Download Water in the unsaturated zone


The unsaturated zone, often called the vadose zone, is the portion of the subsurface above the water table. It contains, at least some of the time, air as well as water in the pores. Its thickness can range from zero, as when a lake or marsh is at the surface, to hundreds of meters, as is common in arid regions. These models helped improve our understanding of unsaturated-zone processes and develop sustainable land-management practices. Aimed at professional soil scientists, soil-water modelers, irrigation engineers etc., this book discusses our progress in soil-water modeling. Above the water table - the soil and rock in this zone contains air and water. Some places don't have unsaturated zones, like marshes, and other places have unsaturated zones .

unsaturated zone, immediately below the land surface, contains water and air in the open spaces, or pores. The saturated zone, a zone in which all the pores and rock fractures are filled with water, underlies the unsaturated zone. The top of the saturated zone is called the water table (Diagram 1). The water table may be just below or hundreds.
