Assessment of Water Retention of Agricultural Soils – Flood Prevention with Geophysics

P050 ASSESSMENT OF WATER RETENTION OF AGRICULTURAL SOILS - FLOOD PREVENTION WITH GEOPHYSICS INTRODUCTION 1 G. KURZ M. MÜLLER and U. YARAMANCI Technical University Berlin Department of Applied Geophysics ACK 2 Ackerstr. 71-76 13355 Berlin Germany The knowledge of the soil water retention is the basis for developing flood protection concepts. The research goals are: Investigation of the water retention (storage) potential of agricultural soils examining the hydraulic conductivity and the non-invasive determination of the near-surface water content (down to 2 m). For flood preventation a decrease of the surface drain rate and therefore a decrease of the erosion should
