Hydrogeophysical Study at an Olive Farm, S. Italy

B004 HYDROGEOPHYSICAL STUDY AT AN OLIVE FARM S. ITALY Summary 1 We present results of hydrogeophysical experiments at an olive farm with calcareous soils at Canosa S. Italy. Geoelectric subsurface models down to 8 m depth display the main waterfed layer for trees. In infiltration experiments hydroelectrical monitoring images the water penetration into soils in 2D and 3D. From diverse petrophysical (insitu and lab) analyses on soil samples we could establish a reliable empirical resistivity-water content relationship similar to that of Archie. This was applied to derive pore water distributions from electric models. We could find that diverse biological und
