What Happens If The Use Of Groundwater Exceeds The Rate Of Replenishment??
Answer: Groundwater overdraft occurs when the groundwater resources are used up more quickly than they are replenished. Groundwater overdraft can occur for a period of time without noticeable consequences but eventually the aquifer will not be able to keep up with the rate of use as its water storage is depleted.May 19 2020

(i) Due to large and growing population and consequent greater demands for water and unequal access to it. (ii) To facilitate higher food grain production for large population water resources are being over exploited to expand irrigated areas and dry season agriculture.
Which of the following is a disadvantage of large dams and water transfer projects?
1}Dams also fragment rivers making it difficult for aquatic fauna to migrate for spawning i.e to produce eggs. 2}It resulted in displacement of local communities. 3}The multipurpose projects induced earthquake caused waterborne diseases……
What are the effects of overuse of water?
Furthermore in places where clean water is scarce overusing or wasting household water limits the availability of it for other communities to use for drinking cleaning cooking or growing—and thus contributes to disease illness or agricultural scarcity and starvation.
How is water being overused or misused?
Used irrigation water is often contaminated with salts pesticides and herbicides. Industry and urban centres also return contaminated water to both surface and underground water resources. … Dried-up rivers are a good example of the overuse of freshwater resources. Overuse in one place means deprivation in another.
How much is groundwater overuse in India?
Groundwater includes borewells wells pipelines and many others. So in India their overuse is one-third of the country.
What is one possible consequence of excessive withdrawal of groundwater quizlet?
Environmental Issue: excessive withdrawal of water from rivers and aquifers results in falling water tables decreasing river flows shrinking lakes and disappearing wetlands.
What will happen to the water table if groundwater withdrawal exceeds recharge?
Groundwater withdrawal that exceeds recharge really has no impact on the water table. A perched water table is a highly desirable and reliable source of ground water. Karst topography develops in dry climates with very little surface or subsurface water.
Why groundwater is over use?
1. Because of the vast and increasing population and the resultant higher demand for and unequal access to water. 2. Water supplies are being over-exploited to increase irrigated regions and dry season cultivation in order to promote increased demand for food grains for huge populations.
How does overuse of water cause water scarcity?
Water shortages may be caused by climate change such as altered weather patterns including droughts or floods increased pollution and increased human demand and overuse of water. … Water scarcity is being driven by two converging phenomena: growing freshwater use and depletion of usable freshwater resources.
At what rate is the ground water table declining in India?
1–2 m/yearIt has been reported that in many parts of the country the water table is declining at the rate of 1–2 m/year. At the same time in some canal commands the water table rise is as high as 1 m/year. Deterioration in groundwater quality by various causes is another serious issue.

Why is groundwater overused Brainly?
Explanation: Groundwater is a highly overused resource because of the following reasons : … (b) To facilitate higher food grain production for large population water resources are being over exploited to expand irrigated areas and dry season agriculture.
Why is groundwater under serious threat in India?
The ground water is the huge source of disposable fresh water on the planet. … As the ground water level decreases the cost of pumping the water to the surface increases rapidly. Agricultural requires a huge amount of ground water which indeed results in the depletion of the ground water level.
What proportion of the country is overusing their groundwater reserves Class 10?
Nearly one- third of the country is overusing their groundwater reserves.
What effect does the overuse of groundwater have on the environment?
Some human activities such as pumping water into the ground for oil and gas extraction can cause an aquifer to hold too much ground water. Too much ground water discharge to streams can lead to erosion and alter the balance of aquatic plant and animal species.
How does loss of groundwater affect the ground and how can we measure this?
A related effect of groundwater pumping is the lowering of groundwater levels below the depth that streamside or wetland vegetation needs to survive. The overall effect is a loss of riparian vegetation and wildlife habitat. The basic cause of land subsidence is a loss of support below ground.

What are the consequences of increased nitrogen and phosphorus into water systems Site 3 quizlet?
– Too much nitrogen and phosphorus in the water causes algae to grow faster than ecosystems can handle. Significant increases in algae harm water quality food resources and habitats and decrease the oxygen that fish and other aquatic life need to survive.
Can there be development without overuse of groundwater in India?
Yes it is possible to have development without overuse. This is possible if we practice sustainable development which involves using of resources judiciously.
How can we bring development without the overuse of groundwater?
This is possible if we practice sustainable development which involves using of resources judiciously.
