Degree Type water-phase leaching of contaminants and seasonal water content fluctuations in the vadose zone are limited. The site geology is heterogeneous, with a number of horizontal and different-textured soil layers, as exemplified in Fig. 1.

These processes were found to be controlled by the alluvial sedimentary geology of the vadose zone, which is highly heterogeneous. This heterogeneity should be consid-ered when interpreting soil and deep vadose zone monitoring data and assessing of the leaching potential of agricultural chemicals. The transport 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.

Generally loose, clast- supported, muddy sandy gravel was the predominant sediment type; lenses of matrix-supported gravelly sand occurred sporadically.

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. The vadose-zone sediments within the 300 Area consist entirely of coarse-grained Hanford formation, which was deposited during one or more Pleistocene cataclysmic floods.
