Carolyn Ruppel

Research Emphasis:

Groundwater Hydrology in the Coastal Zone, Environmental Geophysics for constraining chemical and physical processes in coastal aquifers and salt marshes, links to ecological zonation of salt marshes (salinity, microelevation, permeability, and hydrology controls); theoretical analysis of inductive EM data in high induction number terrains (nonlinear inversion), imaging hydrofacies and lithofacies and groundtruthing with discrete monitoring wells
