Untangling Sea Level and Sediment Supply History of the Panther Tongue Delta, Utah, USA

The Panther Tongue is a fluvio-deltaic parasequence in the lower part of the Star Point Sandstone formation in the Wasatch Plateau, central Utah, deposited during the late Cretaceous period. The sedimentology of the Panther Tongue and adjacent beach ridges parasequence has been extensively described by Hwang & Heller (2002) and Hampson et al. ...

Static Reservoir Model of Crevasse Splays in the Colorado River System, Salar of Uyuni, Bolivia

The Altiplano Basin (Bolivia) exhibits one of the best examples of dryland river systems with a low gradient, where it is possible to obtain field data to build 3D high-resolution geological models of different sediment bodies. This study presents the development and understanding of a 3D geological model for crevasse splays deposited in this...

Control of Fluvial Architecture on the Spatial Distribution of Arsenic Rich Ground Water

In Bihar, India, arsenic rich aquifers are used as a drinking water source by millions of people, even though the arsenic concentration in some places is so high it causes serious health issues. The arsenic concentrations in the aquifers show a large spatial variability, one that is presently unpredictable. The most important factors which play...

Imaging frozen glacio-fluvial bedrock valley infill using Ground Penetrating Radar

A Ground Penetrating Radar (GPR) survey was conducted in April of 2008, collecting 27 km of radar profiles in Sandflugtdalen, a permafrosted glacio-fluvial bedrock valley in West Greenland. Due to low electric permittivity of frozen soil, GPR has good depth penetration of permafrost, up to 80 m using low-frequency (50 MHz) antennae. Resolution...
