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 …

Stochastic Simulation Of Daily Rainfall, David M. Allen, C. T. Haan, Don Linton, Jim Street, David Jordan

KWRRI Research Reports

The design of many water resources projects requires knowledge of possible long-term rainfall patterns. In this project a stochastic model based on a first order Markov chain was developed to simulate daily rainfall at a point. The model is applicable to any point in Kentucky (and other areas with similar rainfall patterns).

The model in its present form is useful in providing rainfall inputs into hydrologic models for designing water supply facilities and other water resources systems. The model uses historical rainfall data to estimate the Markov transitional probabilities. A separate matrix is estimated for each month of the year. …

Characterization Of Water Movement Into And Through Soils During And Immediately After Rainstorms, C. T. Haan

KWRRI Research Reports

The movement of water into and through soils in the unsaturated state is basic to many water resources problems including rainfall-runoff models, ground water recharge, irrigation, drainage, evapotranspiration and the movement of pollutants in soils. This study was conducted in an effort to determine if the flow equation based on Darcy's Law and the continuity equation could be used to describe watershed infiltration and thus be incorporated into hydrologic models.

The results of the study indicate that even on apparently uniform soils there is a great deal of variability in soil water properties. Handling this variability plus the difficulty of …

Instrumentation And Development Of Techniques To Measure And Evaluate Meteorological Parameters Important To Hydrology, Duane G. Chadwick

Reports

Hydro-meteorological instrumentation concepts are discussed. The necessity for an economic and reliable telemetering system is recognized and ways are shown how to achieve this objective. Particular discussion is given on total-precipitation and water-content-of-snow sensing. A method is also presented showing how to make isohyetal plots of telemetered precipitation information on an x-y plotter by use of a resistance paper method in conjunction with an analog computer.

The Effects Of Geographical And Climatic Setting On The Economic Advantages Of Alternative Flood Control Measures, Clyde R. Dempsey, L. Douglas James

KWRRI Research Reports

It has long been realized that tributary urban development and channel improvement greatly affect the flow regime in a given watershed. A previous study used the Stanford Watershed Model to derive relationships expressing how the flood peaks in Sacramento, California, might be expected to vary with changing conditions of urbanization, channelization, and tributary drainage area. In order to observe the effects of climatic setting and geographical location on these relationships, the same type of analysis was applied to a drainage area near Louisville, Kentucky.

If reservoir storage is to be considered in a flood control program, it is necessary to …

Quantitative Analysis Of Stream Flow Rate Extremes, Hugh M. Jeffus

Arkansas Water Resources Center Technical Reports

Stream discharge data for the State of Arkansas is analyzed for representative statistical parameters. The statistical distribution most applicable to stream discharge data in Arkansas is the Pearson type III skew frequency curve. The parameters of the Pearson type III curve for all available records in Arkansas are included as Appendix A. The parameters of the logarithmically normal frequency distribution are included as Appendix B for mean daily discharge, minimum daily discharge and instantaneous minimum daily discharge. The logarithmically normal frequency distribution may be used for the lower discharge rates in lieu of the Pearson type III distribution except where …
