Using vertical Fourier transforms to invert potential-field data to magnetization or density models in the presence of topography
Jeffrey Phillips
2014, Conference Paper, Society of Exploration Geophysicists, 2014 Technical Program Expanded Abstracts
A physical property inversion approach based on the use of 3D (or 2D) Fourier transforms to calculate the potential-field within a 3D (or 2D) volume from a known physical property distribution within the volume is described. Topographic surfaces and observations at arbitrary locations are easily accommodated. The limitations of the...
Optimally managing water resources in large river basins for an uncertain future
Edwin A. Roehl Jr., Paul Conrads
2014, Conference Paper, Proceedings of the 2014 South Carolina Water Resources Conference
Managers of large river basins face conflicting needs for water resources such as wildlife habitat, water supply, wastewater assimilative capacity, flood control, hydroelectricity, and recreation. The Savannah River Basin for example, has experienced three major droughts since 2000 that resulted in record low water levels in its reservoirs, impacting local...

Dual-domain mass-transfer parameters from electrical hysteresis: Theory and analytical approach applied to laboratory, synthetic streambed, and groundwater experiments
Martin A. Briggs, Frederick D. Day-Lewis, John B. Ong, Judson W. Harvey, John W. Lane Jr.
2014, Water Resources Research (50) 8281-8299
Models of dual‐domain mass transfer (DDMT) are used to explain anomalous aquifer transport behavior such as the slow release of contamination and solute tracer tailing. Traditional tracer experiments to characterize DDMT are performed at the flow path scale (meters), which inherently incorporates heterogeneous exchange processes; hence, estimated “effective” parameters are...

A multi-scale assessment of animal aggregation patterns to understand increasing pathogen seroprevalence
Angela K. Brennan, Paul C. Cross, Megan D. Higgs, W. Henry Edwards, Brandon M. Scurlock, Scott Creel
2014, Ecosphere (5)
Understanding how animal density is related to pathogen transmission is important to develop effective disease control strategies, but requires measuring density at a scale relevant to transmission. However, this is not straightforward or well-studied among large mammals with group sizes that range several orders of magnitude or aggregation patterns that...
