Work program 2009

In 2009 the hydrogeophysics test field Schillerslage/Engensen close to Hannover was installed. Besides extensive measurements with new and classical geophysical methods, drillings, borehole measurements and laboratory measurement on core samples will be done. Petrophysical models are to be verified and developed. The work explicitly concentrates on the transformation of the geophysical parameters into water content, porosity and hydraulic conducivity. New methods such as MRS and seismoelectrics are tackled and approved methodologically.

In the second project part 2010 the focus will be on the transformation of the primary parameters into hydraulic relevant measures. Extensive Lab measurements serve for understanding the scaling properties. Using a couple of classical investigations such as grain size analysis, hydraulic transmissivity tests on cores and samples, and pumping tests the estimates from geophysical measurements can be calibrated. Special attention is payed to the coupling of the different methods.
