Why Siltation is a huge problem for dams?
Water flowing in streams or rivers has the ability to carry particles and to deposit materials. This phenomenon of sediment transport can substantially affect the design of reservoirs. Many cases have been recorded where reservoir siltation rendered water storage structures useless in less than 25 years.
What are the disadvantages of building dams?
Damming of rivers and regulating their flow result in excessive sedimentation at the bottom of the reservoir. This may hamper aquatic life and their migration to other water bodies. Building of dams result in the submergence of land and vegetation. This results in the decomposition of vegetation.
What are the problems faced by building big dams?
