There are at least three reasons to use sensors networks in vadose zone hydrology. First, these networks will improve the spatial and temporal coverage of soil moisture measurements. This information may then be used for improved characterization of hydrological fluxes, for calibration and validation of remote sensing data, and for development of upscaling and downscaling techniques.

Vadose Zone Hydrology describes the elements of the physical processes most often encountered by hydrogeologists and ground-water engineers in their vadose zone projects. It illustrates the application of soil physics to practical problems relevant to the characterization and monitoring of the vadose zone.

Vadose zone hydrology

Spatial variability in soil properties such as available water capacity and hydraulic conductivity affect the processes of infiltration, runoff, and deep percolation. 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. In coarse-grained mediums the fringe may be flat at the top and thin, whereas in finer grained material it will tend to be higher and may be very irregular along the upper surface. The vadose zone is the region between ground level and the upper limits of soil fully saturated with water. Hydrology in the zone is complex: nonlinear physical, chemical, and biological interactions all affect the transfer of heat, mass, and momentum between the atmosphere and the water table.

Our research covers water flow in soils and segments, water conservation in dryland agriculture, transport and leaching of nutrients and contaminants, transport of inorganic particles ans pathogens.

The dry or moist sediments below the surface soil layers form the unsaturated zone (also called the vadose zone). The depth of the unsaturated zone can vary from zero (where groundwater reaches surface water) to more than 100 m (in some deserts).
