Impacts of estimating recharge on groundwater modeling for arid basins.
(2006-05-28)Quantifying recharge and spatially identifying recharge distribution is important for evaluating groundwater sustainability, especially in arid regions. A Guelph Permeameter helped identify specific recharge areas and the ... -
The sequence stratigraphic evolution of the Sturgeon Lake bank, central Alberta, Canada and its regional implications.
(2006-05-29)Sturgeon Lake South (SLS) is an isolated Devonian (Late Frasnian) platform located within the Western Canada Sedimentary Basin (WCSB). Stratigraphic correlation of the Leduc Formation across the WCSB reveals a dominantly ... -
Paleosols as an indicator of ancient landscapes, climates and stratal response during the Triassic: the Salt Anticline Region of Utah.
(2006-05-29)Modern soils are excellent indicators of environmental conditions, and paleosols can be used as proxy for past conditions. This dissertation documents the response of Triassic paleosols and fluvial sediment accumulation ... -
Structural analysis of the Criner Hills, South-Central Oklahoma.
(2006-07-31)It has been suggested that there may have been Quaternary displacement along the Criner Hills Fault in South-Central Oklahoma. The Criner Hills Fault is generally on-trend with the active Meers Fault, which has led some ... -
Fluvial sequence stratigraphy and paleoclimate of the Upper Triassic (Norian-Rhaetian) Chinle Strata, northern New Mexico.
(Tulsa, OK : Society for Sedimentary Geology., 2007-11)Two age-equivalent Upper Triassic (Norian and Rhaetian) fluvial successions in New Mexico were evaluated from a sequence-stratigraphic and paleopedologic perspective. Meter-scale fining-upward fluvial aggradation cycles ... -
Seismo-lineament analysis of the Malibu Beach quadrangle, Southern California.
(2007-12-04)The Santa Monica Mountains are a young, structurally active mountain range within southern California. The purpose of this study was to map seismogenic faults within the Malibu Beach quadrangle. Using available earthquake ... -
Linking onshore and offshore data to find seismogenic faults along the Eastern Malibu coastline.
(2007-12-04)The Santa Monica Mountains form part of the structurally active southern edge of the Transverse Ranges Province. The purpose of this research is to identify and characterize potentially seismogenic faults in onshore and ... -
The county bias of severe thunderstorm warnings and severe thunderstorm weather reports for the Central Texas region.
(2008-06-09)Severe thunderstorm warnings issued by the National Weather Service and severe thunderstorm weather reports dating from January 1, 1986 to December 31, 2005 were analyzed to find a potential county bias in the issuance of ... -
Electrical resistivity imaging for characterizing dynamic hydrologic systems.
(2008-10-01)Electrical resistivity imaging (ERI) is widely used in hydrogeophysical studies for monitoring spatiotemporal variations in hydrologic properties and processes. Its applications to hydrologic settings found in sandy and ... -
Modeling channel erosion in cohesive streams of the Blackland Prairie, Texas at the watershed scale.
(2008-10-02)Stream bank erosion is a product of submerged and subaerial processes. The goal of this research was to assess the application of the submerged jet test to predict erosion of cohesive stream banks in the Blackland Prairie ... -
Geochemical fingerprinting of sediments on the Pear Tree Bottom Reef, near Runaway Bay, Jamaica.
(2009-04-01)Pear Tree Bottom Reef, near Runaway Bay, Jamaica, was originally described by T. F. Goreau in the 1950‟s and is noted for its "Buttress Zone" morphology and presence of sclerosponges at water depths less than 30m. Since ... -
Depositional and diagenetic controls on reservoir quality and their petrophysical predictors within the Upper Cretaceous (Cenomanian) Doe Creek Member of the Kaskapau Formation at Valhalla Field, Northwest Alberta.
(2009-04-03)Valhalla Field, discovered in 1979 and located in northwest Alberta, produces from the Upper Cretaceous Doe Creek Member of the Kaskapau Formation. Original reserves in place are 44 x 106m3 of oil, of which 10.3 x 106m3 ... -
Rise of the Givetian (385 Ma) Forests, Northern Appalachian Basin, Catskill State Park, New York, U.S.A.
(Society for Sedimentary Geology (SEPM), 2010)Forestation on Earth may have profoundly changed fluvial sedimentary patterns, increased the release of bio-limiting nutrients to marine systems and increased the consumption of atmospheric CO₂ through biologic productivity ... -
Abundance and character of organic matter in cretaceous rocks of Central Texas.
(2010-02-02)One of the basic tenants of organic geochemistry states that significant accumulation of organic matter will not occur in well-oxygenated aqueous environments. Changing abundance of sedimentary organic material, therefore, ... -
Methods of determining stream setback corridors in urban watersheds from remotely sensed data in the Dallas metropolitan area, Texas.
(2010-02-02)Bank stability in urbanized streams is worsening in response to increased runoff, causing unprecedented stream erosion. Eroding banks pose a serious threat to existing structures prompting cities to create buffer zone ... -
The Jurassic Norphlet Formation of the deep-water Eastern Gulf of Mexico : a sedimentologic investigation of aeolian facies, their reservoir characteristics, and their depositional history.
(2011-01-05)This study defined the sedimentary facies, reservoir architecture, and depositional history of the Jurassic aeolian Norphlet Formation in the deep-water Eastern Gulf of Mexico. Seven depositional facies were identified ... -
Analysis of calcite-filled faults in carbonate strata, balcones trend near Waco, Texas.
(, 2011-09-14)Five normal faults exposed in the Lehigh Quarry near Waco, Texas, were analyzed. The mechanical stratigraphy of the quarry ranges from relatively strong chalk to marly chalk to chalky marl to relatively weak marl. Higher ... -
A comparison of the Cretaceous (Albian) Edwards Limestone bioherms of Central Texas with the Holocene Coral Reefs of Bermuda.
(, 2011-09-14)The Edwards Limestone of Central Texas is comprised of numerous rudist-dominated patch reefs that are collectively referred to as the Central Texas Reef Trend. These bioherms were protected by the Stuart City barrier reefs ... -
