Three-fourths of the world’s surface is covered with water yet just a little extent of it represents freshwater, that can be put to utilize. Water is an inexhaustible asset.

Multipurpose waterway projects are water assets projects made arrangements for different purposes like water system, hydropower age, water supply for drinking and modern purposes, flood control, and route. These are projects filling an excess, assuming a significant part in the economy and improvement of a country. It is regularly seen that most of the multipurpose waterway projects in India are a mix of water systems and hydropower. Lately, the state-claimed Hydroelectric Power goliath NHPC has consolidated a joint endeavor firm Ratle Hydroelectric Power Corporation Ltd for executing the 850 MW Ratle project in the Union Territory of Jammu and Kashmir. Individuals in old India fabricated numerous pressure-driven structures like dams, fake lakes, tanks, and waterways to store and redirect water for the water system.

A dam is a design that shapes a boundary across a stream to direct the progression of water. Dams can be ordered into a few sorts in light of their level and material utilized for development. We have constructed many enormous dams across significant streams in India. The basic role of dams has forever been to give water to the water system. Present-day dams are additionally used to produce power and to supply water to businesses and families. Dams are utilized to control flooding in flood-inclined regions by managing the progression of water downstream.

The supplies made behind a few dams are utilized for reproducing fish. Dams can likewise be utilized to redirect water into existing more modest streams to advance inland routes. A few dams are well-known vacation destinations and amusement spots. Dams are called multi-reason stream projects because of the numerous ways that they propose to deal with our water assets. A dam makes a colossal repository of water that lowers huge stretches of the encompassing region.

Significant advantages of huge multi-reason projects go to enormous landowners and industrialists, while the nearby, poor, landless individuals have essentially nothing to acquire. Better water system offices draw in ranchers to develop more water-concentrated business crops, prompting over-water systems and expansion in soil saltiness. The development of dams causes biological issues too like square the relocation of fish, disturbing the natural equilibrium, and endangering a few sea-going animal categories.

The unexpected arrival of huge amounts of water from dams brings about enormous scope of flooding in plain regions. Huge dams hinder the free progression of stream water, bringing about questions between various states over water sharing, and furthermore over the sharing of expenses and advantages of the task. Naturalists partner enormous dams with causing seismic tremors, the spread of water-borne illnesses, and the debasement of soil. The greater part of the multi-reason waterway projects in India up to this point have not met their ideal targets.

Principal goals or Advantages of Multipurpose Project 

  • Age of Power: They produce slick, contamination-free, and least expensive energy which is the foundation of industry and horticulture. As indicated by the monetary overview 2005-06 these produce more than 30, 000 M.W. power.
  • Flood Control: These activities control the flood since water can be put away in them. These undertakings have changed over many ‘streams of distress’ into waterways of aid. Model River Kosi. 
  • Soil Conservation: These moderate the dirt since they delayed the speed of the water. 
  • Water system: They inundate the fields during the dry seasons. Many trenches have been dug and they water dry regions.
  • Afforestation: Trees are deliberately planted in and around supplies. This aids in safeguarding “Wildlife” and the regular biological system. 
  • Water Navigation: They accommodate the Inland water routes through principal streams or channels. It is the least expensive method for transporting weighty products. 
  • Fisheries: These give ideal conditions for the rearing of fish. Choose assortments of fish are permitted to develop.
  • Places of interest: These ventures are very much minded and are deductively evolved. So these become the focus of vacation spots. 

Hindrances of Multipurpose Project 

  1. Significant expense: The underlying expense of building the dams is extremely high. It requires a ton of capital and designing abilities and current apparatus which isn’t accessible in India.
  2. Antagonistic Impact on Environment: An immense assortment of vegetation as well as human settlements get lowered into the water of the repository shaped by the dam.
  3. Unfavorable impact on the fruitfulness of the dirt: Due to the development of dams, there are no yearly floods in the river. What’s more, in light of this the dirt of the downstream locale doesn’t get supplement rich “residue”. This decreases the richness of the dirt. 
  4. Unfriendly Impact on amphibian life: Due to the development of a dam on the waterway, the fish in the downstream area do not get adequate supplement material. 
  5. Non-accessibility of water over time: Most of the streams in India stream just for not many months. So water isn’t adequate to construct a dam. 
  6. Questions between various states: States have disagreements about sharing of water, the level of the dam, etc. 
  7. Uprooting of nearby networks: The neighborhood individuals frequently need to surrender their territory and work and their small access and command over assets for the more prominent nourishment for the Nation. 
  8. Change in editing design: They give a guaranteed method for the water systems to ranchers. Because of this, the greater part of the ranchers has changed the editing design moving to water concentrated and business crops. This has prompted salinization of soil promoting natural irregularity. 
  9. Regulating and damming of waterways influence their normal stream causing unfortunate dregs stream and unreasonable sedimentation at the lower part of the supply, bringing about rockier stream beds and less fortunate territories for the stream oceanic life.
  10. Dams additionally part streams making it hard for sea-going fauna to move, particularly for production. The supplies that are made on the floodplains likewise lower the current vegetation and soil promoting its deterioration throughout some stretch of time.

Sample Questions

Question 1: What is a Multi-reason waterway valley project?


Multi-reason stream valley projects are the dams or series of dams that are built across waterways to appropriate water, which is subsequently utilized for different purposes, for example, Irrigation, Navigation, Generation of power, Pisciculture, Tourism, and so forth.

Question 2: For what reason are multipurpose undertakings and huge dams confronting opposition?


As of late, the advancement of multipurpose ventures and huge dams are confronting a ton of public investigation and opposition. That is on the grounds that these huge undertakings cause restoration and resettlement on an exceptionally enormous scope. Individuals who are resettled are not as expected redressed. The relocation of individuals and the normal fauna and verdure is a major expense that is paid for these activities. Developments like Narmada Bachao Andolan and the Tehri Dam Andolan are a few instances of obstruction.

Question 3: Multipurpose ventures and dams have been the reason for some new friendly developments. Name two such friendly developments and compose the basic foundations for these developments?


Protection from these tasks came from social developments, e.g., ‘Narmada Bachao Andolan’ and ‘Tehri Dam Andolan’.

Their main issues were as per the following:

  • At first, the ecological worries were of most extreme significance.
  • Dams have brought about enormous scope relocation of nearby networks.
  • Neighborhood individuals need to surrender their territory and vocation.
  • Nearby individuals don’t profit from such ventures as they are even denied of the neighborhood sources on which they have little control.
  • Numerous settlements and agrarian grounds are lowered and submerged.
  • Recovery of the dislodged people is presently the excellent worry of these developments.
