What are terms related to groundwater?

Table of Contents

Aquifer. An underground geological formation of sand, soil, gravel and rock able to store and yield water. Artesian Aquifer.

What are some examples that relate to groundwater?

Existing groundwater can be discharged through springs, lakes, rivers, streams, or manmade wells. It is recharged by precipitation, snowmelt, or water seepage from other sources, including irrigation and leaks from water supply systems.

What are 5 facts about groundwater?

Fun Facts About Groundwater

The amount of available groundwater is 20 to 30 times larger than all U.S. lakes, streams, and rivers combined.
44% of the U.S. population depends on groundwater for its drinking water supply.
53.5 billion gallons of groundwater are used for agricultural irrigation each day.

What are 4 uses of groundwater?

The United States uses 82.3 billion gallons per day of fresh groundwater for public supply, private supply, irrigation, livestock, manufacturing, mining, thermoelectric power, and other purposes.

What is another word for the groundwater flow?

Baseflow. The steady flow component of stream flow that continues for a long time after rainfall has stopped. It is mainly fed by the discharge of groundwater systems and is sometimes called ‘dry-weather flow’.

Is pore related to groundwater?

Groundwater. Groundwater is water that exists in the pore spaces and fractures in rock and sediment beneath the Earth’s surface. It originates as rainfall or snow, and then moves through the soil into the groundwater system, where it eventually makes its way back to surface streams, lakes, or oceans.

What are the three types of groundwater?

What are the types of underground water sources? Infiltration galleries, infiltration wells, springs, and wells are the different types of underground water sources.

Why is groundwater important?

Groundwater helps to keep our rivers free-flowing. Groundwater is used for drinking water by close to 50 percent of the people in the United States, but its largest use is for crop irrigation and agricultural production.

How is groundwater formed?

Most groundwater comes from precipitation. Precipitation infiltrates below the ground surface into the soil zone. When the soil zone becomes saturated, water percolates downward. A zone of saturation occurs where all the interstices are filled with water.

What is underground water called?

Groundwater is fresh water (from rain or melting ice and snow) that soaks into the soil and is stored in the tiny spaces (pores) between rocks and particles of soil. Groundwater accounts for nearly 95 percent of the nation’s fresh water resources.

What is the meaning of groundwater filled bodies?

Groundwater-filled bodies of poorly permeable formations, through which no or almost no flow of groundwater passes. A region of low precipitation, characterized by a severe lack of available water, to the extent of hindering or even preventing the growth and development of plant life.

What is the meaning of man-made groundwater?

Man-made construction to tap groundwater and to conduct it to the surface without the need for external energy (the system is based on flow by gravity). Synonyms: Foggara, qanat, karez, falaj, rhettara, ghail.

What is potential energy of groundwater?

It is a time-dependent variable, varies from point to point within the groundwater domain, and indicates the potential energy of groundwater in any point considered (in metres of water column relative to a selected topographic reference level). Synonyms: piezometric level, piezometric head, hydraulic head, groundwater hydraulic potential.

What is an example of geologic term?

Geological term, indicating an origin related to terrestrial flowing surface water. Example: alluvial sediments or deposits (usually composed of gravel, sand, silt and/or clay), as found within reach of present-day or former stream systems.
