Multipurpose river valley projects are projects that serve several purposes like water for agriculture and industries ,generate hydropower,drinking water ,flood control ,navigation and tourism. main advantages are ; water forirrigation.
High Cost : The initial cost of building the dams is very high. ...Adverse Impact on Environment : A vast variety of flora and fauna as well as human settlements get submerged in the water of reservoir formed by the dam.

(ii) Disadvantages of multi-purpose projects :Obstructs the stream flow, sedimentation, aquatic life and submergence of existing vegetation.
the river Will not be dirty and the animals will also save
lot of people who are they going to sleep will not be able to make it up to sure and save
compare the advantage and disadvantages of multipurpose river project is below.....
Murti river projects are the projects built on the river for multiple purposes such as navigation, electricity,fish, storing water for dry seasons, planting of trees can also be done on either side of the reservoir making it good for tourism.
Some disadvantages of multi purpose river projects are
Change in land use pattern and then excess use and wastage of water, causing water disputes, deforestation, displacing people from their locality where they spend their whole life in the end have to start their life from starting.
this is all what I have multiple projects if you are not satisfied please ask again.

(ii) What is water scarcity and what are its main causes? (iii) Compare the advantages and disadvantages of multi-purpose river projects.
The multipurpose river project have proved both a blessing and a curse.
1.they help in storing water at large amount which can be used for agriculture.
2.they are helpfull in generating hydroelectricity.
3.they help in checking flood.
1.sometimes a lekage in dams from any side can be very harmful for the adjoinig areas.
2.they civer a large area of cultivable land and forest area.
3.some time they causes water worned diseases.
THANK U.I Hope it may helps u
b. Electricity generation
c. Water supply for industrial and domestic purposes
d. Flood control
f. Inland navigation
g. Fish breeding
a. Natural flow of river is affected causing poor flow of sediments also.
b. Excessive sedimentation of the reservoir.
c. Stream beds become rockier.
d. Dam fragments a river thus making it difficult for aquatic fauna to migrate, and for spawning.
e. Reservoirs submerge the existing vegetation and soil leading to its decomposition over time.
f. Deforestation and displacement of local people.
disadvantage of multipurpose project required productivity of adequate water supply

featured snippet from the web
displacement is usually the method that is used to measure the volume of an irregularly shaped object. the object is simply submerged in a liquid and the volume of liquid that is displaced is measured. as an example imagine a 100 ml graduated cylinder with 50 ml of water in it (half filled).
