A Theoretical Study Of Infiltration Into Range And Forest Soils, Joel E. Fletcher, Yehia Z. El-Shafei Jan 1970

A Theoretical Study Of Infiltration Into Range And Forest Soils, Joel E. Fletcher, Yehia Z. El-Shafei

Reports

More than 400 rainfall simulator experiments were examined to detect which soil properties could be used to computer infiltration time relationships. Three theoretical equations were tested to determine their efficacy for calculating infiltration time relationships from soil and site characteristics. It was shown that both the modified Green and Ampt and Fletcher equations could by successfully used. Darcian type equations were developed on laboratory type samples which would show the relations between soil, solution and rainfall properties and infiltration. These latter equations have not been tested on undisturbed soils but give excellent agreement between measured and computed values for time …

Hydrograph Synthesis For Watershed Subzones From Measured Urban Parameters, Joseph B. Evelyn, V. V. Dhruva Narayana, J. Paul Riley, Eugene K. Israelsen Jan 1970

Hydrograph Synthesis For Watershed Subzones From Measured Urban Parameters, Joseph B. Evelyn, V. V. Dhruva Narayana, J. Paul Riley, Eugene K. Israelsen

Reports

An analog computer program was developed to simulate the outflow hydrographs at four locations within the 38th Street Waller Creek urban watershed at Austin, Texas. Actual outflow was gaged at the final outlet of the watershed. This provided a checkpoint for comparing the simulated and observed final outflow hydrographs. The outflow hydrographs for each subzone were obtained by chronologically abstracting interception, infiltration, and depression storage from their precipitation hyetographs. These outflow hydrographs were then routed through Waller Creek channel to obtain the hydrographs at the four desired locations. The advantages of this model are the flexibility in varying the precipitation …

Computer Simulation Of The Hydrologic-Salinity Flow System Within The Upper Colorado River Basin, M. Leon Hyatt, J. Paul Riley, M. Lynn Mckee, Eugene K. Israelsen Jan 1970

Computer Simulation Of The Hydrologic-Salinity Flow System Within The Upper Colorado River Basin, M. Leon Hyatt, J. Paul Riley, M. Lynn Mckee, Eugene K. Israelsen

Reports

Changes in the hydrologic equilibrium of a river basin resulting from resource development also produce changes in the quality pattern. Since the burden of quality maintenance must be shared by users (just as are quantities) predictions are needed for quality changes which might result from contemplated development at any specified location within the river system. This study reports the development of a computer simulation model of the water and salt flow systems within the Upper Colorado River basin. Because of the close relationship between the hydrologic and salinity flow systems, an understanding of the hydrologic system is essential to successful …


Are Pschological Principles Useful?(A Guid To The Study Of Human Learning), David R. Stone Nov 1969

Are Pschological Principles Useful?(A Guid To The Study Of Human Learning), David R. Stone

Faculty Honor Lectures

To some extent, each person is his own doctor, his own economist, his own historian, his own counselor, his own psychologist, and his own teacher.

It is said that a man who is his own lawyer has a fool for a client. Can the same be said of a man's other roles? At least for learning (which professionally intersects education and psychology) any person may have the goal of helping himself to appreciate and evaluate the role of the learning professional.

A knowledge explosion has taken place in the area of learning, as in the many fields of science in …

A Study Of The Growth And Sheath Shapes Of Sphaerotilus Natans In Response To Inhibitors And Specific Reagents, Lo-Ping Chi May 1969

A Study Of The Growth And Sheath Shapes Of Sphaerotilus Natans In Response To Inhibitors And Specific Reagents, Lo-Ping Chi

Biology

The sheath forming bacterium, Sphaerotilus natans is generally considered a nuisance organism. It is a causative agent of bulking sludge as well as the nuisance in commercial fishing areas. A unique characteristic of the bacterium is its coherent sheath. The formation, shape, and growth of the cell and sheath was observed by using seven inhibitors: neomycin, streptomycin, chloramphenicol, penicillin, sodium azide, acridine orange, and phenethyl alcohol. In the study, minimal concentration of inhibitors was used to determine their effect on the cell and its sheath. In many cases, the sheaths developed abnormally, and cells appeared fragmented and isolated as if …

A Method For Plotting Isohyetal Maps Using An Analog Computer, Maurice George Kirwan

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The ability of the analog computer to stimulate physical phenomena is used in conjunction with a resistance paper model of the Walnut Gulch watershed in Arizona to plot constant precipitation maps from data obtained from recorded rainfall. Voltages which are proportional to rainfall at a specific raingage, located at scaled points of the resistance paper model, set up an electric field on the resistive sheet which is detected and processed by the computer. The detected potential is compared to a reference potential, or "precipitation value", and the necessary analog networks allow plotting of the equipotential line which is directly analogous …

Overview


Every child has a right to acquire his own realistic selfevaluation of the career he intends to pursue, and the process of exposure to occupational information should be permitted and encouraged to start at an early age. From this point of view we need to foster concepts and techniques designed to facilitate the vocational maturation of the child. Interaction with counselors, teachers, parents, and community will increase the student's ability to understand the opportunities of the world of work as it relates to his aptitudes and interests and values and to enable him to be more aware of the …


A Study Of Evaporation And Evapotranspiration In Peru, Fernando Chanduvi-Acuña May 1969

A Study Of Evaporation And Evapotranspiration In Peru, Fernando Chanduvi-Acuña

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Twenty-four equations for estimating evaporation and/or evapotranspiration were compared with measured Piche evaporation. At least 1728 months of records from 12 Peruvian stations were analyzed in this study.

Computer programs were developed to work this study and the results were compared by plotting.

It has been found that the equation that best fits the Piche evaporation in the low elevation stations in Peru is Christiansen's formula (ET2) which was used as a base for his formula for Class A pan evaporation (EVC).


A Study Of Precipitation Characteristics For Utah, Tsing-Yuan Chang May 1969

A Study Of Precipitation Characteristics For Utah, Tsing-Yuan Chang

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Data on monthly precipitation for three areas of Southern Utah--Beaver, Cedar City and Ephraim--and three areas of Northern Utah--Salt Lake City, Ogden and Logan--where a series of measuring stations were arranged as traverses from the valleys to the mountain tops; were assembled and analyzed.

The relationships between elevation and precipitation amounts were shown. The Southern Utah stations were drier at the same elevations than the Northern Utah stations and the differences became greater as the elevations increased. There was a close correlation between the high elevation and low elevation stations in the same traverse even with the above divergence.

Ogden's Notorious "Two-Bit Street," 1870-1954, Lyle J. Barnes

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A history which records the weaknesses and failures of society may serve as its conscience. The history of Twenty-fifth Street in Ogden, Utah is that kind of history. It reminds us that it is possible for evil influences to prey upon society to the extent that it weakens and becomes vulnerable to the influence.

First the people became passive. They began to feel that the influence was there and there was little they could do about it. They then began ignoring it as if by doing so it would cease to exist. But it didn't disappear. Instead it grew and …

A Study Of The Exponential Distirbutions And Their Applications, Michael Chang-Yu Wang

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

The exponential distribution is a widely known distribution i n statistical theory. It can be regarded as the continuous analogue of the Poisson distribution, discussed by S. D. Poisson in 1837. The Poisson is a limiting form of the Binomial distribution which can be t race d back as early as 1700, discussed by James Bernoulli. A paper by Marsden and Barratt (1911) on the radioactive disintegration of thorium gives a typical frequency distribution which follows the exponential law (8, p. 89). The exponential distribution has achieved importance recently in connection with the theory of stochastic process and has found …
