How do we protect rivers?

Protection of Rivers & Lakes

  1. Prevention of pollution by interception and decentralised treatment of wastewater entering rivers and lakes.
  2. Management of solid waste around the water bodies and catchment areas.
  3. Enhancement of waterfront and catchment areas, such as storm water management, institution of buffer zones and silt traps.

What diseases can you get from flood water?

Flood types

  • Flash floods.
  • Coastal floods.
  • Urban floods.
  • River (or fluvial) floods.
  • Ponding (or pluvial flooding)

What are the benefits of a flood?

Floods distribute and deposit river sediments over large areas of land. These river sediments replenish nutrients in topsoil and make agricultural lands more fertile.

What is fluvial flood?

Fluvial, or riverine flooding, occurs when excessive rainfall over an extended period of time causes a river to exceed its capacity. It can also be caused by heavy snow melt and ice jams. Overbank flooding occurs when water rises overflows over the edges of a river or stream.

How do humans destroy rivers?

Pollution enters the river, sometimes in small amounts, at many different locations along the length of the river. Sewage and effluent are discharged into rivers in some areas. Pollution can lower the pH of the water, affecting all organisms from algae to vertebrates. Biodiversity decreases with decreasing pH

  • Fluvial floods (river floods) A fluvial, or river flood, occurs when the water level in a river, lake or stream rises and overflows onto the surrounding banks, shores and neighboring land.
  • Pluvial floods (flash floods and surface water)
  • Coastal flood (storm surge)

What are the Different Types of Floods?

  • Coastal Flooding. Coastal areas often bear the brunt of severe storms, especially if these have gathered pace over the oceans.
  • River Flooding. River flooding is one of the most common types of inland flood; occurring when a body of water exceeds its capacity.
  • Flash Flooding.
  • Groundwater Flood.
  • Drain and Sewer Flooding.

What is the strongest flood?

  • Coastal floods occur around much larger bodies of water, usually when the tide gets very high.
  • A flash flood is an excessive amount of rain in a short period of time (usually within 6 hours).

How do humans use rivers?

Rivers provide travel routes for exploration, commerce and recreation. River valleys and plains provide fertile soils. Farmers in dry regions irrigate their cropland using water carried by irrigation ditches from nearby rivers. Rivers are an important energy source.
