Groundwater Dams

  • Disadvantages of surface dam: A large amount of water evaporates from the water surface. Dam is constructed to store water on the ground surface. Parasites and gcrms appcar. Buildings, cultivated land, forests, etc. are submerged. Disadvantages of surface dam
  • Principle of a subsurface dam and its advantages: Little water evaporates from the groundwater surface. Buildings, cultivated land, forests, etc. are preserved. Reserved water is of high quality. Dam is constructed to store water under the ground. Principle of a subsurface dam and its advantages
Groundwater Dams : Category, Reservoir Dam, Storage Dam
Category Reservoir Dam Storage Dam
Advantages
