Abstract
P049 GEOELECTRICS ESTIMATING CHANGES IN WATER SATURATION OF THE VADOSE ZONE 1 S. MARES L. ZIMA J. DOHNAL Z. JANE AND J.KNEZ Charles University Department of Applied Geophysics Albertov 6 CZ-12843 Prague 2 Czech Republic Summary : Time-lapse multielectrode resistivity survey has been proved as appropriate tool for estimating the seasonal water saturation changes of the vadose zone in relatively homogeneous sandy sediments. Case history is taken from Creataceous of Bohemia. Introduction Vadose zone is a part of the soil or rock medium with pore space saturated only partially by water while the rest of the pore space is occupied
