Soil showing vadose zones.

Vadose Zone Hydrology

Vadose Zone Hydrology Research at WSU

Vadose zone hydrology deals with hydrological processes in the vadose zone, the zone between the soil surface and the groundwater 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 and pathogens. We also investigate spatial and temporal distribution of water in soils and how to measure and quantify water in soils.
