The Temperature Dependence Of The Drying Of Horizontal Soil Columns, Craig Loren Wiegand

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A consideration of the physical principles involved in evaporative drying of soil indicates that several physical processes might possibly limit the rate of evaporation. These include the rate of supply of energy to the site of evaporation, the rate of transfer of water vapor through the sample or through the atmosphere above the sample, and the rate of unsaturated flow of water to the soil surface or to the site of evaporation.

Preliminary Report: Monolayer Behavior Studies, 1959, Bureau Of Reclamation

Publications (WR)

During the fall of 1959, monolayer behavior studies were made on two lakes in the southwest; Boulder Basin of Lake Mead, Nevada, and Lake Sahuaro near Phoenix, Arizona. These studies were made to evaluate the effect of geographical and climatological conditions on movement and behavior of monolayers. The Lake Sahuaro tests also were used to provide data for design and development of improved methods of application and maintenance of a film on this lake in anticipation of full scale, evaporation-reduction tests to be performed there during the summer of I960. The Lake Mead studies produced the following general points of …

The Nebraska Sandhill Lakes: Their Characteristics And Fisheries Management Problems, D. B. Mccarraher

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

A brief look at the map of Nebraska will readily point out the obvious fact that the sandhills comprise a considerable portion of the land area of the state. To be more precise, an area encompassing around 20,000 square miles or about one quarter of the total state area. This is indeed a vast prairie region long noted for its fine cattle and native hay crops. It is a region of vegetative dune sandhills, sandy basins and valleys, exposed ground water, spring seep lakes and marshes. Since much is already known concerning the land portion of the sandhills it is …

Black Spot Of Tomatoes, R F. Doepel

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

BLACK SPOT DISEASE IS THE MOST SERIOUS FOLIAGE BLIGHT OF TOMATOES IN THIS STATE. IN SEASONS FAVOURABLE TO ITS DEVELOPMENT SEVERE DEFOLIATION AND FRUIT ROTTING ARE EXPERIENCED.

IN Western Australia, black spot, which is also known as early blight and target spot, is a troublesome disease of long standing. It is caused by the fungus Alternaria solani which also attacks potatoes.

The Development Of Western Australian Sand Plain Soils For Agriculture, Richard Philip Roberts, F. L. Shier

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

IN a recently published economic survey of the Australian wheat growing industry, it was reported that nearly two-thirds of the farms surveyed in Western Australia were located on lateritic "sand plain."

As a random selection was made of the eighty farms that were visited it is reasonable to conclude that a similar proportion of all the State's wheat producing farms are on that type of country.

This constitutes a remarkable change from the earlier days of wheat belt settlement when the sand plain soils were regarded as virtually useless and by-passed for development.

It is the purpose of this article …

Kimberley Research Station : A Progress Report, Department Of Agriculture, Western Australia

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

INTEREST in the agricultural potential of the Kimberley region in Western Australia dates from its early exploration and settlement in the last century.

Several farming development schemes were considered for the area, but were never implemented.

This could be mainly attributable to lack of knowledge of agricultural potentialities, limitations of the local environment and ways of exploiting the local environment.

Up to the present the economy of the region is almost entirely based upon the extensive production of beef and to a lesser extent, wool.

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.

Wild Life In A Modern Age, Clee Francis Howard Jenkins

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

THE present human population of the earth is estimated at about 2 1/2 thousand million, and reliable sources consider that this figure will be doubled by the year 2000.

Although the pessimistic forecasts of Malthus have not yet come true, it is obvious that the world's food requirements, must lead to increased exploitation of land and other primary resources, with consequent repercussions on all forms of wild life.

Facts And Figures For The Man On The Land, J A. Mallett

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

FARM or station life calls for the exercise of so many different skills that the farmer or pastoralist is usually an accomplished handyman.

For those whose schooldays are far behind them however, the most difficult part of many tasks is that of dealing with the calculations involved, and it is hoped that these facts and figures will serve as a handy aid to those whose mathematical ability has not kept pace with their manual and technical skill.

Occurrence Of Mineralized Ground Water In Southern St. Louis And Jefferson Counties, Missouri, Willard Glennon Owens

Masters Theses

"Mineralized ground water occurs at some localities in southeastern St. Louis and northern Jefferson counties, Missouri. This water is usually undesirable and is detrimental to development of ground water resources.

Water well records in the offices of the Missouri Geological Survey and Water Resources provided data for a study of structure, lithology and occurrence of ground water. Water well drillers and property owners were interviewed to obtain additional information concerning drilling problems and quality of water.

Geologic cross-sections, subsurface contour maps and isochlorinity maps aided the study of lithology, structure and areal distribution of mineralized ground water. Relationship is suggested …

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 …

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

During the past year, the project has been in a period of transition from a developmental phase to management and maintenance phases. At this time, most of the major developmental work has been completed, with mainly corrective or finish work remaining. Major developmental work yet to be done includes the laying of buried pipe from the wells to the lake bottom; and the design, construction and installation of suitable hunting blinds for the area. When the aforementioned work is completed the project will settle almost entirely into maintenance and management activities.

Oxygen Permeability Of Free Paint Films, Janice I. Kellerman

Masters Theses

"As early as the mid 1800’s investigations were performed on the gas passage through rubber, but it is only comparatively recently that plastic polymeric materials have come into prominence. One interesting aspect of much experimentation begun was that of permeability, and it was soon evident that, in general, polymeric materials have extremely low permeability of gases. This is, in essence, the basis for use of plastics as packaging materials, balloons, and in many other designs and fabrications where it is desirous and/or necessary to exclude air.

There are several variables which must be taken into consideration in the evaluation of …

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.

Early History Of Malad Valley, Glade F. Howell

Theses and Dissertations

The Malad Valley is geographically located in a unique position in the Pacific Northwest. The Bear River and its main affluent, the Malad River, are the only rivers in the Pacific Northwest that drain into the Great Basin, whereas the other streams and rivers of the states of Washington, Idaho, and Oregon empty eventually into the Pacific Ocean. It is also characterized for being the northern end of prehistoric Lake Bonneville, and eventually it was through this valley that an outlet opened to drain the lake. The soil deposits from this lake left a fertile valley, capable of producing most …
