R. Kimball, Calvin W. Hiibner, Jay M. Bagley

Reports

Urbanizing areas thorughout the nation are considering governmental reorganization or consolidation to coordinate planning and improve the cost effectiveness of the delivery of public services. More efficient water supply and wastewater services may become important in the political debate over reorganization. However water factors figure politically, accomplished reorganizations must carefully plan for efficent provision of water services. This study profiles the structure and interactions of municipalities and water service agencies in Utah's Salt Lake County during the 1970s. Both 1975 and 1978 attempts to consolidate Salt Lake City and the unincorporated areas of the county failed. The voting patterns, interest …

Adapting Appropriation Water Law To Accommodate Equitable Consideration Of Instream Flow Uses, Jay M. Bagley, Dean T. Larson, Lee Kapaloski

Reports

The increasing public interest in naturally flowing streams has fostered efforts to obtain their protection under existing state water laws. In this study, the water laws of Arizona, Colorado, Idaho, Montana, Nevada, New Mexico, Utah, and Wyoming were examined and compared 1) with each other, and 2) against a set of aleitn criteria, to assess shortcomings in accommodating instream flow protections. It was determined that the appropriation system has the essential features of and ambodies legal principles that should allow the accommodation of instream flow values but, at this time, purchase of existing rights or the exercise of governmental reservation/withdrawal/appropriation …

Impediments To Effective Interactions Between Multipurpose Water Districts And Other Governmental Institutions In Urbanizing Areas, Jay M. Bagley, Frank W. Haws, Wendell B. Anderson, Daniel H. Hoggan, Lee Kapaloski

Reports

Water institutions are highly diffused throughout society. These institutions interact with one another in various ways. As water needs and services expand, collaborative and cooperative arrangements are commonly sought as a means of meeting common goals of providing a safe, dependable adn least cost water supply to particular constituencies. Of the many different institutions involved in the development, managment, distribution, and use of water, perhaps the most significant in terms of extensive interactions with other institutions is the kind that is typified by Water Conservancy Districts and Metropolitan Water Districts in Utah. The statutory and operating framework of counterpart organizations …

Some Lake Level Control Alternatives For The Great Salt Lake, Marvin E. Allen, Ronald K. Christensen, J. Paul Riley

Reports

Fluctuations of the level of the Great Salt Lake cause large changes in both surface area and shoreline. Developments adjacent to the lake have been damaged by both high and low lake levels; and unless measures are implemented to regulate lake level fluctuations or otherwise to protect these developments, damages will continue. Various possible managment alternatives for mitigating potential damages from lake level fluctuations need to be examined and evaluated. In this study, three possible techniques are examined for reducing damages from fluctuating water levels at the lake, namely: 1. Consumptively using an increased proportion of the inflowing fresh waters …

Hydrologic Evaluation Of The Coastal Belt Water Project Sarir And Tazerbo Well Fields, Libya, Edward P. Fisk, Christopher J. Duffy, Calvin G. Clyde, Roland W. Jeppson, Phillip H. Degroot, Bhasker Rao K., Win-Kai Liu

Reports

Executive Summary: The basic purpose of this study was to conduct a finite-element computer model and give an dindependent appraisal of the reliability of the groundwater supply for the proposed Coastal Belt Water Project (CBWP_ Well Fields at Sarir and Tazerbo. There is no doubt that ample quantities of groundwater of acceptable quality occur at the sites selected for these well fields for the estimated 50-year life of the project and longer. Of major concern is the predicted drawdown of wells and total pumping lifts throughout the 50-year period. Excessive drawdowns could cause operating costs to become prohibitibely expensive. Average …

Stability Analysis Of Closed Surge Tanks By Phase-Plane Method, Mostafa A. Sabbah

Civil & Environmental Engineering Theses & Dissertations

The governing equations describing water level oscillations in a closed surge tank with compressed air at the top of the tank are a set of nonlinear ordinary differential equations if the hydraulic system is analyzed as a lumped system. These oscillations are stable or unstable depending on the parameters of the plant and the type and magnitude of the disturbance.

The present available stability criterion has been developed by linearizing the governing equations and is, therefore, valid only for small disturbances.

In the research reported herein, the governing equations are normalized to reduce the number of parameters from nine to …

A Study Of Single Angle Compression Members, James Robert Callaway

Dissertations and Theses

A study was undertaken to investigate the compressive capacity of a specific group of single angle members.

A review of existing literature and techniques was presented. Laboratory compression tests were performed on 22 angle members of four different sizes and two different lengths. Additional tests were performed to determine the yield strength of the material. The results, normalized with respect to the yield stress, were tabulated and discussed.

Two existing analytic models were used to attempt to predict the ultimate capacity of the test members. The first, an elastic method, was based upon the AISC combined stress equation. The second, …

Strain Energy Analysis Of Pavement Designs For Heavy Trucks, Herbert F. Southgate, Robert C. Deen, Jesse G. Mayes

Kentucky Transportation Center Research Report

The first portion of this paper summarizes classical concepts of work, or strain energy, as applied to the analysis of stresses, strains, and deflections under various vehicular load configurations on pavement systems. Controlling equations for strain energy density are presented. When considering strain energy density, strain energy, or work, all components of stresses or strains must be taken into account so that total internal behavior can be evaluated. Previously, pavement thickness design systems have been developed using only a single component of strain, typically at the bottom of the asphaltic concrete layer or at the top of the subgrade. Strain …

Nonlinear Analysis Of Shear Walls And Shear Panels By Finite Element Method, Erhan Atay

Theses

The objective of this work was to determine the feasibility of applying the Finite Element Method to Nonlinear Analyses of Shear Walls and Shear Panels.

Various existing methods are reviewed and discussed.

These studies determined that the application of Finite Element Method to Nonlinear Analysis of Shear Walls and Shear Panels is being misused in many cases but is very practical and promising where justified. However more studies are needed for the manner of modeling to be used to connect the wall to beam and slab elements that frame into that wall. To model the coupled beams as plane stress …

Comparison Of Steady-State Pipe Network Computer Programs, Michael Bernice Holloway

Civil & Environmental Engineering Theses & Dissertations

Four widely used computer programs for the analysis of steady state flows in pipe networks are compared. These programs are NEWTH, written by Jeppson; KENTUCKY, written by Wood; FLOW, written by Epp and Fowler; and LIQSS, written by Stoner. Differences, similarities, advantages and disadvantages of these programs, and various options available are discussed for the benefit of possible future users. In addition, the efficiency of NEWTH, KENTUCKY, and FLOW was tested by simulating a typical network by each program. The listing of LIQSS was not available, and thus was not included in this comparison. In simulation, KENTUCKY used over twice …

Allocation Of Transportation Costs To Users, James E. Black, Jerry G. Pigman

Kentucky Transportation Center Research Report

The 1980 annual cost responsibility and user-generated revenue were determined for each vehicle class using Kentucky's highways. The incremental-cost method was selected as the procedure for assigning the responsibility for each component of the highway cost to the users. Generally, the method is based on the concept that each highway cost component can be subdivided into increments caused by vehicles of different types, sizes, and weights.

Annual costs for the highway system were based on construction, replacement or current value costs representing capital investment components of the highway. Those components were: 1) preliminary design and engineering, 2) right-of-way, 3) utilities …

Implementation Of Road Rater Deflection Testing For Pavement Evaluation And Overlay Design, Gary W. Sharpe, Herbert F. Southgate, Robert C. Deen

Kentucky Transportation Center Research Report

Road Rater deflection data were used to estimate the in-place subgrade strength and the in-place structural capacity of existing pavements. Pavement behavior can be expressed in terms of a reduced thickness of "reference" quality paving materials or as a reduced modulus of elasticity for the constructed thickness of asphaltic concrete. Mathematical relationships were developed making it possible to "program" the evaluation procedure (in modular form) for use with small hand calculators or minicomputers.

The pavement evaluation method has been successfully implemented in making recommendations for overlay designs for several pavement sections. Road Rater deflection data were used to estimate the …
