Abstract
Porosity, internal surface area, pore filling, grain size, and temperature have great influence on the velocity of propagation of electromagnetic waves in granular soil. Therefore we investigated these parameters in laboratory to estimate their relevante for field measurement with Ground Penetrating Radar (GPR). Furthermore we verified the applicability of a whole range of mixing formulae which are important for the computation of water content from the propagation vetocity of radar waves.
