The Flood Disaster Protection Act Of 1973: A Rational Approach To Flood Damage Prevention, Larry J. Wilson

IUSTITIA

Throughout history, man has utilized rivers for water supply, transportation, power generation, and waste disposal. This strong relationship has encouraged the location of human settlements near rivers and streams despite the risk of periodic flooding. The modern technology of transportation and public services has reduced the necessity for riverside locations, but the development of flood plains in urban areas has continued, resulting in the periodic loss of human life and property when flooding has occurred. Within the United States, flooding has taken over 5000 lives in the last fifty years and causes an estimated $1.25 billion in property damages annually.' …

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%. …

Application Of Satellite Data And Lars' Data Processing Techniques To Mapping Vegetation Of The Dismal Swamp, Jeffrey Allan Messmore

Biological Sciences Theses & Dissertations

This study concerned the feasibility of using digital satellite imagery and automatic data processing (ADP) techniques as a means of mapping swamp forest vegetation. Multispectral scanner data acquired by the Earth Resources Technology Satellite (ERTS-1; renamed LANDSAT-1) was analyzed using ADP techniques developed by Purdue University's Laboratory for Applications of Remote Sensing (LARS). The site for this investigation was the Dismal Swamp, a 210,000 acre swamp forest located south of Suffolk, Va. on the Virginia-North Carolina border. Two basic classification strategies were employed in determining the vegetation mapping capability of ERTS-1 data. The initial classification utilized unsupervised techniques which produced …

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 …

Impact Of Development Of Offshore Oil: East Coast Of South American Case Study, Aldo H. Brussoni

Marine Affairs Theses and Major Papers

To analyze this Coastal Management problem it is convenient to have a regional overview of the entire South Atlantic Coast (South America). Go over some of its physical characteristics, the state of development of the offshore oil industry, the volume of its activities, and other related data, the recreational and the fishing industries, the population and its characteristics. This will develop a regional comprehension which is absolutely necessary to have in mind before analyzing the problems of any particular situation created in a country or an area of a country of the Southwest Atlantic Coast. After covering, very generally, all …

Physical And Chemical Properties Of Outdoor Beef Cattle Feedlot Runoff, C. B. Gilbertson, J. R. Ellis, J. A. Nienaber, T. M. Mccalla, T. J. Klopfenstein

Nebraska Agricultural Experiment Station: Historical Research Bulletins

Within the past decade, emphasis has been placed on the quality of our environment. Beef cattle feedlots have been singled out as a significant source of environmental pollution. Environmental protection provided by control facilities requires basic knowledge of the physical and chemical properties of feedlot runoff. This bulletin summarizes studies of physical and chemical properties of beef cattle feedlot runoff completed from August, 1968 through December, 1972.

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 …

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, …

Pollution Abatement From Cattle Feedlots In Northeastern Colorado And Nebraska, L. K. Porter, F. G. Viets Jr., T. M. Mccalla, L. F. Elliott, F. A. Norstadt, H. R. Duke, N. P. Swanson, L. N. Mielke, G. L. Hutchinson., A. R. Mosier, G. E. Schuman, Lynn R. Shuyler, C. E. Evans

United States Environmental Protection Agency: Publications

Climatic factors, feedlot runoff, and organic material in the runoff were evaluated in experimental and commercial feedlots. The effects of slope, stocking rates, terraces, basins, and holding ponds were evaluated to obtain the best controls for containing runoff. In eastern Nebraska, 70 cm annual precipitation produces 23 cm of runoff; whereas, in northeastern Colorado, 37 cm annual precipitation gives only 5.5 cm of runoff. Large applications of runoff liquid, up to 91 cmon grass-Ladino and 76 cm on corn, in Nebraska did not decrease yields; however, in northeastern Colorado, the concentrated high-salt runoff required dilution before direct application to crops. …

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.

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 …

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 …

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 …

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 …

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 …

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 …

Vegetation Development In Relation To Age Of River Stabilization Structures Along A Channelized Segment Of The Missouri River, John Arthur Vaubel

Nebraska Game and Parks Commission: White Papers, Conference Presentations, and Manuscripts

During the summer of 1974, I sampled sites of vegetation representative of successional trends in plant communities along the Missouri River floodplain from Sioux City, Iowa, to Rulo, Nebraska. Five district community types listed from youngest to oldest are as follows: Salix spp. – dominated, Populus deltoides – dominated, Platanus occidentalis-Ulmus rubra – dominated, Tilia americana-Quercus rubra – dominated, and Quercus macrocarpa-Carya ovata – dominated vegetation.

The technique of relating vegetation succession to age of river stabilization structures was found to be useful and offered a quite precise method of developing a timescale …

The Effect Of Human Activity On The Middle Course Of The Tualatin River, Oregon, Lolita M. Carter

Dissertations and Theses

A diurnal study of biological, chemical, and physical parameters was made on the middle course of the, Tualatin River, which drains a 1840 km² (711 mi²) basin adjacent to metropolitan Portland, Oregon. This portion of the river lies along land in transition of use from rural agriculture to highly urbanized development.

There is no nutrient loading of the river from farming practices because there was no return of water from summer, sprinkler irrigation of commercial crops. However, irrigation significantly reduces the volume of water in the river in the summers.
