The vadose zone dictates how water exists and moves in the shallow subsurface. This, in terms of engineering geology, inevitably leads to volume change of ground, changes in the corrosiveness of the subsurface, and seepage problems (such as seasonal perched …

This vadose zone (the area between the ground surface and the underlying water table) contamination spread vertically and horizontally, contaminating groundwater in several locations. For years, these groundwater plumes expanded and exhibited increasing constituent concentrations, indicating that contaminants were continuing to enter the groundwater from the vadose zone.

These processes were found to be controlled by the alluvial sedimentary geology of the vadose zone, which is highly heterogeneous. This heterogeneity should be consid-ered when interpreting soil and deep vadose zone monitoring data and assessing of the leaching potential of agricultural chemicals.

Abstract. Water infiltration and recharge processes in karst systems are complex and difficult to measure with conventional hydrological methods. In particular, temporarily saturated groundwater reservoirs hosted in the vadose zone can play a buffering role in water infiltration. This results from the pronounced porosity and permeability contrasts created by local karstification processes of
