Groundwater In The Wheatbelt, E P. O'Driscoll

Journal of the Department of Agriculture, Western Australia, Series 4

In general six factors affect the occurence of groundwater; rainfall, topography, rock type, rock structurs, vegetation, and local evaporation.

Variation in even one of these can affect the potential yield of a bore or well, the groundwater salinity, and even whether any groundwater occurs at all.

Past Levels And Present State Of Northern Victoria Land Glaciers, Paul Andrew Mayewski

Earth Science Faculty Scholarship

Before 1973, movement of the Ross Ice Shelf had been measured near the Transantarctic Mountains (Swithinbank, 1963), near Ross Island (Stuart and Heine, 1961) and near the ice front and to the south of Roosevelt Island (Dorrer et at., 1969). Robin (1975), assuming steady state, extrapolated these data across the ice shelf by applying volume conservation principles to measured ice thickness profiles of the ice shelf.

Weathering Stages Of A Tholeiitic Basalt (Dolerite), Queen Maud Mountains, Paul Andrew Mayewski

Earth Science Faculty Scholarship

The sparsity of datable material and key horizons throughout most of the Transantarctic Mountains requires that much of the mapping and correlation of glacial deposits, especially moraines, be based primarily on qualitative techniques. One qualitative method is to characterize the degree of weathering of clasts covering these deposits (Behling, 1971; Calkin, 1971; Nichols, 1971; and Mayewski, 1975). Lacking, however, is a detailed understanding of the role and method of weathering. To help solve this problem, soil studies have been made by Claridge and Campbell (1968) in the Shackleton Glacier region and Everett and Behling (1968), Linkletter (1972), Behling (1971), and …

Petrology Of The Rockport Quarry Limestone (Middle Devonian Traverse Group) Alpena, Presque Isle And Montmorency Counties, Michigan, Charles Willard Cookman

Masters Theses

The basal unit of the dominantly carbonate Traverse Group, the Bell Shale, is gradationally overlain by the Rockport Quarry Limestone which has a thickness of approximately 14 m. The Rockport Quarry Limestone is composed of a dark unrestricted marine subtidal organic-mud packstone facies, comprised of an algal-mat-bearing coral packstone subfacies and a shallower water crinoid-bryozoan grainstone subfacies; a shoal forming stromatoporoid biolithite facies; and a lagoonal micrite facies comprised of a subtidal dense subfacies containing gastropods, ostracods, and calcispheres, and an Intertidal to supratidal fenestral subfacies. The local facies tract reconstructed for the Rockport Quarry Limestone is interpreted to be …

Chlorine Distribution In The Idaho Batholith, Laurence Stewart Istas

Dissertations and Theses

Chlorine is thought to play a major role in the mobilization and concentration of base metals in the formation of ore deposits. The regional distribution of chlorine in the Idaho Batholith was studied to see if this could be related to mineralization or metallic provinces. One hundred forty-eight whole-rock samples, mineral separates, and standards were analyzed for chlorine by x-ray fluorescence.

The expected concentration of chlorine in the biotite fraction was not found. The chlorine was not significantly water leachable from the whole rock samples following normal grinding. The Idaho Batholith as a source for mineralizing chlorine was not established. …

Long-Distance Turbidite Correlations In The Horseshoe Abyssal Plain, William H. Hoyt

Geology Theses and Dissertations

Few studies on modern abyssal plain turbidites have attempted to assess the lateral extent of individual units and few have therefore been able to provide any information on the evolution of turbidity deposits across long abyssal plain distances. In the 4755 m-deep Horseshoe Abyssal Plain, ten distinct lithologic units (six of these Iberian Peninsula-derived turbidites) were delineated in nine piston cores on the basis of stratigraphic position, thickness (range of 20 cm to greater than 500 cm), color, sediment type, sedimentary structures, x-ray mineralogy, and the ubiquitous presence of units in all abyssal plain and supplying canyon piston cores. In …

Geophysical Approaches To Coal Exploration, Gerald B. Rupert

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy

The exploration for minerals by geophysical means has been confined largely to the search for hydrocarbons and metallics while applications to coal exploration are somewhat limited. However, the surface reflection seismic technique has been successfully applied not only to delineating coal deposits but also as a tool in mine exploitation. Furthermore, channel waves generated underground have demonstrated potential in detecting the presence of faults in advance of the coal face and Vibroisis* experiments have been conducted whereby abandoned underground workings have been detected by surface seismic arrays. Examples of all of the preceeding are presented and discussed.

The Effects Of Dredging On The Stability Of An Ebb-Tidal Delta, Lynnhaven Inlet, Virginia, Donald Keith Riggenbach

OES Theses and Dissertations

A channel was dredged in 1965 through the ebb-tidal delta of Lynnhaven Inlet, Virginia. The purpose of this study was to determine if this channel has affected the morphological configuration of the delta. It was proposed that the channel caused the dynamically stable delta to become unstable and change its morphology.

Bathymetric comparisons of seven surveys during the last 122 years, including one conducted during this investigation, show that prior to 1962 and the dredging operations, the delta had become dynamically stable. The present survey shows that the delta has changed its shape in response to the interaction of the …

Properties Of Soils In The Solid Set Irrigation Area Of The Sandhills Agricultural Laboratory, David T. Lewis

Historical Research Bulletins of the Nebraska Agricultural Experiment Station

The introduction of irrigated agriculture and the attendant increase in intensity of land use for agricultural purposes in the Sandhills region of Nebraska requires additional data regarding soils in the area. This work investigated landscape relationships and some of the morphological, physical, chemical, and mineralogical properties of the soil in one irrigated valley. The soils in this valley contain greater amounts of silt and clay than do the soils on the nearby dunes. In addition, some of the valley soils contain layers of much higher clay content and corresponding cation exchange and water holding capacity than the dunal soils and …

Biostratigraphy Of The Snowshoe Formation (Jurassic) In The Izee Area, Grant County, Oregon, Paul Lawrence Smith

Dissertations and Theses

Using the standard Jurassic zonal scheme, this work attempts to determine the ages of the four members of the Snowshoe Formation that crop out in the Izee area. As a corollary, regional correlations are possible. The stratigraphic relationship between the Snowshoe Formation, the subjacent Hyde Formation and the superjacent Trowbridge Formation is also investigated.

Over one thousand fossils were collected from five stratigraphic sections and eight localities. The sections were measured using tape and compass techniques and the relative stratigraphic ranges of the fossils calculated using a computer program written specifically for this project. The ammonite fauna, dominated by the …

Statistical Models For Precipitation, Z. Govindarajulu, Peter Purdue, Frank Cioch

KWRRI Research Reports

The available data consists of daily rainfall for the past 24 years (1948-1972) for Lexington, Louisville and Paducah. However, for Ashland, the data is available for the period of 40 years (1932-1972). The problem is to find an appropriate family of distributions indexed by a suitable number of parameters that fits the maximum daily rainfall. Further, there might be seasonal variations. The following seasons were considered: (i) Dry Convective season: August 1-0ctober 30; (ii) Early Convective season: May 1-July 31; (iii) Late Convective season: November 1- April 30. After extracting the yearly maximums for each of these seasons (see Appendix …

Stratigraphy, Structure, And Petrology Of The Snoqualmie Pass Area, Washington, Lawrence A. Chitwood

Dissertations and Theses

The Snoqualmie pass area lies about 50 mi (80 km) east of Seattle, Washington, along the crest of the Cascade Range. Five stratified units, forming a composite section over 22,000 ft (6700 m) thick, are recognized in the area. They were deformed and later intruded by granodiorite and quartz monzonite porphyry of the Snoqualmie batholith (middle Miocene). The oldest unit, the Denny Formation (Permian), 7000 ft (2100 m) thick, consists of interstratified basalt, andesite and dacite volcanic rocks and limestone and chert beds. This formation is unconformably overlain by a thick conformable sequence of early Tertiary strata which are subdivided, …

Final Report - Lake Mead Monitoring Program, James E. Deacon

Publications (WR)

The Lake Mead monitoring program has developed a substantial body of information on the physical, chemical and biological limnology of Lake Mead since 1972. This report summarizes pertinent aspects of that data, with emphasis on studies completed in 1975 -76. It is our continuing hope that the data developed by us will be useful to an ever broader group of users of the water resource represented by Lake Mead. We have been privileged to see our data have a significant influence in some very important water resource decisions over the past four years. There is every reason to expect that …

Stability And Local Effects Of An Offshore Sand Storage Mound, Dam Neck Disposal Site, Virginia Inner Continental Shelf, William Joslyn Saumsiegle

OES Theses and Dissertations

From 1967 to 1974 medium to coarse sand dredged from the Chesapeake Bay was stockpiled approximately three miles offshore of Dam Neck, Virginia in hopes that the sand could be recovered for local beach renourishment projects. The resulting mound was surveyed over a two year period to determine if the sand is being removed by wave and current action and if the creation of a new feature on the ocean bottom changes the wave refraction patterns and perhaps creates local erosion.

Bathymetric profiles across the storage mound show some apparent morphological changes, but a detailed analysis of this data is …

Hydrodynamic Separation Of Solids From Solid-Liquid Mixtures, Harry J. Sterling Jr., Don J. Wood

KWRRI Research Reports

Several schemes for separating solid pollutants from water flowing in a closed conduit were examined. Separation based on the momentum differential between the solids and liquids and the centrifugal movement of a conveying liquid were both examined under turbulent flow conditions. The study indicated these processes to have limited applications, primarily due to the difficulties in withdrawing a significant fraction of separated flow and the deleterious effects of turbulent mixing. However, utilization of the differential momentum of solid particles and water when flowing laminarly through a pipe was found to be a viable separation scheme. Significant experimental separations (greater than …

The Lower Reaches Of Long Creek, Kentucky: A Karst Anomaly In Allen County, Doral Conner

Masters Theses & Specialist Projects

A field study of the lower reaches of the Long Creek drainage area in southeastern Allen County, Kentucky, established the karst character of that area. The area heretofore had been described as a non-karst area. Four swallow holes, which individually or collectively totally pirate Long Creek, were identified. Two major resurgences of the pirated flow were located and described. A detailed study of a portion of the Long Creek drainage area revealed thirty-four springs, all of which were pirated at least once, and no flow from these springs reached Long Creek by surficial routes. The field survey also revealed dolines …
