Analysis Of The Sediment Filtering Action Of Grassed Media, Billy J. Barfield, David T. Y. Kao, E. W. Tollner
Analysis Of The Sediment Filtering Action Of Grassed Media, Billy J. Barfield, David T. Y. Kao, E. W. Tollner
KWRRI Research Reports
The movement of sediment in non-submerged flow through a rigid grass media was studied experimentally by simulating the media with cylindrical nails. Models of sediment movement were developed from probablistic reasoning and from the use of existing parameters describing total bed material in open channel flow. In the probability analysis, the percent sediment trapped was found to be a power function of the number of potential fall paths, Nf,a particle could make from the surface to the bed while traveling through the filter media. The percent trapped was also found to be an inverse power function of the …
Tertiary Treatment Of Wastewater Using Oxidation Ponds, Robert A. Lauderdale, John R. Moeller, Raymond D. Hamilton
Tertiary Treatment Of Wastewater Using Oxidation Ponds, Robert A. Lauderdale, John R. Moeller, Raymond D. Hamilton
KWRRI Research Reports
The purpose of the project was to determine the value of using lagoons as a supplemental process for treating the effluent from an activated sludge wastewater treatment plant.
Only tentative conclusions can be suggested since the project was not carried to completion. It appears that lagoons will have only minimal effect on the amounts of total nitrogen and phosphate in the plant effluent, although conversion of a portion of the ammonia to nitrate can be expected. However, the concentration of ammonia was never lower than that required by EPA guidelines. Some reduction of soluble BOD appears to occur, perhaps through …
Rural Residential Water Demand In Kentucky: An Econometric And Simulation Analysis, Orlen C. Grunewald, C. T. Haan, David L. Debertin, D. I. Carey
Rural Residential Water Demand In Kentucky: An Econometric And Simulation Analysis, Orlen C. Grunewald, C. T. Haan, David L. Debertin, D. I. Carey
KWRRI Research Reports
This study proposed that demand management through pricing policies can be used in conjunction with supply management to solve water supply problems in Kentucky. Economic principles were shown to apply to rural residential water use. From the economic model, a hyperbolic demand function was theorized. The mathematical form of this function used quantity of water as a function of price, income, value of residence, evaporation, and persons per residence. This function was estimated using ordinary least squares regression. A log-linear model was found to be a satisfactory representation of the demand function. Price was the only independent variable which was …

Trace Metals And Major Elements In Water-Soluble Rocks Of Northwest Arkansas, George H. Wagner, Kenneth F. Steele, Doy L. Zachry Jr.
Technical Reports
Trace metals in limestone are potential water contaminants because they can enter the ground water when the limestone is dissolved by carbonic acid and other naturally occurring acids. Four local limestones, the St. Joe and Pitkin Formations (Mississippian) and the Brentwood and Kessler Members of the Bloyd Formation (Pennsylvanian) were sampled in a five county area in Northwest Arkansas. Atomic absorption analyses were made for Na, K, Mg, Ca, Zh, Cu, Ba, Fe, Co, Cr, Ni, Mn, Li and Sr on the acid soluble material of the samples. All the limestones are relatively pure CaCO3 with Pitkin the purest, 93.4%. …

Socioeconomic Impacts Of The Second Stage Of The Southern Nevada Water Project And Its Alternatives, William T. White, Bernard Malamud, John E. Nixon
Publications (WR)
This study evaluates the socioeconomic impacts of the Second Stage of the Southern Nevada Water Project of the United States Bureau of Reclamation, comparing that project with the alternatives of importing water from Nevada areas somewhat removed from the Las Vegas Valley and of leaving the water supply of the Valley basically as it is, the no project alternative.
The study follows, with adaptations and extensions, the general methodology for socioeconomic impact studies as developed and still being evolved in successive socioeconomic analyses of Bureau of Reclamation water projects. The methodology recognizes that the complexity of modern society and water …
Evaluation Of A Recreational Lake Rehabilitation Project, Clyde Brashier
Evaluation Of A Recreational Lake Rehabilitation Project, Clyde Brashier
2019: Dr. Clyde Brashier
Lake Herman, a recreational, shallow, warm water prairie lake near Madison, South Dakota drain in extensively cultivated watershed and acts as a siltation basin for a chain of four lakes. The lake is more than half silted in and since 1968 various rehabilitation efforts have been made, including the construction of silt traps and lake dredging.
Continuation of the monitoring of twenty plus chemical levels and biological populations of green algae, blue-green algae and diatoms has revealed two major changes: (1) ortho phosphate and total phosphorus levels (which increased markedly with the beginning of dredging) have decreased since dredging has …

The Law Of Water Allocation In Kentucky, Richard C. Ausness, Bill H. Flynn
The Law Of Water Allocation In Kentucky, Richard C. Ausness, Bill H. Flynn
KWRRI Research Reports
This study discusses navigability concepts, consumptive rights to surface and ground waters, the disposal of diffused surface waters and the administration of Kentucky's statutory water allocation system.
Federal regulatory powers are based on navigability as is state ownership of submerged lands. Kentucky uses the ebb-and-flow test of navigability to determine title to submerged lands but uses a navigability-in-fact test to determine the scope of state regulatory authority. Consumptive uses of water in Kentucky are governed by the riparian landowner to use as much water as he needs as long as his use does not interfere with the legitimate uses of …

Trace Element Composition Of Stream Sediments An Integrating Factor For Water Quality, Kenneth F. Steele, Harold C. Macdonald, George H. Wagner, William S. Bowen
Technical Reports
Bottom sediments, suspended sediments, and water were sampled along 130 miles of the Buffalo River in northern Arkansas. The water and acid extracts of the suspended sediments and the minus 95 mesh fraction of the bottom sediments were analyzed by atomic absorption spectrometry. All samples were analyzed for Na, K, Mg, Ca, Zn, Cd, Cu, Pb, Fe, Co, Cr, Ni, and Mn. Selected bottom samples also were analyzed by As, Hg, and Zr. Zr was determined by x-ray fluorescence. Li and Sr were determined for selected water and suspended sediment samples. There is a general decrease downstream in Fe, Cu, …

Pathogenic Free-Living Amoebae In Arkansas Recreational Waters, Leon W. Bone, David A. Becker
Technical Reports
Selected recreational waters of Arkansas were sampled for pathogenic free-living limax amoebae. Water quality parameters were determined for correlation with amoebic population densities and species diversity. Cultural criteria and animal inoculation revealed no pathogenic strains. The feasibility of introduction and/or induction of pathogenic amoebic strains by environmental factors necessitates further ecological investigaitons.
Survival And Growth Rate Of Channel Catfish As A Function Of Dissolved-Oxygen Concentration, R. W. Raible
Survival And Growth Rate Of Channel Catfish As A Function Of Dissolved-Oxygen Concentration, R. W. Raible
Technical Reports
Channel catfish were raised in water-recirculating systems for several periods of about six months duration each. Initial stock was fingerling size fish (10 to 20 grams). At dissolved-oxygen levels below 2.5 parts per million, mortality was high. Fish raised in tanks held at dissolved-oxygen levels between 3.0 and 6.8 parts per million showed increased gains of weight for each increment of added oxygen. Weight gains were as much as 50 percent higher at 6.8 parts per million compared with weights at 3.0 parts per million. Feed conversion was good in all cases. When feeding was limited to demand, feed conversion …
Water Quality As An Approach To Managing Recreational Use And Development On A Mountain Watershed: South Fork Of The Ogden River-Ogden Valley Area, Bruce A. Johnson, E. Joe Middlebrooks
Water Quality As An Approach To Managing Recreational Use And Development On A Mountain Watershed: South Fork Of The Ogden River-Ogden Valley Area, Bruce A. Johnson, E. Joe Middlebrooks
Reports
The South Fork of the Ogden River, one of several heavily used mountain watersheds along Utah's Wasatch Front, was studied between February 1 and November 1, 1974, to determine the effects of recreation on water quality.
Although the greatest impacts on water quality occurred during spring runoff, it was found that recreational use had a definite effect on water quality. Bacteriological parameters were found to be the most sensitive indicators of contamination.
Differences between heavy weekend and light weekday recreational use were reflected by differences in bacteriological counts. Also, it appears that changes in bacterial water quality were more closely …
Water As A Factor In Energy Resources Development, A. Bruce Bishop, Melvin D. Chambers, William O. Mace, David W. Mills
Water As A Factor In Energy Resources Development, A. Bruce Bishop, Melvin D. Chambers, William O. Mace, David W. Mills
Reports
Water, in many cases, is a key factor in the development of energy resources in the western states. The total water supply available in the arid west is fixed; yet potential water uses in the region are growing continually. In fact, in many areas quantities of water desired to be put to beneficial use has already surpassed the limit of local supplies as indicated by filings for water rights. The availability of water, in adequate quantities and of suitable quality, is one of the essentials to the economic viability of some economic sectors in the states in the Colorado River …
The Effects Of Artificial Destratification On The Water Quality And Microbial Populations Of Hyrum Reservoir, Douglas D. Drury, Donald B. Porcella, Robert A. Gearheart
The Effects Of Artificial Destratification On The Water Quality And Microbial Populations Of Hyrum Reservoir, Douglas D. Drury, Donald B. Porcella, Robert A. Gearheart
Reports
Artificial destratification is being increasingly used in attempts to improve water quality and control eutrophication. Most of the artificial destratification efforts are being conducted by public water supply utilities in efforts to improve reservoir water quality for culinary purposes. At present, artificial destratification is being conducted without a complete understanding of the process or its effects on the reservoir. Whether or not artificial destratification can control algal growth and other microbial processes is a controversial question. The effect of artificial destratification on the microbial flora must be understood if it is to be used effectively as a management tool in …

Biochrome Analysis As A Method For Assessing Phytoplankton Dynamics Phase Ii, Richard L. Meyer
Technical Reports
Selected chemical, physical and biological parameters were determined for a man-made lake, Beaver Lake, on the White River of Arkansas and Missouri. The research program determined the qualitative and quantitative aspects of the temporal and spatial distribution of the algal subcommunities. It was determined that the epipelic, epilithic, epizooic and metaphytic subcommunities had little influence on the euplanktonic subcommunity. The relationship between the qualitative and quantitative analysis of the biochromes chlorophyll-a, -b, and -c and the phytoplankton species clustered into biochrome sets is discussed. The temporal and spatial distributional patterns of temperature, oxygen, ammonia-N, nitrate-N, orthophosphate-P and silicates are described …
Movement Of Pesticides In The Soil Water Fertilizer System, H. Don Scott
Movement Of Pesticides In The Soil Water Fertilizer System, H. Don Scott
Technical Reports
A theoretical and experimental study of the transport of pesticides was conducted in several Arkansas soils with metribuzin, a herbicide. In a field study, chloride and metribuzin were applied to a Captina silt loam under maximum leaching conditions and their redistribution was compared with that of soil water. Metribuzin was found in significantly detectable quantities to a depth of 61 cm; the largest concentrations were detected in the surface 23 cm and particularly in the 0-5 cm increment. Two days after application 72.6 and 33.6% could be detected in the vegetation and no-vegetation plots. The metribuzin half life was 7.88 …

Heat And Moisture Conduction In Unsaturated Soils, J. A. Havens, R. E. Babcock
Technical Reports
Mathematical models are developed for the prediction of heat transfer from hot water pipes buried in the soil. Heat transfer in the absence of moisture transfer is described as a function of the difference between the temperature of the pipe and the temperature of the soil surface. The energy balance is used to determine the longitudinal temperature distribution of the water. The method is extended to describe a system of equally spaced, parallel buried pipes. Soil temperature profiles around the pipes are presented. The model is used to calculate the land area that can be heated by an underground piping …
Evaluation Of Recovery In A Polluted Creek After Installation Of New Sewage Treatment Procedures, Robert A. Kuehne
Evaluation Of Recovery In A Polluted Creek After Installation Of New Sewage Treatment Procedures, Robert A. Kuehne
KWRRI Research Reports
Response of Hickman Creek near Lexington, Kentucky to alleviation from serious sewage pollution was studied from January, 1973 through July, 1974. Wastes are now handled from an efficient secondary treatment facility and four sequential polishing lagoons before chlorination and discharge to West Hickman branch.
Physico-chemical tests gave no strong indication of residual pollution effects at the start of the study, approximately six months after the treatment facility opened. At low flow a slight oxygen sag, probably associated with algal growth in the lagoons, persists downstream from the outfall. Mean values for turbidity, nitrates and COD are somewhat higher at the …
