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

The vadose zone, also termed the unsaturated zone, is the part of Earth between the land surface and the top of the phreatic zone, the position at which the groundwater (the water in the soil's pores) is at atmospheric pressure ("vadose" is from the Latin word for "shallow"). Vadose zone, region of aeration above the water table. This zone also includes the capillary fringe above the water table, the height of which will vary according to the grain size of the sediments.

The soil and rock in this zone contains air as well as water in its pores. In some places the unsaturated zone is absent, as is common where there are lakes and marshes, and in some places it is hundreds of meters thick, as is common in arid regions. This study is based on in situ measurements of the soil and the vadose zone (<60 m) in a Mediterranean karst experimental site near Nerja Cave (a show cave in dolomite marbles in southern Spain). Air temperature, relative humidity, and CO 2 concentrations are the main variables measured, especially their variations with depth in a number of boreholes.

Latest developments resulted in establishment of a strong research focus on vadose zone hydrology and engineering hydrogeology. Here, the unsaturated zone (comprising both soil and rock) is investigated with the emphasis of addressing the impact of partial saturation of earth materials on contamination, seepage, drainage and risk posed by land use changes and urban development. Vadose zone infiltration well (VZW) is an important method to implement managed aquifer recharge (MAR) when groundwater table is relatively deep or sufficiently permeable soils at ground and/or sizable land areas for surface infiltration systems are not available.

Stephens, D.B. 2009.

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 systems and waterlogging), requiring mitigation. The vadose (or unsaturated) zone includes soil water, which is immediately available to the biosphere. It acts as a controlling agent in the transmission of water and other substances between various components of the earth system: aquifers, land surface, bodies of water, atmosphere, and so on.

Beginning with atmospheric gas concentrations, vadose zone processes alter soil gas geochemistry in predictable ways on the basis of either reaction stoichiometry or decoupling of gas components.
