Due to its weight. They are more suitable for narrow valleys with steep side slopes and strong foundation because of more weight. They are strong and costlier than earth dam. (iii) Rock fill Dam: A rock fill dam is like a combination of the two mentioned above. The inner segment consists of rock pieces, boulders etc. with an impervious outside membrane. Sometimes it has an impervious earth core to check the seepage. They are less strong than the gravity dam and used for limited heights only, particularly when the rock pieces are abundantly available.
The area under submergence is generally Water Pollution 21 forest and the if the valuable forestland with trees and other vegetations are submerged it is an actual loss to the environment. The other details about this are given in the chapter on Environmental Impact Assessments. 4 SUBSURFACE OR UNDERGROUND SOURCES The rainwater that gets infiltered and percolated inside the earth to form a uniform water surface is known as the ground water. This water is comparatively pure because of the natural filtration as it passes through the soil.
The ground water is deep at places of scanty rainfall. Generally, the salts available in the soil gets dissolved in the ground water and they make it unfit for human consumption. Fluoride is the main culprit. ). In other states also, the ground water has generally more than the permissible amount of dissolved solids. Making water free of dissolved solids is very costly. So it is wise to construct some obstruction in uselessly flowing water to make it useful. Otherwise, the water will either ultimately flow into the seas and oceans, or will evaporate into the atmosphere.
