Based on my study under Dr. Sudhir Kumar Tewatia former scientist with Ministry of Water Resource Development, this presentation is based on the paper with the same title. The Tehri Hydroelectricity project was taken as a case study to critically analyse the effect of dam on climate and environment.
Lakes are helpful in controlling weather and local climate. Lakes are helpful for creating irrigation facilities and recreation. In some places, lakes are good sources for water supply for drinking. Every lake, is unique in terms of its size, morphometry, water availability, water chemistry, physics, hydrology and biology. There are several type, kinds and categories of lakes in the world.
Sand mining is the practice that is used to extract sand.Sand is mined from beaches,ocean beds and river beds.It is used in manufacturing cement,construction purpose etc.

• Ground water contaminates
• Water treatment
• Drinking water quality
Figure 1: At any given moment, 97% of the planet’s water is in the oceans. Only a small fraction
of the remaining freshwater is usable by humans, underscoring the importance of treating our
water supplies with care.
Introduction
It is no secret that water is one of the most valuable resources on planet Earth. Every plant and animal re-
quires water to survive, not only for drinking, but also for food production, shelter creation and many other ne-
cessities. Water has also played a major role in transforming the earth’s surface into the varied topography we
see today.
While more than 70% of our planet is covered in water, only a small percent of this water is usable freshwater.
The other 99% of the water is composed primarily of salt water, with a small percentage being composed of
23

glaciers. Due to the high costs involved in transforming salt water into freshwater, the Earth’s population sur-
vives off the less than 1% of freshwater available. Humans obtain freshwater from either surface water or
groundwater.
Surface water is the water that collects on the ground as a result of precipitation. The water that does not
evaporate back into the atmosphere or infiltrate into the ground is typically collected in rivers, lakes, reser-
voirs, and other bodies of water and is easily accessible.

Figure 2: Water is a renewable source, purified and
delivered across the planet by the hydrological cycle.
Groundwater, on the other hand, is precisely as the name suggests; water located underneath the ground.
This water is stored in pores, fractures and other spaces within the soil and rock underneath the ground’s sur-
face. Precipitation, along with snowmelt, infiltrates through the ground and accumulates in available under-
ground spaces.
Aquifers are areas in which water collects in sand, gravel, or permeable rock from which it can be extracted
for usable freshwater. The depth of aquifers vary from less than 50 feet to well over 1,500 feet below the sur-
face of the ground. The water within an aquifer typically does not flow through as it would through a river or
stream, but instead soaks into the underground material, similar to a sponge. As aquifers are depleted by hu-
man use, they are also recharged from precipitation seeping into the ground and restoring the water level.
However, many times the recharge of the aquifers does not equal the amount of water that has been extract-
ed. If that cycle continues, the aquifer ...
