Effect Of Lime Quality On Soil Ph Changes, Monroe Rasnake

Soil Science News and Views

Quality of a liming material depends primarily on two factors - purity and size of the individual particles. Purity is an indication of how much active material is present. Particle size determines how fa st the lime can dissolve and react with soil acidity.

Modeling Erosion On Long Steep Slopes With Emphasis On The Rilling Process, Michael C. Hirschi, Billy J. Barfield, Ian D. Moore

KWRRI Research Reports

A model of soil erosion, known as KYERMO, is presented which emphasizes those processes which are important on steep slopes. Particular emphasis is placed on modeling rill development and geometry since this is the least understood process in erosion mechanics. The model requires an input rill pattern.

Rainfall inputs to the model require the use of breakpoint rainfall and kinetic energy. Surface storage is calculated based on random roughness data of Linden (1979). Infiltration is modeled by use of the two layer Green-Ampt-Mein-Larson model as proposed by Moore and Eigel (1981). Runoff is related to rainfall excess and surface storage …

Depositional Environments Of Siliceous Laminites In The Laney Member Of The Green River Formation, Sublette County, Wyoming, Michael G. Rasmussen

Loma Linda University Electronic Theses, Dissertations & Projects

Siliceous shales of the Laney Member of the Green River Formation are exposed in outcrops around Fontenelle Reservoir in the northwest corner of the Green River Basin, Wyoming. An analysis of these shales is important to an understanding of the origin of laminites in the Green River formation. The shales are rhythmic, varve -like laminites, composed of quartz, authigenic potassium feldspar , dolomite, and zeolite minerals. The association of these minerals suggest that the original sediment contained significant amounts of volcanic ash, and were deposited in a shallow, near-shore, oxygenated saline - alkaline lake environment, as inferred from (1) the …

Depositional Environments Of The Miocene Esmeralda Formation, Stewart Basin, Stewart Valley, Nevada, Kevin E. Nick

Loma Linda University Electronic Theses, Dissertations & Projects

The purpose of this study was to determine specific depositional environments of the Miocene Esmeralda Formation in Stewart Basin (Stewart Valley), Mineral County, Nevada. Previous workers have concentrated on paleontological aspects of the basin and have described in detail the molluscs, mammals and macroflora. Less work has been done on the diatoms and spores and none on the fish, algae, wood or ostracodes. Recently, seven lithostratigraphics units of the Esmeralda Formation have been mapped in Stewart Valley (Clausen, 1983).

Detailed lithofacies are described in each of the seven lithostratigraphic units. Lithofacies 1 is composed of porcelanite and diatomite containing plant …

A Comparative Study Of Geologic Information Derived From Visually Interpreted Slar And Landsat Imagery, William Leo Barry

All-Inclusive List of Electronic Theses and Dissertations

Geologists have used numerous tYPes of remote sensors for the interpretation of earth surface features. Two of the more recently developed remote sensors are SLAR (side-looking airborne radar) and LANDSAT (ERTS, Earth's Resources Technology Satellite, renamed L~~DSAT). The author undertook a straightforward qualitative research study to ascertain and compare the amount, types and reliability of the geologic information which can be derived separately from visually interpreted LANDSAT and SLAR imagery. The area selected for this study is located in north-central Arizona. The imagery analyzed consists of unenhanced black and white ... multispectral scanner (MSS) bands 5, 6 and 7 LANDSAT …

A High Resolution Ground Magnetic Study Of Part Of The Albion-Scipio Trend, Steven James Hoin

Masters Theses

A detailed high resolution ground magnetic survey was conducted over part of the Albion-Scipio Oil Field Trend. The purpose of the survey was to delineate any magnetic anomalies associated with the trend. A field method using two magnetometers was employed. Sixteen simultaneous readings were taken at a mobile and a base station, and the field operator read the total field values using a 'T ', or similar pattern. This method eliminated much of the noise associated with ground surveys. The resulting residual magnetic map indicates that the basement rocks consist of mafic and felsic, dikes and plutons. Several discontinuities are …

Design, Construction, And Testing Of A Microprocessor-Controlled Interface Between Analog Geophysical Equipment And A Digital Cassette Recorder, Mohd. Nawawi Mohd. Nordin

Masters Theses

A Digital Data Acquisition System (DDAS) microcomputer was designed and constructed to interface between a six-channel analog seismograph and a digital cassette recorder. The DDAS microcomputer is a relatively inexpensive microcomputer built around the popular Z-80 microprocessor chip. It is portable and has 26K bytes of memory. It was designed to convert analog data in to digital with some processing performed before storing on the digital cassette recorder, for later analysis. The same hardware or circuitry of the DDAS microcomputer can perform other functions and work with other geophysical equipment by changing the software of the microcomputer.

Effect Of Nitrogen Fertilization On Fall Stockpiled Ky 31 Fescue, Kenneth L. Wells

Soil Science News and Views

Much interest has developed during the past several years on improving utilization of tall fescue by accumulating its growth during the fall and delaying grazing until late fall and winter. This technique takes advantages of the buildup of sugars in the herbage which normally takes place as seasonal temperatures cool to near the freezing point. UK forage research has shown that content of sugars in tall fescue herbage can increase from around 8 percent in late summer to around 20 percent after the first few frosts have occurred in late fall. This sugar buildup greatly increases the feed value of …

Modeling Surface And Subsurface Stormflow On Steeply-Sloping Forested Watersheds, Patrick G. Sloan, Ian D. Moore, George B. Coltharp, Joseph D. Eigel

KWRRI Research Reports

A simple conceptual rainfall-runoff model, based on the variable source area concept, was developed for predicting runoff from small, steep-sloped, forested Appalachian watersheds. Tests of the model showed that the predicted and observed daily discharges were in good agreement. The results demonstrate the ability of the model to simulate the "flashy" hydrologic behavior of these watersheds.

Five subsurface flow models were evaluated by application to existing data measured at Coweeta on a reconstructed homogeneous forest soil. The five models were: Nieber 's 2-D and 1-D finite element models (based on Richards' equation), the kinematic wave equation, and two simple storage …

KWRRI Research Reports

Information on fluorescent dyes used for water tracing and the results of six studies are reported. Optical brightener, direct yellow, fluorescein, rhodamine (WT), and other dyes are described and the procedures employed in their use ·in the field and in equilibration experiments are discussed. Three of the six studies consisted of investigations of the equilibration with passive detectors of three of the dyes. The absorption of optical brightener on fabric detectors was apparently linear with concentration and with immersion time, while detectors became rapidly saturated with direct yellow. Equilibrium of fluorescein on charcoal detectors with an elutriating solution was not …

Depositional Model Of The Antelope Coal Field, Wyoming, Christine M. Budai

Dissertations and Theses

The coal-bearing sediments of the Antelope coal field in the southcentral Powder River Basin, Wyoming were deposited in paludal and tributary subsystems of the fluvial system that existed in the basin during the early Tertiary. A depositional model for the Antelope coal field was constructed from data collected from approximately 500 drill holes that penetrated the upper 90 meters (300 feet) of the Fort Union Formation. The depositional environments were interpreted from lithologic descriptions and guidelines established in the literature.

The two main coal seams at the Antelope coal field are the Anderson and stratigraphically lower Canyon coal seams. They …
