here is the Definition of springs
Natural water sources Water is the main component of the Earth’s hydrosphere, and it covers 71% of the Earth’s surface, and among these waters, it accounts for about 2.5% of fresh water, and this freshwater is very important for the planet and is especially important for humans, and the forms and shapes of natural water differ On land, some of them are surface waters such as seas, oceans, and lakes, some that come out of the ground, such as underground water, and some that are formed through precipitation such as springs and artesian wells fed by spring water, and in this article, the definition of springs will be introduced.
Definition of springs Springs can be defined as an opening from which groundwater flows to the surface of the earth, and spring water consists of precipitation and its infusion into the layers of soil and porous rocks, such as limestone and sandstone, and then it is stored to become part of the groundwater, and from Then the groundwater moves through the cracks and cracks and becomes trapped between two impermeable layers of rock, and due to an increase in pressure, the water rises to the surface without pumping. These is called artesian wells, and the water of non-artesian springs flows from a high altitude from the ground to a lower altitude and exits in the form of springs. These springs exist in several forms, and they can be classified depending on the temperature of the water into the following:
- Thermal or hot springs: These springs are formed in volcanic areas and in the fractures and folds of rock layers, and these springs have a water temperature much higher than the average air temperature in the surrounding area.
- Geysers: the so-called hot springs, which are springs from which hot water and steam come out in the form of long columns.
- Mineral springs: They are springs that contain quantities of mineral mud dissolved in water.
Types of springs There are several factors that affect the rate of water recharge in springs, including the amount of precipitation, the area of the area in which the groundwater is captured, the size of the capture points, and the size of the outlet of the springs. As the definition of springs has been identified, it is necessary to identify their types, as there are several types of springs, the most important of which are the following:
Infusion springs: These springs are formed from the infiltration of underground water to the surface of the earth, where the water slowly evacuates through the dirt or rocks, and these springs are often found in lowlands or in valleys. Fault springs are the exit of water from faults or cracks in the surface of the earth.
Tubular springs: These springs are one of the largest springs on the surface of the earth, and they are the springs that flow from caves under the surface of the earth and are formed when water passes through limestone rocks, where they work on dissolving these rocks, forming the springs in the form of tubes.
The springs are shaken holes: they are the influx of freshwater from under the sea from coral and sedimentary cover filled with ancient river channels.
Artesian springs: These springs consist of the flow of water due to the difference in pressure in the confined aquifer, where the pressure inside the confined aquifer is less than the pressure outside the aquifer, which leads to the rush of water from the cracks in the ground.
