A Study Of The Street Plan Of Logan, Utah, Paul Walter Gottschalk

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

It is the purpose of this thesis to make a study of the street plan for the City of Logan, Utah, to attempt to analyze its desirable and undesirable features as they affect the community, and to prepare a solution to eliminate, insofar as possible, the undesirable features and preserving the desirable.

Design Of Shallow Wells For Drainage By Pumping, Lewiston Area, Utah, Gregory L. Pearson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

After approximately 25 years of using open drains in the Lewiston Area, Utah, the water table has not changed appreciably from what it was in 1921 when Hart and Adams (4) conducted their drainage investigations. It is still only about three feet below the ground surface. This is not effective drainage, meeting neither of the two primary drainage requirements of an arid or semi-arid agricultural region, namely; preventing an accumulation of excessive water within the depth of soil required for optimum growth of plant root systems, and maintaining the water table at a depth below the ground surface greater than …

The Drainage Problem In The Lewiston Area, Utah, Sterling Davis

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Often where water is artificially applied to land, means must be provided for removal of some of this water. Too much water is just as bad as too little. The increased use of irrigation water in Utah has caused an increased need for drainage. Some irrigated lands are poorly drained. With high water table, yield of crops has been materially decreased, and with present drainage methods only a part of possible production had been attained.

The Drainage Problem In The Draper Area, Utah, Stanley H. Van Orman

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

As a rule, in the practice of irrigation, more water is delivered to a project than is used by the plants, evaporated, or removed by natural drainage. It is now generally accepted that, in the West, irrigation and drainage are necessary complementary practices. With comparatively good irrigation practice the efficiency is about 34 percent; that is, approximately one-third or the water is actually used by the crops. With rather poor irrigation practice the efficiency may drop as low as 12 percent.

A Study Of Land Drainage By Pumping From An Experimental Drainage Well In The Delta Area, Utah, Ellaf Arni Olafson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Although it is now generally accepted that, in the west, irrigation and drainage are necessarily complementary practices, the realization has been slow in developing. Recent estimates indicate that about 8 million acres of land under irrigation in the 17 western states require drainage. For most irrigated lands a depth to groundwater of at least five to ten feet is desirable. Very high capital as well as annual maintenance costs would be involved in meeting this minimum requirement with the usual types of tile and open drains. Indeed, in most instances it cannot economically be accomplished. The purpose of this study …

Engineering In Traffic Safety In Utah, Donald T. Hunter

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Traffic safety involves accident-free movement of physical entities. It includes all means of transportation and is a function of mobility, an important variable affecting directly the mortality rate and increase of accidents. All transportation groups have coincidentally with or without increase of mobility been attempting to reduce accidents. Those notably succeeding are the shipping, railroad, and airline interests. The operating motor vehicle and pedestrian groups have failed conspicuously.

The early means of attaining a better degree of traffic safety in the motor vehicle and pedestrian groups were based on opinions, and though rational, were incomplete because of the dynamic and …

A Critical Analysis Of Methods Of Securing Basic Irrigation Data Used In Water Right Determinations, A. Alvin Bishop

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Agriculture in the Western United States is almost entirely dependent upon irrigation. Irrigation has transformed the desert lands into fertile, producing valleys. It has made possible communities and settlement areas which would otherwise be impossible. Although the achievements of irrigation have been great, there still remains millions of acres of fertile land that will never be reclaimed because there is not available water.

A Method Of Snow Surveying And Its Application To Forecasting Stream Flow, Leslie Bowen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The value of knowing ahead of time the amount of water to be expected from any given stream before the season is to far spent is a valuable asset.

A Study To Determine The Feasibility Of Irrigating The Lands Included In The Cache Valley Water Conservation District No. 1, I. Donald Jerman

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The purpose of this report is to investigate the feasibility of irrigating the lands of the Cache Valley Water Conservation District No. 1. The district, as it now stands, is very much in need of many improvements. The Main canals are now in use and are in a good condition to serve all the lands with the required amount of water, but the few laterals that are now constructed, are in a poor condition, with the remaining laterals yet to be finished.

Before successful irrigation can be practiced, a large portion of the land will require leveling and small areas …

A Study Of The Flow Of Water Over Triangular Weirs And The Determination Of Coefficients Of Discharge For Small Heads, J. Milton Barrett

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The development of artesian and pumped wells as a source of irrigation water has created the need for a measuring device which will be accurate for small discharges. The thin edged weir has been accepted as one of the most accurate and desirable measuring devices for this work. Three types of weirs are now commonly used: the Rectangular, the Cipolleti, and the Triangular Notch weir. Of these types the triangular notch is probably best suited for small discharges (under 3 second feet). The various formulae for discharge over 90% Triangular weirs have been accurately determined for heads over two tenths …

The Movement Of Ground Water And Its Relation To The Drainage Of Irrigated Lands, Ernest O. Larson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

One needs but to review the history of the irrigated projects of the West to see clearly the importance of drainage. Since the passing of the Reclamation Act in 1902, the construction of drainage work by the United States Reclamation Service on seventeen projects located in thirteen western states represents about 12 percent of the expenditures from the Reclamation Fund. The portion for drainage has been spent during the last few years. This work has required an annual expenditure of about $1,000,000 or a total of $8,000,000 to July, 1922⁽¹⁾. The work completed is estimated to have reclaimed …
