Best Answer

Advantages:It helps in generating electricity for the people .Construction of dams helps in this process.Once dams are constructed electricity can be produced at a constant rate.Dams are designed to last many decades and can contribute the generation of electricity for many years.When in use the electricity produced by dams do not produce green house gases.this helps in pollution free environment.

Disadvantages:the release of water from dams during heavy rains can cause floods.Regulating and damming of rivers affect the natural flow of water causing the sediments to settle at the bottom resulting in rockier stream beds.It also fragment the rivers making it difficult for the aquatic fauna to migrate especially for spawning.Also construction of dams are highly expensive.
