What is the process of movement downwards of vadose water called?

Explanation: Vadose water, which occurs from surface downwards up to a variable depth and is in a state of downward movement under the influence of gravity. Explanation: The movement of vadose water is commonly described as infiltration.

How does water get into an aquifer?

An aquifer is a body of porous rock or sediment saturated with groundwater. Groundwater enters an aquifer as precipitation seeps through the soil. It can move through the aquifer and resurface through springs and wells.

What is the area above the aquifer called?

The upper surface of this water-filled area, or “zone of saturation”, is called the water table. Wells can be drilled into the aquifers and water can be pumped out. Precipitation eventually adds water (recharge) into the porous rock of the aquifer.

What is an aquifer recharge zone?

The term “aquifer recharge area” refers to places. where water infiltrates into the ground and replenishes. the aquifers. As the water seeps into the aquifers, contaminants from aboveground activities can go along.

What is vadose water?

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.

Which vadose water zone is also called the zone of saturation?

Groundwater zone starts from the bottom edge of the capillary zone. In this zone, all the pores of the soil matrix are filled with water. This zone is also known as zone of saturation.

Where is the aquifer located?

Aquifers Overview Unlike surface water, which is mostly found in the northern and eastern parts of the state, aquifers are widely distributed throughout California. Additionally, they are also often found in places where freshwater is most needed, for instance, in the Central Valley and Los Angeles.

What is an aquifer where are aquifers usually found?

Groundwater can be found in a range of different types of rock, but the most productive aquifers are found in porous, permeable rock such as sandstone, or the open cavities and caves of limestone aquifers.

What is land that drains into a river?

A watershed is an area of land that drains or “sheds” water into a specific waterbody. Every body of water has a watershed. Watersheds drain rainfall and snowmelt into streams and rivers.

What is a confined aquifer?

A confined aquifer is an aquifer that is bounded above and below by confining beds. Confined aquifers generally occur at significant depth below the ground surface.

What is the transition zone of an aquifer?

The contributing zone of an aquifer includes all watersheds that feed runoff into rivers and streams that flow over the recharge zone. In the transition zone, geologic features such as faults and fractures present possible avenues for contaminants in surface water to reach the aquifer.

What is the artesian zone of an aquifer?

An artesian aquifer is a confined aquifer containing groundwater under positive pressure. An artesian aquifer has trapped water, surrounded by layers of impermeable rock or clay which apply positive pressure to the water contained within the aquifer.
