Department of Earth and Atmospheric Sciences: Dissertations, Theses, and Student Research
In order to better understand saline groundwater distribution and discharge dynamics within the saline wetlands of eastern Nebraska, electrical resistivity data were collected at three wetland sites within the Little Salt Creek Watershed. Electrical resistivity imaging (ERI) can provide an expanded understanding of saline groundwater distribution through the acquisition of a large number of resistivity measurements collected at the surface; upon inversion, the distribution of resistivity can be displayed in cross-section and subsurface processes serving to control salinity can be inferred. In recent years, several studies have used conventional methods of characterizing groundwater flow within the saline wetlands. These point …
