2007 HT-SP-ERT

The main objective of the experimentation is to use a series of hydrologic tests (hydraulic tomography or HT with steady-state, dipole pumping-and-injection tests) in combination with self-potential measurements (SP) and electrical resistivity tomography (ERT) to model the distribution of transmissivity or thickness-averaged hydraulic conductivity in the central area of the BHRS. Broader objectives include: (a) advancing the development of methods and models for high-resolution subsurface characterization and modeling, including joint inversion of hydrologic and geophysical information, and (b) improving understanding of fundamental physical and biogeochemical processes and research issues associated with subsurface science and engineering (e.g., scale, heterogeneity, parameter relationships, …).
