In terrestrial ecosystems (such as forests, deserts, and savannas), the interactions among vegetation, the land surface, the vadose zone, and the groundwater are the main focus. In aquatic ecosystems (such as rivers, streams, lakes, and wetlands), emphasis is placed on how water chemistry, geomorphology , and hydrology affect their structure

Vadose Zone Hydrology Vadose zone hydrology deals with hydrological processes in the vadose zone, the zone between the soil surface and the groundwater table. Our research covers water flow in soils and segments, water conservation in dryland agriculture, transport and leaching of nutrients and contaminants, transport of inorganic particles ans pathogens.

Hydrology in the zone is complex: nonlinear physical, chemical, and biological interactions all affect the transfer of heat, mass, and momentum between the atmosphere and the water table. [4] The vadose zone is the unsaturated subsurface region between the soil surface and the groundwater table, and it plays an important role in protecting groundwater resources from contamination.

Hence, the vadose zone extends from the top of the ground surface to the water table. Water in the vadose zone has a pressure head less than atmospheric pressure, and is retained by a combination of adhesion, and capillary action.

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. In coarse-grained mediums the fringe may be flat at the top and thin, The vadose zone is the region between ground level and the upper limits of soil fully saturated with water.

Vadose Zone Hydrology describes the elements of the physical processes most often encountered by hydrogeologists and ground-water engineers in their vadose zone projects. It illustrates the application of soil physics to practical problems relevant to the characterization and monitoring of the vadose zone. It includes an introduction to physical processes, including basic flow theory, and VADOSE ZONE HYDROLOGY 1. What is Vadose Zone?

The vadose zone plays a significant role during artificial recharge via the infiltration basin. Its thickness, lithology, heterogeneity, among others greatly affect the recharge efficiency. The main objective of this research is to establish the role of the vadose zone and the impacts of infiltration basin features and vadose zone factors on water distributions. In this work, an ideal
