Paleocene To Miocene Foraminifera From A Well Near Gloucester, Virginia, Nelson Stanley Ford
Paleocene To Miocene Foraminifera From A Well Near Gloucester, Virginia, Nelson Stanley Ford
OES Theses and Dissertations
Lithologic analysis of twenty-one core samples from a well near Gloucester, Virginia, when compared to published descriptions of formations occurring in the study area, indicates the presence of five formations. From oldest to youngest these units are the Aquia (late Paleocene), Nanjemoy (early Eocene), Chickahominy (late Eocene), Old Church (late Oligocene and early Miocene), and Eastover (late Miocene) formations. Comparison of the stratigraphic ranges of key planktic and benthic foraminifera from each of the core samples shows chronological agreement with previously published ages for each of these formations.
Paleoenvironmental analysis of each of the formations in the well is based …
Iceberg Severity Off The Canadian East Coast (An Analysis Of The 1991 Iceberg Season), Jerome Edward Salloum
Iceberg Severity Off The Canadian East Coast (An Analysis Of The 1991 Iceberg Season), Jerome Edward Salloum
Theses and Dissertations (Comprehensive)
The 1991 iceberg season on the Grand Banks was the second most severe on record. Over a 218-day period, a total of 2002 icebergs traversed latitude 48°N. Percentages of sightings involving medium and large icebergs greatly exceeded normal values. Thus, the season was mxtstanding, not only in terms of flux numbers, but in terms of total ice mass delivered. Assuming that this flux anomaly is the product of more efficient advection and less efficient ablation and notzsome sudden surge in upstream berg production, the study investigates various atmospheric and sea surface conditions as contributing factors to a near record iceberg …

This study examines hydrological and geochemical processes in a continuous permafrost setting in the Canadian High Arctic on Axel Heiberg Island (79°25 ' N; 90°45 ' W) with the following objective: to identify spatial and seasonal variation in hydrology and geochemistry of the East Inflow (EIF) and West Inflow (WIF) sub basins draining into Colour Lake and relate them to processes operating in the basins. Field work in the catchment was carried out between 20 May to 16 August 1991 and 23 July to 20 August 1992. Surface flow and suprapermafrost groundwater in the active layer were monitored to assess …
River Channel Stability And The Implications For Fish Habitat, John T. Beebe
River Channel Stability And The Implications For Fish Habitat, John T. Beebe
Theses and Dissertations (Comprehensive)
The purpose of this project was to investigate various aspects of river channel stability as they relate to fish habitat. Two headwater creeks of the Credit River system, Black and Silver Creeks, and their confluent stream, the West Credit River in Southern Ontario were used in the study. Thirty-five cross-sections were established and revisited during four flow regimes, summer base flow, fall secondary peak flow, spring melt-high flow and post-spring high flow. Measurements of width, depth and temperature were taken at these times. Water samples were taken for determination of suspended sediment concentration. Channel stability was investigated in relation to …
Investigation Of Hydrometeorological Relationships, Pasu Glacier Basin, Northern Pakistan, Bob Boyce
Investigation Of Hydrometeorological Relationships, Pasu Glacier Basin, Northern Pakistan, Bob Boyce
Theses and Dissertations (Comprehensive)
Records of air temperature, global radiation and discharge from the Pasu Glacier basin in the Upper Indus River Basin have been examined with a view to developing a modest understanding of the simple physically based processes in action within this globally extreme mountainous region. Some glaciological data are also reported but in a preliminary manner. Relationships between air temperature characteristics, global radiation and discharge were investigated using correlation techniques. Daily average air temperatures recorded at the highest meteorological station, Parundas (4200m), provide the strongest degree of association with discharge. The data shows that this highly glacierised Karakoram basin exhibits similar …
Hydrologic Investigations Of Meltwaters Draining Gornergletscher And Findelengletscher, Switzerland Using Hydrochemistry And Isotopic Analyses, Robert A. Metcalfe
Hydrologic Investigations Of Meltwaters Draining Gornergletscher And Findelengletscher, Switzerland Using Hydrochemistry And Isotopic Analyses, Robert A. Metcalfe
Theses and Dissertations (Comprehensive)
The purpose of this thesis is to investigate the hydrological dynamics of Gornerglestcher and Findelengletscher, Switzerland by performing hydrochemical analyses on the bulk runoff exiting the portal of these two alpine glaciers. The hydrochemical analyses utilized electrical conductivity, as a surrogate for total dissolved solids, to determine the flow of routing of the bulk runoff (englacial or subglacial as defined by Collins, 1979b) and 8^18O to determine the contributions of pre-event and event water to bulk runoff during precipitation events. The pre-event water was defined as a combination of snow meltwater, ice meltwater and groundwater as these flow components could …
The Role Of The Vadose Zone In The Generation Of Runoff From A Headwater Basin In The Canadian Shield, Robert Alex Maclean
The Role Of The Vadose Zone In The Generation Of Runoff From A Headwater Basin In The Canadian Shield, Robert Alex Maclean
Theses and Dissertations (Comprehensive)
Hydrological processes occurring within the vadose zone, especially in heterogeneous soils and tills typical of the Canadian shield, are not well understood. This research investigates the importance of the vadose zone in a small headwater basin (Harp 4-21) in the Canadian shield with respect to the generation of stream runoff quantity and quality during episodic rainfall and snowmelt events. The study focused specifically on: firstly the effect of variable antecedent moisture conditions on water-table and stream response, secondly, the significance of the stored vadose water in water extracted from a rising water-table, and thirdly the significance of preferential flowpathways in …

Determination Of Morphologic And Volumetric Change, Peyto Glacier, Alberta, 1966-1989, Peter J. Glenday
Determination Of Morphologic And Volumetric Change, Peyto Glacier, Alberta, 1966-1989, Peter J. Glenday
Theses and Dissertations (Comprehensive)
During the summer months of July and August 1989, approximately 23 years after a photogrammetric survey on August 22, 1966, Peyto Glacier, a glacier selected for study during the International Hydrologic Decade (IHD) 1965-74, was re-surveyed using terrestrial geodetic surveying techniques. The volumetric and morphologic change of Peyto Glacier, Alberta from 1966 to 1989 is estimated through a combined application of digital cartometry, digital geodetic survey and Triangulated Irregular Network (TIN) digital terrain modeling and analysis. Changes in glacial volume, areal extent, teriminus position, percentage basin glaciation, slope, and aspect for the 23 year interval are shown. Additionally, a 1:10000 …
Hydrogeology And Water Budget Analysis Of Two Interdunal Ponds Nags Head Woods Ecological Preserve, Dare County, North Carolina, Richard A. Hisert
Hydrogeology And Water Budget Analysis Of Two Interdunal Ponds Nags Head Woods Ecological Preserve, Dare County, North Carolina, Richard A. Hisert
OES Theses and Dissertations
Ground-water-fed interdunal ponds in Nags Head Woods Ecological Preserve lose as much as 7600 m3 yr-1 of water through evaporation. This withdrawal of groundwater is sufficient to significantly alter flow patterns through the surficial aquifer on Bodie Island, N.C. Statistical analyses of evaporation estimates derived by various methods indicate a weak correlation, (r2=0.4-0.5) between pan evaporation data from Aurora, N.C. and pond evaporation at Nags Head Woods calculated by water budget analyses.
Results of stratigraphic and pedologic analyses in and around the ponds indicate that the ponds formed after development of multiple generations of dunes. This …

Characteristic Discharge And Suspended-Sediment Relationships In Two Glacier-Fed Rivers In The Karakoram, Richard E.J. Kelly
Characteristic Discharge And Suspended-Sediment Relationships In Two Glacier-Fed Rivers In The Karakoram, Richard E.J. Kelly
Theses and Dissertations (Comprehensive)
The purpose of this thesis is to investigate relationships between meltwater flow and production and flushing of suspended-sediment beneath two alpine glaciers. During the ablation seasons of 1987 and 1988, discrete, hourly measurements were taken of discharge, stage, suspended-sediment concentration and electrical conductivity in two rivers draining catchments of the Bualtar and Batura Glaciers in the Karakoram, N. Pakistan. The discharge time series of the Bualtar River reveals that flow varies over a daily period of three to four weeks, at a diurnal level and over one to four hours. Over all three time scales, electrical conductivity is inversely proportional …
Water Quality Dynamics In Meltwaters Draining Peyto Glacier, Alberta, Christopher Bradley
Water Quality Dynamics In Meltwaters Draining Peyto Glacier, Alberta, Christopher Bradley
Theses and Dissertations (Comprehensive)
Variations in the quantity and quality of meltwaters draining Peyto Glacier, Alberta, are assessed to examine to what extent meltwater characteristics might be indicative of any distinctive source and routing of water through a glacierised drainage basin. Continuous monitoring of solute concentrations of the principle melt-stream, Peyto Creek, was undertaken for significant periods in 1982, 1984 and 1987, coupled with measurements of suspended sediment concentration at the glacier terminus. Discharge of meltwater was determined for periods in 1982 and 1987. Supplementary monitoring of hydrogen-ion variation and total solute concentration was undertaken at additional sites within the basin, at a stream …
An Evaluation Of Phosphorus Export From Four Urban Land Uses During Summer Rainfall-Runoff Events In The Laurel Creek Watershed, E. Martin Pemberton
An Evaluation Of Phosphorus Export From Four Urban Land Uses During Summer Rainfall-Runoff Events In The Laurel Creek Watershed, E. Martin Pemberton
Theses and Dissertations (Comprehensive)
Cultural eutrophication, resulting from anthropogenic inputs of nutrients, such as phosphorus, can be detrimental to aquatic ecosystems. The effectiveness of recent phosphorus abatement programs, focused on point source inputs such as municipal and industrial effluent, has brought attention to the reduction of non-point sources, such as urban runoff. Target phosphate loads for the Great Lakes, set by the International Joint Commission, are deemed unattainable, without phosphorous reduction from non-point sources (Yaksich and Rumer, 1980), and it is with this knowledge that this thesis is undertaken. Analysis of phosphate export data from areas of different urban land uses indicates that residential …
Bed Load Measurements: Nottawasaga River And Selected Tributaries, Ontario, Canada, Marylou B. Burkard
Bed Load Measurements: Nottawasaga River And Selected Tributaries, Ontario, Canada, Marylou B. Burkard
Theses and Dissertations (Comprehensive)
Between July, 1989 and March, 1990, bed load samples were taken from ten bridge sites on the Nottawasaga River and three of its tributaries. The Helley-Smith Sampler was used to collect bed load samples, the DH-48 Suspended Sediment sampler was used to sample the suspended load, and velocity estimates were obtained with a Marsh-McBirney Model 512M electromagnetic current meter. Results show that the Pine River, which is a tributary of the Nottawasaga River, had higher bed load transport rates than the Nottawasaga River. The other tributaries, Willow Creek and Boyne River, transported less. During the summer and fall, bed load …
The Effect Of Mid-Winter Snowmelt Events On Nitrate And Ammonium Concentration In The Unsaturated And Shallow Saturated Zones: A Case Study, Richard J. Elgood
The Effect Of Mid-Winter Snowmelt Events On Nitrate And Ammonium Concentration In The Unsaturated And Shallow Saturated Zones: A Case Study, Richard J. Elgood
Theses and Dissertations (Comprehensive)
During the period of December 19, 1987 to March 28, 1988, the unsaturated and shallow saturated groundwater zones under two agricultural land use sites, near Waterloo, Ontario, were investigated to determine the effect of snowmelt percolation on the groundwater quality. Periods of widely fluctuating temperatures and sporadic rain events produced large changes in snowpack water equivalence. The resulting infiltration of snowmelt significantly altered the extent of the saturated area and the concentration of N (nitrogen) ions in both the soil column and percolate water. An N flux from the vadose (unsaturated) zone to the shallow phreatic (saturated) zone, occurring in …
Depositional And Deformational Structures In Three 'Esker-Like' Ridges, Southwestern Ontario, John D. Parish
Depositional And Deformational Structures In Three 'Esker-Like' Ridges, Southwestern Ontario, John D. Parish
Theses and Dissertations (Comprehensive)
The Dundalk Till Plain in southwestern Ontario is crossed by five “esker-like” ridges, believed to have been formed simultaneously during the early stage of the mid-Port Burce Stadial. The three middle ridges are the focus of this research, with each ridge having a different topographic form, but the length of, and distance between, ridges are similar. Occurrences of differing depositional structures and the presence of deformational structures over short lateral and vertical distances reveal the complexity of processes involved. The dominant primary sedimentary structures are large-scale tabular cross-beds. Many individual cross-beds are composed of poorly sorted, matrix-supported gravels. High variability …

This document is the final technical report on the first phase of a multiyear archeological program conducted in Canyonlands National Park. Some of the purposes of this project are to gather information for upgrading the park's interpretive program, increase the scientific understanding of Canyonlands' prehistory, and prepare a research design to guide future investigations. Archeological inventory of 4500 acres in the Needles District revealed a previously undocumented Archaic occupation and showed that Formative peoples using the area were primarily the Mesa Verde Anasazi, not the Fremont and Anasazi as previously thought. The data also indicate that prehistoric peoples used the …
Human Impacts To Minnesota Wetlands, Carol A. Johnston
Human Impacts To Minnesota Wetlands, Carol A. Johnston
Journal of the Minnesota Academy of Science
ABSTRACT-Minnesota's 3.6 million ha of wetlands have been impacted by a variety of human activities, including agricultural drainage, urbanization, water control, and nonpoint source pollution. More than half of Minnesota's wetlands have been destroyed since the first European settlers arrived, an average loss of about 35,600 ha/yr. Drainage for agriculture is the major cause of wetland loss in Minnesota, particularly in southern Minnesota and the Red River Valley. In addition to impacting wetlands directly, wetland drainage affects downstream areas by increasing flood flows, and releasing sediment and nutrients. Urban development and highway construction affect a smaller proportion of Minnesota's wetlands, …
Some Hydrologic Aspects Of Snowmelt Runoff Under Summer Conditions, In The Barpu Glacier Basin, Central Karakoram, Himalaya, Northern Pakistan, Ali Ghazanfar
Theses and Dissertations (Comprehensive)
Snow and ice in high mountains represent and important water resource in many parts of the world, especially the dry continental interior of Central Asia. In the Northern Areas of Pakistan, mountain ranges are the primary sources of annually renewed water supplies. They give rise to rivers which are the only significant, sustainable source of fresh water. The Indus basin is drained by the river Indus and its major tributaries, the Kabul, Jhelum, Chanab, Ravi and Sutlej. Snowmelt contributes about 70 percent to the annual flow of these rivers, but is not timed to meet the requirements for crop production, …

Environmental Planning Of Large-Scale Water Projects: The Three Gorges Dam Case, China, Long Li
Theses and Dissertations (Comprehensive)
Controversy over the construction of the Three Gorges Dam across the Yangtze River in China is an on-going national issue. Proposals have been advanced by numerous disciplinary research teams to identify the environmental consequences of the project development. However, whether the project will benefit or damage the overall environment still remains in question.
No matter which one of the four storage schemes is going to be put into operation, the human, economic, biological, and physical environmental alterations will have no equal in the our contemporary world and probably even for some time in the future. Above all, flood control, hydro-electricity …

Interbasin Water Transfers: An Appropriate Management Practice For The Great Lakes?, David M. Krentz
Interbasin Water Transfers: An Appropriate Management Practice For The Great Lakes?, David M. Krentz
Theses and Dissertations (Comprehensive)
Regional water deficiencies exist in North America, and proposals have been advanced to ‘correct’ these by transferring water from regions where it is relatively abundant to regions where it is relatively scarce. Many of these proposals identify the Great Lakes as either a potential source of the water, or as a ‘distribution centre’ into which water may be transferred and subsequently removed to regions experiencing deficiencies. Although the Great Lakes contain a very large amount of fresh water, most of it is required in place, and so many not be removed. The Great Lakes Basin is heavily populated and highly …
