Overcoming Stock Watering Problems In The Kimberleys, B Swan Jan 1960

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 …

Water Resources Development -- An Analysis Of Economic Justification Practices Of The Corps Of Engineers, Kerwood W. Barrand Jan 1960

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 …


Factors That Influenced Homesteading And Land Abandonment In San Juan County, Utah, Melvin J. Frost Jan 1960

Factors That Influenced Homesteading And Land Abandonment In San Juan County, Utah, Melvin J. Frost

Theses and Dissertations

Homesteading in San Juan County, Utah is for the most part, located on Sage Plain at elevations between 6,000 to 7,200 feet. Sage Plain is an undulating surface deeply dissected with canyons. The soil is relatively shallow and the predominant vegetation is pinyon, juniper, sage brush and blue-stem grass.

The 52 year mean precipitation is 15.47 inches. Since the beginning of weather records there has been a noticeable decrease in the annual precipitation. There is generally sufficient moisture to mature winter wheat. Pinto beans are also grown in the more favorable locations.

Principle factors that have influenced homesteading and land …
