Question

Gorges are suitable for construction of damscan you tell why this is so?

Answer 1

• Gorges are narrow valleys with steep sides.
• A gorge is almost equal in width at its top as well as its bottom. 
• They are suitable for the construction of massive reservoirs. The natural valleys formed by the gorges are built up with hard rock. 
• The valleys with its steep sides, extensive rocky floors form the natural reservoirs for the dams. 
• Constructing the dams at gorges is less expensive because a little concrete work is needed to form the reservoirs. 
• In these vast and massive reservoirs a lot of water can be stored. 
• Gorges are flood proof. They prevent floods. 
• The waterfalls that falls down from great heights into the gorges can rotate large turbines and generate hydroelectricity in large quantities.
• Thus gorges are suitable for the construction of dams.
