Structural Controls On The Distribution Of Groundwater In Southern Sinai, Egypt: Constraints From Geophysical And Remote Sensing Observations, Lamees Mohamed
Structural Controls On The Distribution Of Groundwater In Southern Sinai, Egypt: Constraints From Geophysical And Remote Sensing Observations, Lamees Mohamed
Dissertations
An integrated (Very Low Frequency [VLF] electromagnetic, magnetic, remote sensing, field, and Geographic Information System [GIS]) study was conducted over the basement complex in Southern Sinai (Feiran watershed) for a better understanding of the structural controls on the groundwater flow. The increase in satellite-based radar backscattering values following a large precipitation event (date: 17, 18 Jan 2010; amount: 34 mm) was used to identify water-bearing features, here interpreted as preferred pathways for surface water infiltration. Findings include: (1) The distribution of the water bearing features (conductive features) correspond to that of fractures, faults, shear zones, dike swarms, and wadi networks; …

Discovering Rock Features With Geophysical Exploration And Archaeological Testing At The Mississippian Pile Mound Site, Upper Cumberland Plateau, Tennessee, Jeremy G. Menzer
Electronic Theses and Dissertations
The Pile Mound survey includes magnetometry paired with targeted ground-penetrating radar (GPR) and electromagnetic induction (EMI) surveys of the mound and testing of associated features over the ca. 6.5 ha site. The GPR survey discovered six rock features (five large rock features within the mound and one marking the outside of the mound). Knowledge of mounds in the Upper Cumberland Plateau (UCP) is lacking—the closest other studied sites are at the Corbin Site, Croley-Evans, Bell Site, and Beasley Mounds, approximately 75 – 100 km away. However, the most similar mound construction is found at Corbin and Cherokee sites, some 175 …

Andrew Fiske Memorial Center for Archaeological Research Publications
The summer of 2015 was the first of three planned years of excavations at the early Christian cemetery at farm Keflavík on Hegranes in the region of Skagafjörður, North Iceland. The excavation is the third phase of Skagfirska kirkjurannsóknin (Skagafjörður Church Project) and is a collective effort of the Skagafjörður Heritage Museum and the Fiske Center of the University of MassachusettsBoston. The collective project goes by the name Skagafjörður Church and Settlement Survey (SCASS). The excavation season started on the 6thof July and finished on the 14thof August. The first two weeks were spent cleaning the surface and removing a …

Glaciological Applications Of Terrestrial Radar Interferometry, Denis Voytenko
USF Tampa Graduate Theses and Dissertations
Terrestrial Radar Interferometry (TRI) is a relatively new ground-based technique that combines the precision and spatial resolution of satellite interferometry with the temporal resolution of GPS. Although TRI has been applied to a variety of fields including bridge and landslide monitoring, it is ideal for studies of the highly-dynamic terminal zones of marine-terminating glaciers, some of which are known to have variable velocities related to calving and/or ocean-forced melting. My TRI instrument is the Gamma Portable Radar Interferometer, which operates at 17.2 GHz (1.74 cm wavelength), has two receiving antennas for DEM (digital elevation model) generation, and images the scenes …
