1) underground water is being withdrawn and used constantly by people for cooking, drinking etc.
2) in urban areas, where the land surfaces are concrete and tarmac (non porous and very low permeability), water will not be able to infiltrate through, thus causing the water flows in the soil layer to decrease. Percolation, throughflow and baseflow are all decreased due to lack of water. This will cause the water table deep down in the soil layer to decrease in height, leading the lesser water being stored underground.
Hope this answers your question!
What else can I help you with?
What happens to the water level when boiling?
The water level DECREASES because: As you boil water, the bonds between water molecules are broken and they turn into gas. The water vapor rises leaving less liquid water then there was before.
Why does the sun cause swelling of the water in the body?
The sun causes dehydration by evaporating moisture from the skin, which can lead to a decrease in the body's water content. This decrease in water content can trigger a compensatory mechanism in the body that causes an increase in water retention, leading to swelling.
What causes daily changes of water level on earth?
The evaporation reduces the water level. The process of precipitation increases the level of water on earth.
How does heat effect pH level?
Heating pure water the pH decrease.
What causes the decrease in the density of warming water?
The decrease in the density of warming water is mainly caused by thermal expansion, which occurs when water heats up and molecules spread apart, making water less dense. Additionally, melting ice caps can contribute to a decrease in the density of water as fresh water mixes with seawater, further lowering its density.
What should be done to increase the level of underground water and wells?
Nothing can be done to increase the level of underground water. That is an entirely natural situation.Nothing can be done to increase the level of underground water. That is an entirely natural situation.
Why does the water level in the toilet bowl decrease?
The water level in a toilet bowl decreases when there is a blockage in the plumbing system, a faulty flapper valve, or a leak in the toilet tank. This causes water to slowly drain out of the bowl, resulting in a lower water level.
When the lake water evaporates the water level usually?
The water level usually decrease.
What do you call the upper level of underground water?
the water table
Which gas causes a decrease in pH level of water?
Carbon dioxide because it is an acidic oxide (weak)

What causes decrease of density in warming water?
As water warms, the thermal expansion effect causes the water molecules to spread out, leading to a decrease in density. This is because warmer water is less dense than colder water. The increase in temperature causes the water molecules to move faster and spread out, resulting in a decrease in the mass of water within a given volume.
What causes hole in the ground caused by underground water?
a hole
The level at which all spaces inside underground rock are filled with water is called what?
The level at which all spaces inside underground rock are filled with water is called groundwater. It contains 21% of the world's freshwater supply.
What makes the water table drop?
The water table can drop due to factors such as excessive pumping of groundwater, prolonged drought, and changes in land use that reduce infiltration of water into the ground. These can lead to a decrease in the amount of water stored underground, resulting in a drop in the water table level.
Why does the sun cause swelling of the water in the body?
The sun causes dehydration by evaporating moisture from the skin, which can lead to a decrease in the body's water content. This decrease in water content can trigger a compensatory mechanism in the body that causes an increase in water retention, leading to swelling.
What does the water table and water wells have in common?
"Water table" means the level of water underground. So when you dig a well, you have to dig down at least to that level.
