1 1 1 Definition of Vadose Zone

Dr. Selker provides a basic definition for the "vadose zone," and puts it in the context of the critical zone and saturated zones.

Excellent explanation! Also impressed by Dr. Selker's ability to write backward.

thank you sir for clear explanation

[@victoriacorcimaru1731]

thank you so much! Very clear and straight to the point!!!

Is there an identifiable and separate "saturated zone?" No - there can be perched regions that have saturation that are surrounded by unsaturated soil. So please remember that the notion of breaking the wold into "saturated" "unsaturated" "vadose" and "critical" zones are imprecise expressions when applied to large volumes of material. Locally, it is more accurate to discuss saturated and unsaturated locations, but as a "zone" it can often be imprecise.

It's cool that professor can write backward, and I read some definition (e.g. Maliva, R.G., 2019 ) is "unsaturated zone=vadose zone + capillary fringe"
