Merits and dimerits of dams

Advantages of dams:

• Electricity is produced at the constant rate with the help of hydroelectricity or hydroelectric power.
• Dams are so designed by well-qualified engineers to span many of the decades and also can contribute to the generation of electricity for about many years or even decades to come.
• The lake or reservoir which forms behind the dam can also be used for the irrigation purpose, water sports or even as other forms of pleasurable activities.Few large dams such as the Bhakra Nangal dam present in India is the tourist attractions.
• The buildup of water inside lake means that the energy can also be stored when needed and also when water is released for producing the electricity.

Disadvantages of dams:

• • Dams tend to be extremely expensive to build and when a decision is taken to build one anyway, it must adhere to a very high standard.
  • And other point to be kept in mind is that since the cost is so high for dam construction, it goes to mean that they must operate for many decades to become profitable enough.
  • You must have heard of the rare flooding related to big dams. But this flooding of large areas of land means that the natural environment is destroyed.
  • Although modern planning and design of dams has reduced the possibility of certain disasters occurring.
