Extreme Evapotranspiration By Irrigated Alfalfa: A Consequence Of The 1976 Midwestern Drought, Norman J. Rosenberg, Shashi B. Verma

National Drought Mitigation Center: Faculty Publications

The rate of evapotranspiration by irrigated alfalfa at Mead, NE (41°09'Nj 96°30'W, elevation 354 m) reached record levels in 1976. Evapotranspiration was measured with precision weighing lysimeters in a field 1.9 ha in size. Evapotranspiration ranged during the growing season from 4.75 to 14.22 mm day^-l and exceeded 10 mm day^-I on one-third of the days studied. On each day of study the ratio of latent heat flux density (LE) to the sum of the net radiation and soil heat flux densities (Rn+S) was such that LE/ (Rn+S) > 1, indicating the occurrence of significant …

Final Report Buffalo National River Ecosystems Part Iv, R. E. Babcock, E. E. Dale, R. L. Meyer, D. G. Parker, E. G. Smith, M. D. Springer

Arkansas Water Resources Center Technical Reports

Sampling point locations and analytical procedures remained unchanged from those outlined in previous Buffalo National River Ecosystem reports. The only significant change in analytical procedures was a reversion to the glass fiber filter method for collection and extraction of samples for chlorophyll analysis. This change was neeessitated by a need for filtering a larger volume to obtain enough chlorophyll for an accurate measurement. Samples were collected monthly from April 9 through December 30. No samples were taken in January or February due to the extremely uncertain traveling conditions caused by the frequent snows. Prior research indicates that the December 30 …

An Evaluation Of The Effects Of Dredging Within The Arkansas River Navigation System - Volume I - Introduction, Summary And Conclusions, And Recommendations, Arkansas Water Resources Research Center

Arkansas Water Resources Center Technical Reports

The foundation for the development of the Arkansas River was laid with the authorization of many upstream reservoirs in the comprehensive River and Harbor Act of 1946 signed by President Truman. Subsequent authorizations were forthcoming and work began on many of the bank stabilization facilities in 1950 and on the major structures in 1957. The current McClellan-Kerr Arkansas River Navigation System was substantially completed in 1972. The authorized multiple-purpose plan for the Arkansas River and tributaries provided for the construction of coordinated developments in the interests of navigation, hydroelectric power, flood control, bank stabilization, and related benefits including recreation and …

Samples for water quality analyses and phycological studies were taken from the nine standard sampling locations on the Buffalo River nine times during the period from March 1976 through February 1977. The April-June 1976 samples represent nearly identical conditions throughout the spring period; therefore, emphasis was placed on taxonomic research. As the early January sample was considered sufficient~y reflective of stable winter conditions, the December and February periods were. used for detailed microscopic examination of the rich and diverse diatom flora that was found in the river this year. A total of 273 taxa of diatoms were identified from the …

Landsat Linear Trend Analysis - A Tool For Groundwater Exploration In Northern Arkansas, H. C. Macdonald, Kenneth F. Steele, Elizabeth Gaines

Arkansas Water Resources Center Technical Reports

Intelligent development of groundwater resources is a process that requires a thorough understanding of the availability and movement of groundwater. In northern Arkansas knowledge of the deep aquifers is fairly limited, perhaps because economic factors and uncertain yields have discouraged exploitation. The development of these deeper aquifers to their fullest potential as reliable water sources depends on the delineation of high yield areas, a process that may be facilitated by linear trend analysis as outlined in this study. Satellite and photolineament maps of the 13 counties were prepared by use of LANDSAT images and Agricultural Stabilization and Conservation Service photo …

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 …

Water Supplies On Wheatbelt Farms : A General Picture, I A F Laing

Journal of the Department of Agriculture, Western Australia, Series 4

In good rainfall years, farm dams provide water fo more than 50 per cent of the total stock in the wheatbelt.

Other sources include ground water supplies and the piped Comprehensive Water Scheme.

The March 1970 census included questions on farm water supplies including how farmers coped in the 1969-70 drought.

Farm Dams In The Wheatbelt, I A F Laing

Journal of the Department of Agriculture, Western Australia, Series 4

Of the estimated 76 000 farm dams in the wheatbelt, about 8 per cent either leak or are salt affected. The remaining 70 000 dams are capable of holding water for livestock use and can be regarded as sercicable dams.

A great many of the serviceable dams are unreliable water supplies due to the combined effects of lack of runoff from catchments, shallow depth of storage and small size of storage in relation to expected demand from livestock and evaporation loss.

Design Standards For Farm Surface Water Supplies, J L. Frith

Journal of the Department of Agriculture, Western Australia, Series 4

Design is usually concerned with getting adequate return from limited recources. Farm dams which dry up represent dam failure. Less seriously, so too do dams which, although not drying out, never fill; they waste a recource.

Groundwater In The Wheatbelt, E P. O'Driscoll

Journal of the Department of Agriculture, Western Australia, Series 4

In general six factors affect the occurence of groundwater; rainfall, topography, rock type, rock structurs, vegetation, and local evaporation.

Variation in even one of these can affect the potential yield of a bore or well, the groundwater salinity, and even whether any groundwater occurs at all.

Final Report - Lake Mead Monitoring Program, James E. Deacon

Publications (WR)

The Lake Mead monitoring program has developed a substantial body of information on the physical, chemical and biological limnology of Lake Mead since 1972. This report summarizes pertinent aspects of that data, with emphasis on studies completed in 1975 -76. It is our continuing hope that the data developed by us will be useful to an ever broader group of users of the water resource represented by Lake Mead. We have been privileged to see our data have a significant influence in some very important water resource decisions over the past four years. There is every reason to expect that …

Hydrodynamic Separation Of Solids From Solid-Liquid Mixtures, Harry J. Sterling Jr., Don J. Wood

KWRRI Research Reports

Several schemes for separating solid pollutants from water flowing in a closed conduit were examined. Separation based on the momentum differential between the solids and liquids and the centrifugal movement of a conveying liquid were both examined under turbulent flow conditions. The study indicated these processes to have limited applications, primarily due to the difficulties in withdrawing a significant fraction of separated flow and the deleterious effects of turbulent mixing. However, utilization of the differential momentum of solid particles and water when flowing laminarly through a pipe was found to be a viable separation scheme. Significant experimental separations (greater than …

An Evaluation Of The Effects Of Dredging Within The Arkansas River Navigation System, Volume Iv - The Effects Upon The Benthic Associations, Louise Russert Kraemer

Arkansas Water Resources Center Technical Reports

The huge and increasing volume of dredged materials being moved in and from the bottoms of waterways of the U.S. is probably well known to the reader. Lee and Plumb (1974) distinguish between the 2 forms of dredging: (1) mining the bottom sediments (as in shell dredging), and (2) developing and maintaining navigable waterways. They indicate some 380,000,000 cubic yards are dredged annually in this country; maintenance dredging accounting for about 80,000,000 cy, and new construction for about 300,000,000 cy.* These figures (based on 5 yr. averages) do not include dredging by private companies. Smith (1975) comments: "With federal dredging …

An Evaluation Of The Effects Of Dredging Within The Arkansas River Navigation System, Volume V - The Effects Upon The Fish Population, Thomas M. Buchanan

Arkansas Water Resources Center Technical Reports

The Arkansas River extends for 1,450 miles from the eastern slopes of the Rocky Mountains in Colorado, southeasterly through Kansas, Oklahoma, and Arkansas, where it enters the Mississippi River in Desha County. The 448 mile navigation channel which was constructed on the lower portion of this river includes portions of two of its major tributaries, the Verdigris River in Oklahoma and the lower White River in Arkansas. The Arkansas portion of this navigation system consists of three different segments: (1) the lower White River, from its confluence with the Mississippi River to 10 miles upstream, (2) the Arkansas Post Canal, …

Sealing Farm Dams, I A F Laing, R. G. Pepper

Journal of the Department of Agriculture, Western Australia, Series 4

Research over the past 10 years has shown that it is technically possible to seal many leaking farm dams. In some situations a cheap chemical treatment is effective but in most cases it is cheaper to construct a replacement dam.

This article reviews the situation in western Australia and outlines some of the methods used for sealing dams.

Efficiency Of Sprinkler Irrigation Systems, T C. Calder

Journal of the Department of Agriculture, Western Australia, Series 4

Shallow-rooted vegetable crops growing on sandy soils in hot, often windy summer weather, pose a difficult watering problem for most Western Australian vegetable growers.

Irregularities in wetting patterns are common. Wind effects are seldom taken into account in system design. The increasing popularity of knocker-type sprinklers makes these considerations particularily important.

Salt Encroachment : The 1974 Saltland Survey, C V. Malcolm, R. C. Stoneman

Journal of the Department of Agriculture, Western Australia, Series 4

It has long been recognised that the clearing of land for agriculture in the south western Australia is followed by the development of saline soils and streams.

In 1955 and again in 1962, in conjunction with the annual statistical returns, farmers in Western Australia were asked to supply estimates of salt-affected land on their properties.

In 1974 a further survey was conducted, in co-operation with the Australian Bureau of Statistics, using questions covering only the basic information. As the information is again available on a Shire basis a direct comparison can be made with the 1962 survey except for some …

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.' …
