Powers Of The State Of Kentucky In Implementing An Effluent Tax As A Part Of An Interstate Ohio River Basin Water Pollution Control Program, Anita L. Morse, Edward Zeigler

KWRRI Research Reports

This report is intended to set forth some of the problems and solutions involved in financing and regulating water quality control. The purpose is to record some of the major problems confronting those who legislate water quality, those who espouse technological answers, and those who see the problem in terms of economic solutions. The limits placed by political and institutional constraints on solutions to these problems are frequently not understandable.

Within this report are contained separate investigations: a study of federal-interstate relations and the interstate compact; a study of Kentucky's common law approach to water rights; a study of financing …

A Rock Classification Schema, Robert C. Deen, C. D. Tockstein, M. W. Palmer

Kentucky Transportation Center Research Report

The need for engineering data on earth materials for use in site selection, design, construction, and maintenance of major engineering structures is generally accepted. Probably the most pressing need is for such data to use in preliminary considerations of site selection and design alternatives. Maps and(or) surveys giving the areal distribution of earth materials and their characteristics, together with topographic maps available for many areas, would permit much preliminary work on engineering structures to be done without the engineer ever having to leave his office.

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 …

Spatially Varied Subcritical And Supercritical Flow In Gullies, T. Y. Kao

KWRRI Research Reports

The objective of this study was to investigate the phenomena of subcritical and supercritical spatially varied flow in rectangular expansions such as that in an erosion gully. Based on momentum and continuity principles, equations were developed to predict such flow phenomena. Computations of the water surface profiles for subcritical spatially varied flow were carried out by applying direct step numerical calculations. Because of the presence of standing waves, the method of characteristics was employed in the analytical analysis of the supercritical flow phenomena. Of primary importance in this study is the effect of varying amounts of lateral inflow rates. Other …

High-Intensity Reflective Materials For Signs, Rolands L. Rizenbergs

Kentucky Transportation Center Research Report

Field observations and laboratory tests and evaluations were conducted on High-Intensity and Engineering Grade materials (Scotchlite), manufactured by the Minnesota Mining and Manufacturing Company, and were compared in regard to reflectivity, durability, and cost.

The High-Intensity Grade materials were found to have outstanding performance characteristics in comparison to Engineering Grade materials. The material significantly enhances sign legibility under low-beam illumination, and accelerated weathering tests showed superior durability.

"Before" Evaluation Of Economic Growth Center Developmental Highway (Ky 55, Campbellsville-Lebanon), Joseph T. Farmer, Jerry G. Pigman

Kentucky Transportation Center Research Report

Before-and-after impact studies were selected as the means of determining the effect of reconstructing a 4.813-mile (7.744-kilometer) section of KY 55 between Campbellsville and Lebanon. The area, though still depressed in terms of per capita income and employment, has many resources available for growth. The study area is predominantly an agriculturally-oriented economy. However, manufacturing employment has increased in recent years, mainly because of industrial sites made available by local industrial commissions.

Overall, social services appear to be adequate and very near statewide averages. Recreational facilities are not highly developed and are primarily of the summer outdoor type.

Reconstruction of KY …

Acoustic Emission Testing Of Shielded Metal-Arc Welds Using Astm A 36 Steel, Theodore Hopwood Ii

Kentucky Transportation Center Research Report

Manual, shielded metal-arc welds on ASTM A 36 structural steel were monitored with acoustic emission equipment. The listening device detected operator inconsistencies and improper electrode deposition during the welding operation. On completion of the weld, acoustic emission monitoring detected slag inclusions, cracking, and martensite formation.

Identification Of Hazardous Locations On Rural Highways In Kentucky, Charles V. Zegeer

Kentucky Transportation Center Research Report

The purpose of this study was to determine the most effective method of identifying hazardous locations for on-site investigations. To decrease the possible effect of random or spurious accidents on the identification of hazardous locations, a 0.3-mile (0.48-km) segment was chosen along with 1- and 2-year periods for accumulating and comparing accident data. An optimal method for identifying hazardous locations and sections was determined to be one which (1) maximizes benefits from improvements, (2) identifies locations with critically high accident rates, and (3) identifies potential hazards. A sample of 170 locations was used to compare several location-identification methods. The procedure …

Laboratory Simulation Of Rainfall Erosivity For Gully Formation Study, T. Y. Kao

KWRRI Research Reports

The objective of this study was to develop a rainfall simulator, which imparts to the laboratory rainfall the more important characteristics of natural rainfall such as intensity, drop spectrum, kinetic energy, and momentum at impact, for using in soil erosion research with better results. In developing this simulator the better features of the basic types of earlier simulators, drip and nozzle, have been incorporated into this single design. The simulator developed in this study consists of a number of individual box modules placed in a rectangular pattern to form a single unit. Each module has a grid of capillary holes …

"Before" Evaluation Of Economic Growth Center Developmental Highway (Us 25e: Corbin-Barbourville), Joseph T. Farmer, Jerry G. Pigman

Kentucky Transportation Center Research Report

Before-and-after impact studies were selected as the means of determining the effect of reconstructing a 4.886 mile (7.862 kilometer) section of US 25E between Corbin and Barbourville. A comprehensive analysis of the "before" statistics revealed the area designated as a potential growth center suffered from social and economic mediocrity. Many characteristics considered essential for economic prosperity are lacking. Per capita income and educational achievement levels are lower than statewide averages. Transportation is dependent upon highways and many existing routes provide a very low level of service.

On the other hand, the area has adequate industrial and recreational potential to insure …

A Rock Evaluation Schema For Transporting Planning In Kentucky, C. D. Tockstein, M. W. Palmer

Kentucky Transportation Center Research Report

The initial goal was to devise an engineering classification system for intact rock samples based on simple index tests which could be used to categorize Kentucky surface and near-surface rock types and assist Kentucky Department of Transportation personnel in planning for transportation facilities. While conducting the literature survey, several facts become apparent:

1. a large number of rock classification systems, geologic and technical, general and specific, already existed;
2. an equally large number of index tests had been devised; and
3. there was a lack of communication among those involved in specialized areas of rock-related work (geologists, civil engineers, mining engineers, etc.), and, …

Loads On Box Culverts Under High Embankments, Harry F. Girdler

Kentucky Transportation Center Research Report

The structural design of culverts requires a reliable estimate of the earth pressures which will come to bear on the structure during and after construction of the embankment. The actual bearing pressure at a given time and under various conditions of differential settlement may be greater or less than the deadload of the fill or embankment over the structure. This report describes the instrumentation and construction of three box culverts designed by the imperfect trench method. A total of 42 Carlson earth pressure cells were installed in conjunction with strain gages and settlement measuring devices, including inverted settlement plates and …

Seasonal Changes In Water Quality And Primary Productivity In Doe Valley Lake, Edmond J. Bacon, Stuart E. Neff

KWRRI Research Reports

Primary productivity and water quality were studied in Doe Valley Lake, a 147-hectare impoundment on Doe Run, a spring-fed stream in Meade County, Kentucky, from 13 June 1969 to 31 July 1972. Doe Valley Lake is monomictic during most winter seasons, but it is dimictic during more severe winters because of its morphometry and location on the borderline climatic region for dimictic lakes (37° N latitude). Oxygen depletion in the hypolimnion is severe, and anaerobic conditions usually prevail by late June. A hypolimnetic areal deficit of 0.038 mg/cm²/day was calculated. Supersaturation of oxygen in the epilimnion was common, …

Development Of Prediction Relationships For Water Requirements With Irrigation Cooling, Billy J. Barfield, John N. Walker, F. A. Payne

KWRRI Research Reports

A model for predicting leaf temperatures during an off-on mist cycle is presented. The model uses a combination of energy budget and aerodynamic techniques. The model was tested for dry leaf temperature and evapotranspiration predictions using average hourly data from Arizona. The accuracy was good. It was also tested for dry leaf temperature predictions using two to three minute data with a widely varying net radiation. When reasonable values of stomatal resistance were used, the agreement was again good.

The model was tested for prediction of wet leaf temperature prediction with a ten minute on, fifty minute off mist irrigation …

Changes In The Economy And Ecology At Proposed Lake Sites In The Salt River Basin, Kentucky, During Early Construction Of The Dam For Taylorsville Lake, Louis A. Krumholz, Stuart E. Neff, Edmond J. Bacon Jr., John R. Baker, Daryl E. Jennings, Andrew C. Miller, Vincent H. Resh, David S. White

KWRRI Research Reports

This is an extension of the work reported in Project numbers B-005-KY, B-016-KY, and B-022-KY that extended from 1 July 1968 through 30 June 1972. Permanent collecting stations have been established at 67 sites throughout the Salt River, Beech Fork, and Chaplin River drainages. Turbidities increases quickly as flow and runoff increase, and subside quickly when the rain stops. Suspended solids range up to 1,700 mg/l in high turbidities and vary considerably as a result of local spates. Water chemistry generally reflects the limestone nature of the substrate and physico-chemical characteristics of a typically healthy limestone stream. Bottom organisms are …

Sensitivity Of Vertebrate Embryos To Heavy Metals As A Criterion Of Water Quality, Phase I, Wesley J. Birge, John J. Just, Albert G. Westerman, A. Duane Rose

KWRRI Research Reports

Avian, amphibian and fish embryos were given continuous treatment with inorganic mercury, methyl mercury, cadmium and lead, to determine the sensitivity of embryogenesis to metallic poisoning. All metals produced substantial degrees of lethality and/or gross anatomical anomalies at 10 ppb or less. Treatment with inorganic mercury at 10 ppb produced 100% kill of frog embryos. Chick and rainbow trout embryos suffered 10-20% lethality when exposed to 1 ppb of either inorganic or methyl mercury. Lead and cadmium at 1 ppb produced 24-32% lethality in chick embryos. No significant differences were observed in the embryopathic effects of inorganic or methyl mercury. …

Porous Sand-Asphalt Mixtures, James H. Havens

Kentucky Transportation Center Research Report

Size is relative. Densely graded sand-asphalts are relatively similar to conventional, bituminous concretes. Porous sand-asphalts possess the same attributes as other porous, bituminous mixtures. Surely, sand-asphalt mixtures, can be designed to be as porous as the so-called, open-graded plantmix seals. Particle shape and texture otherwise define skid-resistance. Stability remains an assurance against scaling. Stability is assured by maximum utilization of filler-bitumen ratio and the stiffness of asphalt cement.

Recommendations For Implementation Of Uniform Project Identification From The Upi Task Force, Herbert F. Southgate

Kentucky Transportation Center Research Report

For years project identifications have been based upon county, section, subsection, and phase of work. While this system worked well in the beginning, overlay constructions, widening efforts, etc. have caused overlapping of projects to the point that identification of a given portion of a highway has become very difficult. Furthermore, each of the many separate phases of work has its own project number and may not be so readily identifiable as the succeeding work phase.

Management came to realize there was a need for a numbering identification system that would be readily understandable. The direct result was the development of …
