Water Resources Planning Study For Arkansas And Oklahoma, L. R. Heiple, H. M. Jeffus Jan 1970

Water Resources Planning Study For Arkansas And Oklahoma, L. R. Heiple, H. M. Jeffus

Arkansas Water Resources Center Technical Reports

The purpose of this study is to make an appraisal of the local water resources in the Arkansas River Basin common to the two States of Arkansas and Oklahoma as defined by the Arkansas-Oklahoma Compact Committee (hereinafter referred to as "the Compact Committee"). A review, analysis, and correlation has been made of hydrologic data previously collected by others. Consideration is given to the evaluation at selected sites of the storage and potential use of existing water sources.

Virus Movement In Groundwater Systems, William A. Drewry Sep 1969

Virus Movement In Groundwater Systems, William A. Drewry

Arkansas Water Resources Center Technical Reports

The purpose of this study is to investigate the extent to which soil acts as an agent in the transmission of waterborne viruses. Since many waterborne outbreaks of viral diseases have involved small wellwater supplies contaminated by effluents from subsurface wastewater disposal systems, there is a great need for such information. Results of this study show that virus adsorption by soils is greatly affected by the pH, ionic strength, and soil-water ratio of the soil-water system and various soil properties. Also, it is shown that one cannot predict the relative virus adsorbing ability of a particular soil based on the …

Subsurface Irrigation Research In Arkansas, John P. Hoskyn, Billy B. Bryan Jun 1969

Subsurface Irrigation Research In Arkansas, John P. Hoskyn, Billy B. Bryan

Arkansas Water Resources Center Technical Reports

A pilot study conducted in 1963 indicated that (1) cotton yields could be increased by subirrigation, (2) drilled orifices were unsatisfactory because of internal plugging caused by burrs and drilling particles, and (3) operating pressures of 5 and 10 psi were excessive, and 5 psi probably should be considered as an upper-limit pressure. A greenhouse study of a subirrigation system indicated that 2 psi should, in general, for in-wall orifices, be considered as a lower-limit pressure when orifices are built into the pipe wall. The greenhouse study also indicated that a placement depth of 12 inches was preferable to 18 …

Arkansas Water Resources: Supply, Use, And Research Needs, Jared Sparks Jan 1967

Arkansas Water Resources: Supply, Use, And Research Needs, Jared Sparks

Arkansas Water Resources Center Technical Reports

The purpose of this study is to identify Arkansas’ water resources research needs against an economic backdrop of water supply and use conditions existing in the state. In the aggregate Arkansas has an abundance of high quality water relative to present use. There are local conditions that give rise to water problems, but, in general, critical water problems in Arkansas are emergent and potential rather than actual. The causes of these problems are to be found, in large part, in the economic, legal, and social institutions surrounding water use--and particularly in the economic institutions. Research designed to improve economic efficiency …

Quantitative Analysis Of Stream Flow Rate Extremes, Hugh M. Jeffus Jan 1967

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 …
