Geophysical Investigations for Evaluating Water Storage Potential on Agricultural Soils

B051 Geophysical investigations for evaluating water storage potential on agricultural soils INTRODUCTION 1 The knowledge of the soil water retention is one basis for developing flood protection concepts. The research objectives of this project are: Investigation of the water retention (storage) potential of agricultural soils examining the hydraulic conductivity and the noninvasive determination of the near-surface water content (down to 3 m). For flood preventation a decrease of the surface drain rate and therefore a decrease of the erosion should be achieved. The known methods in soil physics to determine the water retention potential are timeconsuming and expensive and they
