Quaternary Geomorphic Features Of The Bear River Range, North-Central Utah, Jerome Vernon Degraff
Quaternary Geomorphic Features Of The Bear River Range, North-Central Utah, Jerome Vernon Degraff
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
The Bear River Range, in north-central Utah, contains a variety of geomorphic elements influenced by the geologic setting and events. Controlling factors of the geologic setting include: (1) a syncline (west) and an anticline with a crestal graben (east) within the part of the mountain range studied, and an adjacent graben valley along the west side of the range; and (2) bedrock of Precambrian and Paleozoic age in the core of the range, predominantly of shallow-marine carbonates and covered in the graben by shaly and conglomeratic rocks of early Cenozoic age, with fanglomerates and lake deposits of later Cenozoic age. …

Some Aspects Of The Salinity Of Mancos Shale And Mancos Derived Soils, James C. Whitmore
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Initial studies to determine the thermodynamic solubility product (Ksp) of gypsum and CaCO3 were conducted. The influence of different electrolyte salts at different concentrations upon the solubility of gypsum and CaCO3 was then tested. Analytical data was utilized in conjunction with a computer to calculate the activity of CaCO3 and gypsum, the ion pair concentration and the solubility product. Indifferent salts increased the solubility of gypsum and CaCO3, and salts with a common ion decreased the solubility of gypsum and CaCO3.
Lithium was found to be the dominant monovalent cation present …
Nitrogen Fertilization Studies In Dryland Winter Wheat And Potential Nitrogen Losses From The Soil At The Blue Creek Experimental Station In Northern Utah, Subhawat Intalap
Nitrogen Fertilization Studies In Dryland Winter Wheat And Potential Nitrogen Losses From The Soil At The Blue Creek Experimental Station In Northern Utah, Subhawat Intalap
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
This study compared the effects of nitrogen sources on the available inorganic soil nitrogen, nitrogen movement, nitrogen losses, and wheat yields when nitrogen fertilizers were applied to soil planted to dryland winter wheat at the Blue Creek Experimental Station in northern Utah.
In the fall 1973 soil samplings, the fertilizers producing the largest mineral nitrogen contents in the 0-30 cm soil depths were ammonium nitrate >ammonium sulfate > S-coated urea, when they were broadcast at the practical rate of 56 kg N/ha. There was no increase in the mineral nitrogen at the dee per depths in the fall or at any …
The Accuracy Of Soil Mapping Units Of Certain Pachic And Cumulic Soils In Northern Utah, Behjat Badamchian
The Accuracy Of Soil Mapping Units Of Certain Pachic And Cumulic Soils In Northern Utah, Behjat Badamchian
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
The purpose of this study was to determine the accuracy of mapping of pachic and cumulic soils in Cache County. The soil maps that were used for this study as the basemap were the Atlas sheets of the published soil survey of Cache County.
Five map units from Mendou, Nebeker, Avon, Hendricks and Winn which include almost 52 percent of the pachic and cumulic soils in the survey area were selected for this study. These five soils cover large areas when compared to other soil series and they are distributed throughout the county. All these map units were recognized as …
Albedo Of The Earth's Surface -- A Comparison Of Measurements Taken On The Ground And From Flying Platforms, Frank D. Eaton
Albedo Of The Earth's Surface -- A Comparison Of Measurements Taken On The Ground And From Flying Platforms, Frank D. Eaton
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
The main objectives of this study were to develop the intricacies of reflected solar radiation from different natural surfaces and to show comparisons between values sensed in space of emergent radiation to ground values obtained from accounting for anisotropic reflection and estimating the effect of the intervening atmosphere. Thus, this study demonstrated that a prior knowledge of the angular distribution of reflected radiation allows determining the true hemispherical reflected radiation from a narrow field of view instrument such as found on a flying platform. Measurements for determining the indicatrices were made from a tower-mounted Nimbus MRIR and, in one case, …
A Model For Designing Surface Drainage Systems In Nearly Level Agricultural Lands, Rafael Maria Rojas
A Model For Designing Surface Drainage Systems In Nearly Level Agricultural Lands, Rafael Maria Rojas
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
The increasing demand for reclamation of periodically waterlogged nearly level agricultural lands in humid tropical areas and the hazard of soil deterioration and soil moisture balance disturbances by current land forming methods suggests the need for investigations of new surface drainage design procedures. This report presents a rainfall-runoff model for simulating hydrographs from ungaged agricultural plots. The model is based on routing procedures and utilizes common soil and hydrologic data. Tests made with several small agricultural water-sheds indicate that the model could be a useful tool in simulating surface drainage design.
Input data for the model consists of (a) rainfall …
Irrigation Scheduling Program For Sugarcane, Terence L. Pearse
Irrigation Scheduling Program For Sugarcane, Terence L. Pearse
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
An estimate of potential evapotranspiration is acquired to implement an irrigation scheduling program. Four equations, which estimate potential evapotranspiration (evaporation) were evaluated for prediction of Class "A" Pan evaporation. The equations used were Penman's combination equation, the Jensen-Haise temperature and radiation equation, and two of the Christiansen-Hargreaves polynomial regression type equations. Measured and calculated radiation was used together with two values of albedo. Four years of daily climate data from Rhodesia was evaluated by general linear regression methods.
Despite the significant variations between the four annual regression lines of each equation, the use of confidence intervals indicate that the Penman …
Modeling Spring Wheat Production As Influenced By Climate And Irrigation, V. Philip Rasmussen Jr.
Modeling Spring Wheat Production As Influenced By Climate And Irrigation, V. Philip Rasmussen Jr.
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
A model has been developed that predicts spring wheat grain and dry matter yield. Preliminary tests show very favorable results when predicting grain yield in two different climatic regimes, one being a dryland and another being an irrigated area. The strengths of the model lie in its simplicity, relatively available input data, and low computer processing time cost. Weakness of the model stem from the assumptions that allow its simplicity. The basic assumption in the model is that grain and dry matter yield can be related to the ratio of actual to potential transpiration, computed for each of five phenological …

Structural Geology Of Cutler Dam Quadrangle And Northern Part Of Honeyville Quadrangle, Utah, Douglas A. Sprinkel
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
The mapped area is located in the north-central part of Utah. The northern part of the mapped area is located in the Basin and Range province and the southern part of the mapped area is located in the Middle Rocky Mountain province. The north-south and east-west dimensions of the mapped area are 11.1 miles and 5.1 miles, respectively.
Paleozoic rocks are exposed in Bear River Narrows, in Cache Butte Divide, and in the Wellsville Mountains. Paleozoic strata, in Bear River Narrows, dip west. The Ordovician Swan Peak Formation crops out in the eastern part of Bear River Narrows. It is …
Dikes Of The Clear Creek Area, Wasatch Plateau, Utah, William Dennis Thomas
Dikes Of The Clear Creek Area, Wasatch Plateau, Utah, William Dennis Thomas
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
The area, covered by this report, includes about 108 square miles in the northeastern part of the Wasatch Plateau in central Utah. Clear Creek, Utah, is near the center of the area.
Stratigraphy of the area is characterized by 18,000 to 20,000 feet of sedimentary rocks above the Precambrian basement. The oldest exposed stratigraphic unit is the 11ancos Formation of late Cretaceous age; the youngest exposed stratigraphic unit is the North Horn Formation of Cretaceous-Tertiary age. The sedimentary rocks are mainly sandstone, shale, and coal. Sandstone and shale are the most abundant.
Structure of the area is characterized by folds …
