What is the water surface?

The bark can be divided into two main zones: an unsaturated zone that contains some water, but has space for more, and a phreatic zone in which all rocks and soil are completely surrounded and filled with water. The water level is a point between two zones in which the Earth is completely saturated. It creates the upper limit of groundwater deposits and can go up and down based on a series of factors. People often approach it with wells because there are more than 20 times more freshwater underground than on the Earth's surface.

shape and location

people often consider the water level a straight line that divides two underground zones, but it is not. In general, it fluctuates in the landscape, in some places it is close to the surface and deepens in others. The shape can also be determined by the surrounding rock or human activity. For example, a large piece of impermeable rocks could avert it and do higher or lower, or people could trigger the collapse of rocks and soils in access to the usable deposit of groundwater called AQUIFER, and change your shape.

Development

A number of factors contribute to the water level. Every time it rains, for example, water runs down the soil layers and increases its level. The drain from lakes, rivers and streams also contributes, as well as melted snow. The rock around the water surface must be porous to be saturated with water. An impermeable rock, such as granite or basalt, cannot collect water, although aquifers are often surrounded by deposits of impermeable rocks that keep the water trapped inside. If the aquifer is completely surrounded by an impermeable rock shell, it may happen under pressure, in which case it will shoot on the Earth's surface if it is clicking on the well.

Get Access

It is usually necessary to dig the pumping well to reach the water level and pull the water to the surface. Placing a well is important because it must be placed in a place where the table is near the surface and an underground bearing is presentka. In some cases, a sharp change in geography may cause the upper soil to coincide with the water supply line that creates a natural spring.

factors affecting water level

The water level may fluctuate significantly depending on the environmental conditions, such as seasonal dryness and tidal changes, as well as human use. For example, a dry charm can cause it to drop significantly. In some places, seasonal fluctuations are common enough to be predicted with a certain degree of accuracy. The water level near the oceans sometimes changes daily along with the tide and increases during the tide and lower as the tide rises.

Sometimes people change water intentionally, usually for industrial purposes. For example, if there is a red deposit below the water level, the mining company can install wells or pumps to remove the water to get into the ore. When the project is completed, the water is usually allowed to flow back into the area, which increases the level again.

threats

The main threats for water levels come from pollution and excessive use. Although it takes a long time for the pollutants to filter out, it is very difficult to remove them as soon as they are there. Common pollutants include drainage from production plants and extensive agricultural projects, wastewater leakage and leaching from landfills. Another common problem is excessive use of water, for example, when the population suddenly increases and requires more water than previously used. This type of exhaustion is particularly common in areas where water is used for industrial production.
