Overcoming Stock Watering Problems In The Kimberleys, B Swan

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

ONE of the ever-present problems of the pastoral areas is that of providing: watering-points in reasonably close proximity to the grazing areas.

All too frequently, the country on the river frontages and that in the vicinity of the water-holes becomes eaten out and although there may be ample feed on other portions of the run, it is too far distant from the available water to be effectively utilised.

Comprehensive Survey Of Sedimentation In Lake Mead, 1948-49, W. O. Smith, C. P. Vetter, G. B. Cummings, U.S. Bureau Of Reclamation

Publications (WR)

Reservoirs are becoming an increasingly prominent feature of the American landscape. Built for flood mitigation and to change a fluctuating river into a dependable source of water for irrigation, power, and other purposes, they are predestined, like natural lakes, to be destroyed sometime following their creation. Sedimentation sooner or later robs most lakes and reservoirs of their capacity to store water. The significance of sedimentation in the life of Lake Mead, the largest artificial reservoir in the world, was realized when the plan for the reservoir was conceived, and an aerial survey of the floor was made in 1935 before …

Irrigation In Western Australia : Report On Government-Controlled Areas : 1958-59, H K. Gibsone

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

IRRIGATION in the south-western portion of Western Australia is mainly confined to the coastal plain west of the Darling Range where the three main irrigation districts of Harvey, Collie and Waroona have been established by the State Government.

The Government-controlled irrigation areas extend southward from Waroona (70 miles from Perth) to Dardanup (120 miles from Perth) and have an average width of about five miles.

Water Resources Development -- An Analysis Of Economic Justification Practices Of The Corps Of Engineers, Kerwood W. Barrand

Masters Theses

"Presented herein is a brief analysis of the economic justification practices of the Corps of Engineers as commonly implemented in proposals concerning water resources projects. Where applicable, recommended methods are compared to similar methods advocated for, and accepted by, private engineering firms in similar situations.

The major problem exists in the lack of a profit motive in programs undertaken with the use of public funds. However, a profit can be said to have been realized in public works programs if the total benefits of the programs to all the people exceed the costs of these programs and, further, if the …

Report Of Engineering Research With Recommendations For Strengthening The Program, Vaughn E. Hansen

Reports

Progress of Engineering Research: The growth initiated with the reorganization of the Engineering Experiment Station in 1957-58 has been stready and consistant through 1958-59. Every sign points to continued expansion through the coming year. This growth is shown in Table 1. The number of active projects this year has increased to nineteen, the funds allocated for Engineering research were $53,861 plus $17,826 to contract research, exclusive of approximately $75,000 in the Agricultural Experiment Station. The number of staff members engaged in research is now twelve. Contract research money has been obtained to finance four projects which were financed previously with …

The Importance Of Hydraulics Of Surface Irrigation, Vaughn E. Hansen

Reports

Summary: Surface irrigation is a complex hydraulic phenomenon. The hydraulic elements involved in surface irrigation are listed and discussed. Relating these hydraulic elements is the key to efficient irrigation, good design, and permanent agriculture.

Measurement Of Irrigation Water, Eldon M. Stock

Reports

Foreword: Although irrigation has been practiced in Utah for more than one hundred years, irrigation water still is being distributed to farmers with little or not thought about its measurement. A farmer would not think of buying or selling other farm commodities, such as hay, grain, beef cattle, or dairy products, without weighing or accurately measuring them, but at the same time he is often content to accept and pay for the irrigation water received with little or no knowledge as to the actual amount received, or whether or not he is receiving the amount he is entitled to. Measurement …

Evaluation Of Sprinkler Irrigation Systems In Northern Utah, Jay M. Bagley, Wayne D. Criddle

Reports

Summary and Conclusions: Sprinkler irrigation will continue to expand in Utah as well as in other irrigated areas of the world. This method of irrigation is suitable to all farm crops grown in the state and to most soils. It is particularly adapted to steep foothill areas where the water supply can be obtained at higher elevation and pumping is not necessary to develop pressure for the sprinkler systems. Also, much of the irrigated land of the state, particularly along the Wasatch front, is owned and operated by "part-time" farmers. Having the water under complete control and the irrigation schedule …

Relative Productive Value Of Land, Karl Harris, Vaughn E. Hansen

Reports

Location, markets, hard surface roads and other transportation facilities, churches, taxes, schools, and utilities are major factors in the monetary value of land, yet these things do not contribute to the land’s productivity. In this bulletin the only factor considered in determining the agricultural value of land is its productive capacity.

The three major factors in the productive value of land are water, climate, and soil.

These three factors are the principal ones in crop production. If any one of them is unfavorable to plant growth, it can inhibit or even prevent plant growth regardless of how favorable the other …

Plan Of Development For Valley Gravity Project, Julius A. Krug, Michael W. Straus, Wesley R. Nelson

Lower Rio Grande Valley Curated Material

"The Valley Gravity Project Plan has been formulated to furnish an adequate and dependable irrigation water supply for fertile and productive area in the Lower Rio Grande Valley, Texas, It would also provide drainage works, which would remove the threat of destruction of the economy of the area due to effects of a high water table and salt accumulations. The project works would permit generation of the maximum practicable amount of electrical energy which otherwise would be required to operate irrigation pumping plants. Other incidental benefits include fish and wildlife conservation, recreation and flood control."

Freestone County, Texas [Water Quality Survey Of Wells And Springs With Test Hole Data, 1936], Samuel F. Turner

United States Geological Survey: Water Reports and Publications

Introduction

The purpose of this survey was to obtain information concerning existing wells and springs and the quantity and quality of water they yield, and to put down test holes where additional information was needed.

This project was part of a statewide Works Progress Administration project known as a "Statewide Inventory of Water Wells," sponsored by the [Texas] State Board of Water Engineers. The Division of Ground Water of the United States Geological Survey cooperated in the technical direction of the project and the Bureau of Industrial Chemistry of the University of Texas furnished laboratory space and equipment and supervised …
