Advantages of Dam

  • Generation of power: Hydroelectric power is made when water goes through a dam. The power is made by a gadget called a turbine. These are made of metal curls encompassed by magnets. The magnets turn over the curls to deliver power. Turbines are found in dams. The water going through a dam turns the magnets. The energy made is perfect and contamination-free. From this power, we can turn the lights on in our homes.
  • Irrigation facility: Dams and streams store and give water to the water system so ranchers can involve the water for developing harvests. This thought goes way once again into history.

  • Reservoirs: Dams give a great open door to diversion. In building a dam water is put away behind it. This water is known as a repository. Repositories are utilized to store water, particularly during seasons of overabundance. They give exercises like fishing, sailing, swimming, setting up camp, and climbing.
  • Means of transportation: Waterways and streams give an incredible open door to transportation. Barges and ships can explore along a waterway conveying enormous heaps of food and product. This style of transportation is viable in the light of the fact that the heaps conveyed can be very huge.

Disadvantages of Dam

  • Submergence Problem: An enormous region gets lowered because of the ascent in the water levels and transformed into a supply. The proprietors of those terrains must be moved, enough redressed, and very much settled elsewhere. This requires an additional spending plan for arranging a dam development.
  • Dams failure: Dam disappointments might be made either due to many reasons. Dismissing potential powers or unforeseen powers is the primary justification behind the disappointment. The defective plan or event of unforeseen floods can likewise be the reason for disappointment. Not keeping up with appropriate rules during planning and development is likewise a justification behind dam disappointments.

  • Environment impact: Everyday routine patterns of environments experienced in the water (like fish) get impacted because of the development of dams. Their life cycles are adjusted to normal stream natural surroundings and stream systems. By changing the stream, the actual environmental factors are modified.
