In situ characterization methods

Numerous field observations showed a strong evidence that flow in heterogeneous porous and fractured media is organized in channels. Understanding the distribution of fluxes in heterogeneous media is critically needed for our global knowledge of the water cycle, as well as in many engineering fields such as water supply, remediation, geothermal application and oil industry. We are looking for innovative methods in order to accurately estimate hydraulic and physical properties of such heterogeneous structures including: advanced single- and/or cross-borehole hydraulic and tracer tests, novel hydrogeophysical methods, strategies for borehole/borehole interval sealing, innovative sensors and in situ experimental approaches.
