Answer:
A multipurpose project is that which simultaneously serves several purposes. A dam built across a river often serves more than one purpose at a time and it is termed as a multipurpose project. It comes with some advantages at the same time some disadvantages. The advantages are flood control in flood-prone areas, irrigation facilities, hydroelectricity, check soil erosion etc. On the other hand, it has disadvantages such as, it restricts the natural flow of the river and the sediments are deposited in the river bed, it causes deforestation and disturbs the aqua life of the river.
Explanation:
This is another answer:-
Advantages:
(i) These are the main source of power generation.
(ii) They provide us neat, pollution free and cheapest energy which is the backbone of industry and agriculture.
(iii) These projects control the floods because water can be stored in them. These projects have converted many, ‘rivers of sorrows’ into ‘rivers of boon’.
(iv) These projects are the main source of irrigation and also help in conserving soil.
Disadvantages:
(i) Due to the construction of dams, there are no adequate floods in the river. Because of this, the soil of the downstream region does not get nutrient rich silt.
(ii) Dams also fragment rivers making it difficult for aquatic fauna to migrate for spawning, i.e., to produce eggs.
(iii) It resulted in displacement of local communities.
(iv) The multipurpose projects induced earthquake, caused waterborne diseases.
