I have used Dan Stephens' book as a textbook in a graduate-level Geology class on the vadose zone. It was ideal. A lot of unsaturated zone books have been published in the last several years, but none of the others was suitable for my purposes.

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. Vadose Zone and Soil Studies Texas Soil Observation Network (TxSON) Texas Soil Moisture Observation Network (TxSON) is an intensively-monitored 36 km grid cell (1300 km2) located near Fredericksburg, Texas, along the Pedernales River and within the middle reaches of the lower Colorado River. 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 systems and waterlogging), requiring mitigation.

This results from the pronounced porosity and permeability contrasts created by local karstification processes of Each flood event launches into the vadose zone a wetting front that propagates down through the vadose zone and recharges the groundwater upon arrival at the water table. The first wetting front of each flood season leaches out soluble salts that have accumulated in the vadose zone during the dry season. 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").

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. Vadose zone The vadose zone extends from the land surface to the water table. The pore space of sediments in the vadose zone contains both air and water.

These processes were found to be controlled by the alluvial sedimentary geology of the vadose zone, which is highly heterogeneous.

Vadose zone The vadose zone extends from the land surface to the water table. The pore space of sediments in the vadose zone contains both air and water. Solution of carbonate sediment or rock occurs in the vadose zone as a result of meteoric water movement. vadose zone beneath the SST WMAs, the IDF, and groundwater have been recently published. The specific subject areas include the geology of the SST WMAs (Reidel and Chamness 2007(d)), groundwater flow and contamination beneath the SST WMAs (Horton 2007(e)), groundwater recharge (Fayer and 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").
