Through these layers surface water is infiltrating leading to the groundwater recharge. During this infiltrating a cleaning of contaminated water can occur due to biological and chemical decomposition of the contaminants or due to sorption processes. The infiltration time is given by the hydraulic conductivity and the thickness of the strata overlying the aquifer. The hydraulic conductivity of a layer is inversely related to the clay content. So the clay content is a crucial petrophysical parameter for the groundwater protection. In this work an attempt is made for the assessment of the clay content of near surface material from geophysical measurements. For practical reasons the electrical conductivity was chosen for the clay content estimation. 4950 https://nbn-resolving.org/urn:nbn:de:gbv:8-diss-4041$xR$3Volltext$534 4961 https://macau.uni-kiel.de/receive/diss_mods_00000404 5051 550 5550 Elektrische Leitfähigkeit 5550 Geoelektrik 5550 Grundwasser 5550 Hydraulik 5550 Sediment 5550 Ton <Geologie> 5550 Tongehalt
