Optimal Systems Of Storm Water Detention Basins In Urban Areas, D. K. Mynear, C. T. Haan

KWRRI Research Reports

Flood retention basins are commonly used in urban areas to reduce the impact of urbanization on downstream flooding. When more than a few acres are developed, systems of retention basins are often required. A procedure has been developed whereby the optimum (least cost) system of basins can be determined to meet a given downstream flow requirement. The method considers several design options including basins on all subwatersheds, basins on only some of the subwatersheds, basins of various sizes and basins with various stage-discharge characteristics. The procedure has been developed in the form of a computer program to aid the designer …

Simulation Of The Sedimentology Of Sediment Detention Basins, A. J. Ward, C. T. Haan, B. J. Barfield

KWRRI Research Reports

Sediment detention basins are a widely used means of controlling downstream sediment pollution resulting from stripmining and construction activities. A mathematical model for describing the sedimentation characteristics of detention basins has been developed. This model requires as inputs the inflow hydrograph, inflow sediment graph, sediment particle size distribution, detention basin stage-area relationship and detention basin stage-discharge relationship. Based on this information the model routes the water and sediment through the basin. In this routing process the outflow sediment concentration graph, the pattern of sediment deposition in the basin and the sediment trapping efficiency are estimated. Comparison of predicted results with …

Alfalfa Response To Varying Rates Of Phosphorus And Potassium Fertilization On Deep, Red, Limestone - Derived Soils Of The Pennyroyal Area In Kentucky, H. C. Vaught, Kenneth L. Wells, K. L. Driskill

Agronomy Notes

The Western Pennyroyal area of Kentucky consists largely of deep, well-drained limestone-derived soils occurring on an undulating to rolling landscape. A thin loess mantle overlies the limestone residuum in many areas. Soils on these landscapes are capable of good crop production, providing the basis of the rather intensive grain-hay- tobacco-livestock farming systems common to the Pennyroyal area. Because of the well-suited physical characteristics of these soils, alfalfa is a very important hay crop to this area.

Effectiveness Of Green-Extension Systems At High-Speed Intersections, Charles V. Zegeer

Kentucky Transportation Center Research Report

The purpose of this study was to determine the effectiveness of green-extension systems (GES) for reducing the dilemma-zone problem associated with the amber phase of traffic signals at high-speed intersections. Reactions of 2,100 drivers were noted during the amber phase at nine intersections, and the dilemma-zone distances with respect to the stop bar were determined.

Before-and-after studies made at three green-extension sites showed a 54-percent reduction in total accidents and a 75-percent reduction in rear-end accidents after GES installation. Accident severity was unaffected.

Conflict, volume, delay, and speed data were taken before and after GES installation at two sites. A …

Southern Regional Beef Cow-Calf Handbook: Hay Feeding Systems, Garry D. Lacefield, J. Kenneth Evans, Joe Burns

Agriculture and Natural Resources Publications

Forages (pasture, hay and silage) constitute the most feed consumed by beef cattle. The most convenient approach in producing feed is to provide quality pastures during as much of the year as possible and permit animals to graze growing forage to the maximum. To provide a year-round feed supply, however, one must usually rely on stored feed when growth is inadequate to meet animal needs.

Hay is the most common source of stored feed used in most beef cattle operations. Nutrients provided in hay harvested at the proper stage of plant growth and undamaged by weather usually cost less to …

Hydrology And Water Quality In The Central Kentucky Karst: Phase 1, James F. Quinlan, Donald R. Rowe

KWRRI Research Reports

Study of springs and cave streams has shown that heavy metal-rich effluent from a wastewater treatment plant can be traced to Hidden River Cave (beneath the city of Horse Cave) and thence 4 to 5 miles north to a group of 39 springs at 14 locations along a 5-mile reach of Green River. Nickel, chromium, copper and zinc in these effluent-bearing springs are in concentrations of as much as 30 times greater than other springs upstream and downstream from this reach, 20 times greater than the Green River, and 60 times greater than in shallow domestic wells between Horse Cave …

Effects Of Stream Channel Improvements On Downstream Floods, Yang H. Huang, Ronald K. Gaynor

KWRRI Research Reports

This report presents a self-calibrating watershed model for predicting the effect of channel improvements on downstream floods. The model is called MOPSET because it is a modified version of OPSET developed several years ago at the University of Kentucky. OPSET is a computerized procedure for determining an optimum set of parameter values by matching synthesized flows with recorded flows. Major modifications include the replacement of the modified Muskingum method of channel routing by a kinematic finite difference method, the division of the watershed into a number of segments, and the inclusion of a storage routing procedure to take care of …

Embryopathic Effects Of Waterborne And Sediment-Accumulated Cadmium, Mercury And Zinc On Reproduction And Survival Of Fish And Amphibian Populations In Kentucky, Wesley J. Birge, Jeffrey A. Black, Albert G. Westerman, Paul C. Francis, Jarvis E. Hudson

KWRRI Research Reports

Fish and amphibian egg cultures were used to determine the embryopathic effects of cadmium, mercury, and zinc released from natural and metal-enriched sediments, and to develop egg culture bioassay procedures suitable for monitoring bottom sediments for hazardous contaminants. Eggs of the narrow-mouthed toad (Gastrophryne carolinensis), goldfish (Carassius auratus), and rainbow trout (Salmo gairdnei) were cultured in contaminant-free water added to natural and metal-enriched sediments. Exposure was initiated after fertilization (toad, goldfish) or at 10 days prehatching (trout) and maintained continuously through 4-10 days posthatching. Sediments were enriched with 0.1-100 ppm cadmium and mercury and …

Kentucky Law Survey: Torts, Richard C. Ausness

Law Faculty Scholarly Articles

This issue of the Survey of Kentucky tort law includes recent decisions on false imprisonment, intentional infliction of emotional distress, and products liability. The first case, Consolidated Sales Co. v. Malone, held that Kentucky's shoplifter detention statute authorized a personal search of suspected shoplifters by store personnel. In the second case, Eigelbach v. Watts, the Kentucky Supreme Court adhered to its longstanding rule that physical impact was essential to an action for intentional infliction of emotional distress. Finally, in the third decision, McMichael v. American Red Cross, the Court, utilizing the Restatement's “unavoidably unsafe” rationale, refused to impose …

A Possible Explanation Of Concrete Pop-Outs, James H. Havens, Robert C. Deen

Kentucky Transportation Center Research Report

This report summarizes several years of research relating to damage to concrete and aggregates undergoing freezing and thawing. Basic principles involving freezing and attendant pressures are considered. Application of these principles to the evaluation of concrete was accomplished in experiments on concrete having low and high air contents.

Freeze-thaw characteristics of saturated aggregates relative to physical properties such as porosity, absorption, and bulk specific gravity were studied by submerging individual particles in pre-chilled mercury. Pressures associated with pop-outs in concrete were monitored and are presented along with accompanying theoretical considerations.

Enteric Virus Survival In Package Plants And The Upgrading Of The Small Treatment Plants Using Ozone, Lois S. Cronholm, James R. Mccammon, Marvin Fleischman, Jerry R. Perrich, Valerie Reisser, William Harris, Ronald R. Vanstockum, Khosrow Jaberizadeh, Michael J. Wahl

KWRRI Research Reports

Post-chlorinated effluent collected with a portable viral concentrator from four treatment plants in Jefferson County, Kentucky, yielded infective viral particles from three plants from spring through late fall. The pH, ,chlorine, turbidity, and coliform levels of these effluents indicated that viral persistence was correlated with inefficient processing which produced effluent environments that inhibited disinfection by chlorine. The disinfection potential of ozone was tested on secondary effluent and finished water seeded with poliovirus and Esaheriahia coli. Low doses of ozone inactivated viruses and bacteria in treated water, but not in effluent. The inactivation of bacteria by ozone does not appear …

Toward Maximum Facilitation Of Intent To Create Enforceable Article Nine Security Interests, Harold R. Weinberg

Law Faculty Scholarly Articles

Article Nine of the Uniform Commercial Code generally facilitates individual autonomy in the creation of consensual security interests by imposing limited form and content requirements on security agreements. Private autonomy is subordinated, however, where the Article's draftsmen believed that certain other policies required a degree of regulation. Through the process of interpreting and applying a number of Code provisions which set forth the requirements for creating security interests, a court can effectuate what it considers to be the appropriate balance between facilitating the parties' intent to create a security interest and insuring that regulatory policies, such as protecting creditors and …

Modification Of Kentucky’S Adequacy-Rating Techniques, Charles V. Zegeer, Rolands L. Rizenbergs

Kentucky Transportation Center Research Report

The purpose of this study was to evaluate Kentucky's adequacy-rating methods and procedures and to recommend improvements. The rating procedures used by planning engineers in the highway districts were found to be reliable and consistent. Kentucky's methods were found to be superior to methods used in most states, but several changes are recommended. Additions include credits for accident analysis for urban and rural sections, traffic control devices for urban areas, and traffic safety features for bridges. Skid resistance evaluation was changed from a subjective rating to a measured value. Points assigned to the various rating elements have been revised, and …
