Siphon Tubes For Furrow Irrigation In The Kimberleys, K S. Cole

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

Irrigation soils in the Ord River area have a high clay content and erode easily under the influence of running water.

To overcome the problem of erosion in cuts between the head channels and irrigation furrows polythene siphon tubes have been found the most satisfactory.

In this article K. S. Cole, B.Sc. (Agric), Agricultural Adviser, Kununurra, describes the use of siphon tubes for furrow irrigation in the Kimberleys.

Farm Dams In The Wheatbelt, J E. Watson

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

MANY new farm dams are sunk each year in the wheatbelt and much money is spent on them.

With continued development of new land, and increasing stock carrying capacity of older land under legume pastures, the need for more water supplies will continue for a long time.

Firebreaks Without Erosion : Hints To Prevent Firebreak Erosion, Department Of Agriculture, Western Australia

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

AGRICULTURAL fire risks are now greater than they have been in the past and are steadily increasing with the advance of agriculture in Western Australia.

During the past 20 years the area of cleared arable land and the area under crop have more than doubled.

The area of established pasture is four times as great as it was. Pastures and crops are much more productive —and more liable to carry destructive fires than they were.

Developing A State Water Plan Utah's Water Resources--Problems And Needs--A Challenge, Utah Water Research Laboratory

Reports

Of all the natural resources with which Utah has been endowed none is more vital to the social and economic well-being of the people than it water resource. We cannot manufacture water. We have found no acceptable substitute. Not one more drop of water is available for our use today than was available to the pioneers. Yet water uses and water demands have multiplied over the years. Since we can do little to change nature's water allotment to Utah we must learn how to utilize our existing supplies more judiciously. This means devoting increasingly more attention to problems of water …

A Study Of The Hydraulics Of Drop-Inlet-Type Culvert Models, Ronald D. Hughes

Kentucky Transportation Center Research Report

In certain unique situations, a drop-inlet-type of culvert might be employed to a greater advantage than the standard box- or pipe-type culvert. A drop-inlet consists merely of a vertical drop-section at the upstream end of the culvert. The drop section is connected to the main barrel of the culvert by means of an elbow or merely a rightangle intersection. The entrance to the drop-section must collect and funnel the channel water into the drop section. Thus, intercepting dams and sidewalls may be needed to form the entrance. Figure 1 illustrates, in a general way, some of the options which may …

Third Annual Performance Survey Of Reinforced Concrete Pipe Culverts, Ronald D. Hughes

Kentucky Transportation Center Research Report

In April, 1957, under Circular Memorandum 22-40, the Bureau of Public Roads issued a rational criterion covering beddings of reinforced concrete pipe, construction methods, and simplified methods for determining the allowable heights of fill over pipe having given D-load strengths. The states were urged to adopt the criterion; and, accordingly, the Kentucky Department of Highways issued Amendments No. 15 and 16 (Feb, 28, 1958) to its 1956 edition of Standard Specifications for Road and Bridge Construction and Standard Drawings Nos. 11.22 and 11.23. These amendments and standard drawings were patterned after the criterion of the Bureau of Public Roads but …

Derivation Of A Method To Determine Reactions And Deflection Of A Continous Beam On An Elastic Foundation, Louis Richard Fuka

Masters Theses

“The purpose of this thesis is to develop a method for determining the reactions and deflection curve of continuous beams partially supported by an elastic foundation. The method involves representation of an arbitrary loading and the intermediate redundant reactions as Fourier Series. Redundant intermediate reactions are determined by the solution of an equal number of linear equations. The remaining reactions are determined by the application of statics.

This same method can be used for simply supported beams on an elastic foundation and for continuous beams without an elastic foundation”--Abstract, page ii.

The Effect Of Shear Deformation On The Slope Deflection Coefficients., Rajni C. Amin

Masters Theses

"This study was made to determine the effect of shear deformation on stiffness coefficients and carry over factors that are normally used in the calculation of moments in continuous beam or frames by the slope-deflection and Moment Distribution method.

Using the method of total strain energy, the vertical shear V and angle of rotation Ө caused by unit moment were determined for bending moment only and then determined for shear deformation plus bending moment, then carry over factors and stiffness coefficients were computed for each case. The relative effect of shear deformation is small for small depth ratio d_{b …}

To compare the experimental and analytical data, graphs have been drawn for the experimental and analytical quantities of strains and deflections for all the four load increments and eight different angles of inclination. Results of the investigation indicate that the strains and deflections at inclinations …

Removal Of Alkyl Benzene Sulfonate By Precipitation With Cationic Surfactants., Phillip E. Custer

Masters Theses

"The extensive use of synthetic detergents, particularly the nonbiodegradable alkyl benzene sulfonate (ABS), has created many difficulties in water and wastewater. Although a number of processes have been proposed for the abatement of the synthetic detergent problem, a completely satisfactory solution has yet to be developed.

Following a preliminary investigation, three cationic agents, Bionol R0-50, G-263 and Primafloc C-5 were selected to be studied in detail in order to determine their ability to remove ABS by precipitation. Studies were conducted in deionized water, river water and domestic sewage systems using an initial ABS concentration of 10 mg/1 and cationic dosages …

Electrolytic Corrosion Of Reinforcing Steel In Concrete., Lawrence D. Green

Masters Theses

"Deterioration of bridge decks has increased the interest in the corrosion of steel in concrete. A comprehensive review of literature on the subject of electrolytic corrosion of steel in concrete is presented in this thesis.

Development of theory from the literature leads to the following statements. There are two causes for electrolytic corrosion of steel in concrete, stray currents from direct current power sources and the formation of macro-cells within the structure. The corrosion caused by the macro-cells appears to be the more important of the two. Anodic areas exhibit corrosion of the steel and cracking of the concrete.

Many …

The Effect Of Haunched Members On Vierendeel Trusses, Rashmikant D. Parikh

Masters Theses

"The purpose of this study was to analyze a Vierendeel Truss and determine the effect of haunches on moments. Loads were applied at the interior panel points in sequence. The classic slope-deflection method with coefficients taken from a table of frame constants (8) was used for the analysis.

In this investigation, one effect of haunches was determined to be the distribution of moments more evenly throughout the structure. Also, they insure rigidity of the joints and increase architectural flexibility"--Abstract, page ii.

Behavior Of Clay Under Compaction By Vibratory Rollers., Glenn R. Taylor

Masters Theses

"This thesis presents an analysis of the behavior of a lean clay when compacted by commercial vibratory rollers using the results of field investigations conducted by the U. S. Army Engineer Experiment Station, Vicksburg, Mississippi. Conclusions reached indicate that a lean clay soil will behave substantially the same under compaction by a vibratory roller as it does under other conventional methods of field compaction. The relationship of amplitude to the density and moisture content is also examined in this paper with the conclusion that the variations in amplitude of a vibratory roller is not significant as a measure of the …

Swelling Properties Of Putnam Soil, Oscar M. Palma

Masters Theses

"Volume change of Putnam soil under different moisture contents and the swelling pressure developed by the soil at the same moisture contents were investigated using standard test procedures.

The theory of one dimensional consolidation of Terzaghi was reviewed as well as the literature on swelling and swell pressure.

It was found that swell depends mainly on the initial water content, while swelling pressure depends mainly on the dry density of the soil"--Abstract, page ii.
