Lake Chad Basin (LCB) has experienced drastic changes in land cover and poor water management practices during the last 50 years. The successive droughts in the 1970s and 1980s resulted in a decrease in surface water and ...

-plug porosity data was generated from well-log data with random number generation. The GS model requires basic histograms and variogram models for scaling the computerized tomography (CT) plug data to well log scale as well as integrating the data in a...

In the US, the most commonly used F-T test method is AASHTO T 161 “A.” The equipment for variant A of the test is relatively low cost (~$22, 000) and compact. The relatively low cost stems from the basic construction of a ...

The multiproxy examination of ten soft sediment cores extracted from Triangle Pond was used in order to establish alterations in the northwestern coastal environment of San Salvador Island, The Bahamas over the last 3,500 ...

This study was designed to explain natural seeps of hydrogen gas. Ordinarily H2 occurrences are regarded to be product of the process of serpentinization. However other sources or explanation may exist for the natural ...

contaminants on the hydraulic conductivity of sand. Bulk sand samples from the Missouri River Valley aquifer— a major source of groundwater supply in the U.S. Midwest— were collected for this study. Sand samples, representing the aquifer and vadose zone...

The Smith's Fork (23CL223) archaeological site, located in Clay County, Missouri was investigated using pedestrian survey, ground penetrating radar, shovel testing, archaeological excavations and a geologic study of river terraces. Used in concert...

Thomas Jefferson has long been admired for his influence in many arenas in the colonial era of American history; however, his collection of writings has not been closely scrutinized for his geographic thought. This thesis ...

The Niger River Basin (NRB) has experienced severe droughts and floods under a significant change of the land use and land cover (LULC) with increasing population over the years. The present study is to understand the ...

This study investigates the biogeochemical and inorganic geochemical indicators for past environments and paleohydrology of a high resolution sediment record from the Al-Azraq Basin, Jordan. The second largest basin in ...

Aqaba and Elat are very important port and recreation cities for the Hashemite Kingdom of Jordan and Israel, respectively. The two cities are the most susceptible to damage from a destructive future earthquake because they ...

This dissertation examines the potential of local food as an economic development strategy in the United States. Using an interdisciplinary approach it traces the development of the local food movement within the broader ...

The southern Wadi ‘Arabah Valley in Jordan provides an ideal location to investigate both the paleoseismology and archaeoseismology of the region because it is situated directly along the active Dead Sea transform, and ...

). One part of this work is to investigate TiNbTaZrMo HEAs as a key model compare its properties with 12 bcc HEAs. In this study porosity models were also constructed to reduce the Young modulus for biomedical applications. The second part is to examine...

This dissertation investigates the modulating effects of land-atmosphere and aerosol interactions on meso-scale convective systems across the sub-Saharan West Africa region, and aims at providing a value-added contribution ...

In cold regions, thermal cycles and corrosion of reinforcements are the main factors that cause deterioration in concrete structures. Per each storm event, salt is used to melt snow and ice. Ultimately, water contains ...

A multiproxy analyses of sediment from a 4.3 m core extracted from 25 m water depth on the shelf of the northern Gulf of Aqaba suggest shifts in depositional environments over the past 4000 yrs. Foraminifera assemblages, ...

Calcium silicate hydrates comprise a class of minerals formed synthetically during Portland cement hydration or naturally through various geological processes. The importance of these minerals is immense since they are the ...

Streamside protection ordinances have been established in many urbanizing areas; however, there has been a paucity of assessments of the effectiveness of such ordinances. A quantitative assessment of the ecological ...

The drying of the Lake, located in Central Africa, is one example of a water crisis, which requires more research and studies. The lake has been progressively shrinking since the 1960s due to climate change and anthropogenic ...
