Some Applications Of Geology To Civil Engineering With Special References To New Mexico And The Southwest, Eldred Ray Harrington May 1952

Some Applications Of Geology To Civil Engineering With Special References To New Mexico And The Southwest, Eldred Ray Harrington

Civil Engineering ETDs

Civil Engineers are usually specialists in some branch of the great field. They often get so deep into the forest that nearby trees effectively obscure the forest as a whole. The same is true of the specialists in the numerous branches of the field of geology. The writer has a certain advantage in this study. Not only has he had approximately equal training in both fields but he has lived almost thirty years as an observer outside the "forest", taking occasional excursions into the thickets of the fields but never staying so long in any one of them that he …


An Attempted Determination Of The Approximate Chemical Composition Of The Livingston Volcanics By The Fused Bead Technique, Robert D. Geach May 1952

An Attempted Determination Of The Approximate Chemical Composition Of The Livingston Volcanics By The Fused Bead Technique, Robert D. Geach

Bachelors Theses and Reports, 1928 - 1970

Many fine-grained igneous rocks, basaltic and felsitic in character, are difficult to classify. In numer­ous cases, it is impossible to classify these types of rocks by quick methods of identification. It was hoped at the beginning of this study that refractive indices of glasses formed by quick artificial fusion of samples from selected suites of igneous rocks would show a close cor­relation in chemical composition.


Dispersing Agents In The Pipette Method Of Soil Analysis, Eugene W. Price May 1952

Dispersing Agents In The Pipette Method Of Soil Analysis, Eugene W. Price

Bachelors Theses and Reports, 1928 - 1970

For many years the study of sediments has been a major problem in the field of geology. Especially is this true of the branch of sedimentology known as grain-size distribution. Throughout the years many classical experiments have been performed and procedures evolved from them, all with the purpose of a better and easier determination of the grain-size distri­bution of fine sediments, particularly the clays.


Proposed Special Specification For Reflectorizing Glass Spheres, James H. Havens May 1952

Proposed Special Specification For Reflectorizing Glass Spheres, James H. Havens

Kentucky Transportation Center Research Report

In response to your request for a specification that will apply to glass beads for reflectorizing surfaces of signs, paints, and other night driving aids, we recommend the attached material which is drawn up in the form of a proposed specification. In general, the procedures. and ranges of performance characteristics conform with things that have been discussed by the A.S.T.M. Subcommittee on Traffic Paints. Actually, A.S.T.M. has not adopted a specification, but probably they will have one within the next year or two.

You will note the refractive index and size distribution or gradation are referred to in the specification, …

Field Trip To Daviess And Henderson Counties For Inspection Of Gravel-Bituminous Roads, Ellis G. Williams

Kentucky Transportation Center Research Report

This series of inspections started April 28, with inspection of pavements containing gravel located in Daviess County. It was found that most pavements containing this aggregate has been resurfaced last year using a crushed limestone aggregate. There were, however, three hot-mix and one road-mix pavements remaining.


The Discharge Coefficient In The Coordinate Method For Measuring Pipe Flow, Day L. Bassett May 1952

The Discharge Coefficient In The Coordinate Method For Measuring Pipe Flow, Day L. Bassett

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Agriculture, industry, and community life continue to impose great demands upon available sources of water, particularly in arid and semi-arid regions. Efficient utilization of water, demanding careful distribution and use, implies flow measurement.

The coordinate method for measuring pipe flow finds some application in industry where estimates must be made of the flow of fluids containing relatively large amounts of suspended solids that would render other measuring devices ineffective. Widest application may be found, however, in agriculture where a simple, quick, and inexpensive means for estimating well flow, pump discharge, drain efflux, etc., is necessary if the farmers are to …

A Study Of Runoff From Small Drainage Areas And The Openings In Attendant Drainage Structures, Eugene M. West, J. O. Cornell Apr 1952

A Study Of Runoff From Small Drainage Areas And The Openings In Attendant Drainage Structures, Eugene M. West, J. O. Cornell

Kentucky Transportation Center Research Report

In 1926, John T. Lynch read to the Kentucky Academy of Sciences a paper entitled, "The Relation Between Drainage Area and Waterway Required for Culverts and Small Bridges in Kentucky." The paper was based on a study of many small drainage structures then existing in the highway system, and a general evaluation of the performance of the structures in relation to rainfall and runoff from contributing watersheds.

As a result of this report, and in accordance with the suggestions contained in it, the Department of Highways adopted a system of runoff coefficients applicable to different sections of the state and …


A Test Road For The Evaluation Of Sandstone As An Aggregate In Plant-Mix Bituminous Pavements, Ellis G. Williams Apr 1952

A Test Road For The Evaluation Of Sandstone As An Aggregate In Plant-Mix Bituminous Pavements, Ellis G. Williams

Kentucky Transportation Center Research Report

In eastern Kentucky, deep deposits of sandstones and shales overlie the vast deposits of limestones that prevail throughout the central part of the state. Whereas locally available limestones of high quality comprise the major sources of crushed stone or aggregate for highway paving in the central part of the state, some areas of eastern Kentucky are so far removed from sources of these and other high-type aggregates that transportation of materials becomes a major cost item. It is a matter of record that these costs frequently approach or even exceed the cost of the material at the source, Since aggregate …


An Early Tertiary Stream Channel Between Fish And Pipestone Creeks, Ten Miles West Of Whitehall, Montana, Henry D. Olson Mar 1952

An Early Tertiary Stream Channel Between Fish And Pipestone Creeks, Ten Miles West Of Whitehall, Montana, Henry D. Olson

Bachelors Theses and Reports, 1928 - 1970

Driving between Butte, and Whitehall, Montana, on highway U.S. 10S, one observes an interesting phenomenon in the lower end of Little Pipestone Creek canyon. One side and the bottom of the canyon is cut inthe hard igneous rocks of the Boulder Batholith, and the other side of the canyon is made of unconsoli­dated sand, gravel, and cobbles.


Methods Of Routing Floods Through Reservoirs, Rowland W. Fife Feb 1952

Methods Of Routing Floods Through Reservoirs, Rowland W. Fife

Civil Engineering ETDs

Flood routing through reservoirs serves several major functions. It makes possible the determination of the effect of a reservoir, whether constructed for flood control purposes alone or for other purposes, on historic or predicated future floods at the reservoir site. The effect at the dam site then provides a basis for calculating the effect downstream. It also aids in obtaining the proper manipulation of gated spillways on multiple purpose reservoirs to provide the most advantageous flood control on the stream and at the same time make the best use of the water for power, irrigation, or other purposes.


A Bank Gravel Base Containing Calcium Chloride [Report No. 1], William B. Drake Feb 1952

A Bank Gravel Base Containing Calcium Chloride [Report No. 1], William B. Drake

Kentucky Transportation Center Research Report

This report is concerned with a bank gravel base construction project, and particularly with that part of the base containing calcium chloride as a stabilizing agent. The project was carried out on a relocation of U.S. 62, between Kuttawa in Lyon County and Kentucky Dam on the Tennessee River. A part of the project, as shown on the general location map in Fig. 1, was in Livingston County between the Cumberland and Tennessee Rivers.


Correlation Of The Model And Prototype Tests Of The Conchas Dam Service Spillway And Stilling Basin, Geary W. Allen Jr. Jan 1952

Correlation Of The Model And Prototype Tests Of The Conchas Dam Service Spillway And Stilling Basin, Geary W. Allen Jr.

Civil Engineering ETDs

Conchas Dam and Reservoir, one of the largest water resources projects in the Southwest, build under the supervision of Corps of Engineers, is located below the confluence of the Conchas River and South Canadian River, near Tucumcari, New Mexico. Although it is the source of water supply for the vast Tucumcari Irrigation Project of the U.S. Bureau of Reclamation, its main purpose is flood control. Conchas Dam exerts a tremendous influence on the economy of the northeastern portion of Texas. To a hydraulic engineer its large size and complex hydraulic features present a most challenging field for study and research


An Investigation As To The Uses Of The Topographic Map And Improvements Desired By The General Public, George O. Boeckman Jan 1952

An Investigation As To The Uses Of The Topographic Map And Improvements Desired By The General Public, George O. Boeckman

Masters Theses

"The demand for topographic maps from hunters, fishermen, vacationers, professional engineers etc, has been increasing with each passing year. In 1940 people bought some 700,000 copies of topographic maps. In 1946 sales had jumped to well over 2,000,000 copies. Civilian use of these maps by veterans has contributed substantially to the tremendous expansion of demand for maps since World War II. In recent years, the quality of topographic maps has been greatly improved by refinements in methods and by the use of aerial photography in map compilation. This advancement, and an ever-increasing demand from engineers, geologists, and many others for …
