Conteúdo: | Previous work of Petrovic, Siebert and Rieke demonstrated the possibility of using X-ray transmission computed tomography (CT) scanning for soil blk densitry analysis in soil. We show in the present work that CT can also be used for the measurement of water content in soil. In our case we also show that CT can be applied to measure and follow dynamically the motion for water in soil in 3-dimensions. Further, more inhomogeneities of water content and motion in soil can be observed  with this technique. Using a third generation CT scanner several different techniques can be linear dependence was demostrated for the Hounsfield Units (HU) used in CT and water content. The use of CT for water content and motion in soil in 3-dimensions opens new possibilities in this area of investigations.
