...) resistivity sensor. The excellent performance of the new technique, degree of accuracy and the short settling time of less than 30 minutes were confirmed. In this paper, based on in-situ experiments, we investigated the relationship between settling time of the groundwater level in the SWS test hole and N...

... and developed a new measurement technique using the SWS test hole and a foraminate pipe. In this paper, results of in-situ experiments using the new technique are described. THE POSSIBILITY OF LIQUEFACTION ASSUMED BY GEOGRAPHICAL FEATURES In Japan, the possibility of liquefaction of the ground surface...

... and enhanced microbial activity after a few days. Only in the presence of reducing or organically complexing agents critical amounts of toxic heavy metals like Cu, Pb, TI, and CA were mobilized. At present, the laboratory experiments are continued and the necessity for in-situ experiments is discussed...
