he reason I find these studies so important, is that my property and major portions of the east side of the Calfornia central valley are underlain with cemented hardpan. This means that even the meager seasonal rain that falls, rapidly saturates the shallow sandy surface soils (often only 12 inches deep) and runs off. Even when surface runoff is not apparent, there is significant sub-surface drainage leaving the higher areas to dry rapidly, and the lower areas to be saturated for an extended period - drowning the roots of many species.
Here is a scientific study of "hydraulic redistribution" (HR) by velvet mesquite tree (Prosopis velutina) roots. This species is a legume that produces edible seeds. The study shows that water in relative abundance in surface layers during periods of precipitation is redistributed by the roots deep into the soil for later use in drier periods.

The temperature of the ground drops a great deal when its under the shade of almond trees and allows grass and other plants to thrive even in the summer time.
