Preferential Water Movement in Homogeneous Soils
Summary Preferential water movement is a frequently observed phenomenon in soil science. Especially on natural slopes hydraulic behaviour can sometimes be observed which arises from preferential water flow. If the soil consists of a more or less homogeneous material, the preferential water movement can be caused only by heterogeneously distributed water. A sprinkler irrigation test on a large scale homogeneous dyke model and corresponding measurement results using different techniques have shown on the one hand, that preferential water flow in the form of fingering possibly occurred during the experiment. On the other hand, lateral water movement due to heterogeneously distributed water content inside the dyke body could be observed. Both phenomena were also investigated in simple laboratory experiments. The contribution presents results from the above mentioned experiment which are analysed and discussed.
