Ironically, the dams that were constructed to control floods have triggered floods due to _____.

  1. Poor construction

  2. Sedimentation in the reservoirs

  3. Submergence of land

  4. Mechanical failures
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation
  • A dam is a man-made structure built across a river.
  •  Most dams are built to control river flow, improve navigation, and regulate flooding.
  • Dams are made from earth, rocks or concrete and are usually constructed on rivers to store the water in a reservoir.
  • All rivers contain sediments: a river, in fact,can be considered a body of flowing sediments .
  •  When a river is stilled behind a dam, the sediments it contains sink to the bottom of the reservoir. 
  • The amount of sediment carried into a reservoir is at its highest during floods .
  • The construction of a dam blocks the flow of sediment downstream,  and increased sediment build-up in the reservoir.
  • This triggers floods,
