use of chemical fertilisers.
sambhar lake has the highest water salinity in India
pakistan has signed the indus water treaty with india. :)
India contains 16% of the worlds total water supply.
Ancient India depended on their water surroundings because they had to drink water from the water wells/waterholes.
What? How many water meters are in the world, or how many water meters are in India? Or maybe how many meters of water in the world border India? I'm wondering when any of that information would come in handy to 99% of the population.
what factors have led to reduction of water table level in the field
pumping water from aquifers
The water table.
An increase in precipitation.
An increase in precipitation.
One factor that could account for a drop in the water table is temperature. If temperatures are too warm the water may be evaporating.
An increase in precipitation or a decrease in water usage can lead to a rise in the water table. This allows more water to percolate down into the ground, causing the water table to increase.
less rain and snow
An increase in precipitation.
The slope of the water table is called the hydraulic gradient. This gradient represents the rate of change in water table elevation over a specific distance. It is an important factor in determining the direction and velocity of groundwater flow.
One factor that could account for a rise in the water table is increased precipitation or rainfall in a given area. Higher rainfall can lead to greater surface water infiltration into the ground, replenishing aquifers and elevating the water table. Additionally, reduced evaporation rates due to cooler temperatures or changes in land use, such as less urbanization and more vegetation, can also contribute to this rise.
It depends on the cross section and depth of the well as well as the depth of the water table. Another factor is the amount of water that is being drawn from the well.
