Geology of the Wadley South Quadrangle and geochronology of the Dadeville Complex, southernmost Appalachians of east Alabama
(2016-08-01)
Geologic mapping results from rocks in the area of the Wadley South Quadrangle are reported to address basic research questions concerning the Paleozoic tectonometamorphic evolution of the southernmost Appalachians. Key ...
Irrigation and Certificate of Use Compliance in the Wiregrass Region of Alabama
(2017-04-24)
Alabama passed the Water Resources Act of 1993 that included a Certificate of Use (CoU) program for users that have the capacity to withdraw 100,000 gallons per day or more. However, there is concern that some irrigation ...
Ion Probe Dating of Zircons from Wuluke Volcano, NW Tibet, China: Constraints on Magma Evolution
(2016-04-29)
The Ashikule volcanic cluster (AVC) is located in the Ashikule basin, on top of
the Kunlun Mountains in the NW Tibetan Plateau. There is very little research on the
AVC, so further research is necessary in order to gain ...
Geomorphic and Sedimentologic Analysis of Four Streams in Southeastern Alabama: Channel and Habitat Response to Changes in Land Use
(2016-12-09)
Streams of the Southeastern US have varying degrees of degradation due to the long history of agricultural land use, reflected in incising and eroding banks with aggradation of fine grained legacy sediment. These effects ...
Petrofacies and Detrital Geochronology of the Upper Pottsville Conglomerate Magnafacies, Cahaba Synclinorium, Southern Appalachian Fold and Thrust Belt, Alabama
(2016-05-16)
Measures of abundance of extraformational conglomerates and clast composition, taken together, can be used to unravel the unroofing history of an orogenic belt. An attempt has been made in this study to develop a new ...
Saltwater Intrusion and Trace Element Contaminations at the Coastal Aquifers of the Ganges Delta
(2016-12-20)
The coastal area of Bangladesh has a low topography lying at the confluence of the Ganges and Brahmaputra river systems in the Bengal Basin. The distribution of aquifer sediments in the subsurface is very complex where ...
Practical Application of Petrographic Methods to Crushed Stone Aggregate Exploration: Comparing Microstructures and Grain Boundaries to Physical Quality Testing of Aggregate
(2015-12-14)
This research attempts to compare and correlate microscopic properties of aggregate material to the aggregates physical engineering properties. Material was collected and tested to obtain physical and mechanical properties ...
Adaptation and Comparison of Machine Learning Methods for Geomorphological Mapping and Terrace Prediction: A Case Study of the Buffalo River, Arkansas
(2017-05-31)
Working with a high-resolution LiDAR dataset, this research adapts existing techniques from machine learning to the problem of predicting general and specific geomorphic features in the complex terrain of the Buffalo River ...
Flood Risk Assessment for the Vulnerable Populations and Infrastructure: Village Creek, Birmingham, Alabama
(2017-05-15)
Urban flooding is a prominent natural hazard in Village Creek that is associated with the large expanse of impervious surfaces in the area, which enhance storm runoff and overwhelm the drainage capacity of the storm sewer ...
Gravity and magnetic modeling of basement beneath the Appalachian Plateau, Valley and Ridge, and Piedmont provinces, Alabama
(2016-07-18)
Despite the significance of regional geophysical anomalies and the economic potential of the area, central Alabama has lacked detailed crustal gravity and magnetic models. The southeastern United States has undergone at ...
