Vadose zone - Wikipedia
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").
Vadose Zone - an overview | ScienceDirect Topics
The vadose zone is frequently called the unsaturated zone, and sometimes the zone of aeration, as its pore space usually contains air as well as water. The vadose zone extends from the land surface to the water table (the lowest water table if there is more than one).
Vadose zone | Soil Moisture, Groundwater Flow & Permeability
vadose zone, region of aeration above the water table. 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.
USGS Groundwater Information: Unsaturated Zone
The unsaturated zone is the portion of the subsurface above the groundwater table. The soil and rock in this zone contains air as well as water in its pores. In some places the unsaturated zone is absent, as is common where there are lakes and marshes, and in some places it is hundreds of meters thick, as is common in arid regions.
4.1 The Shallow View – Groundwater in Our Water Cycle
The zone above the capillary fringe is called the unsaturated zone because soil pores are only partially filled with water; it is also called the vadose zone (Figure 10).
Vadose water | U.S. Geological Survey - USGS.gov
2009年12月27日 · Vadose water is subsurface water between the land surface and the saturated zone below the water table. The vadose (or unsaturated) zone includes soil water, which is immediately available to the biosphere.
Vadose Zone Journal - Wiley Online Library
Vadose Zone Journal publishes interdisciplinary fundamental and applied research on the vadose zone, promoting science-based decision-making and sustainable management.
USGS Unsaturated Zone Flow Project
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.
Understanding and Predicting Vadose Zone Processes
2019年9月1日 · The vadose zone (often called the unsaturated zone) is commonly defined as the geologic media spanning from the land surface to the groundwater table of the first unconfined aquifer (Stephens 2018).
Fiber-optic seismic sensing of vadose zone soil moisture dynamics
2024年8月5日 · Here, utilizing pre-existing fiber-optic cables as seismic sensors, we demonstrate a fiber-optic seismic sensing principle to robustly capture vadose zone soil moisture dynamics.
