Human activities on and near rivers can affect river processes.

Agriculture

  • Farmers often work near rivers because they can use the river's water for irrigation.
  • Livestock and cattle can overgraze, compacting soil, leading to higher surface runoff and a higher risk of flooding.
  • Infiltration into the soil is also lower.

Industry

  • Increased industrial land use means that a larger proportion of surfaces are impermeable.
  • This means there is an increase in surface runoff into rivers, increasing the risk of flooding.
  • Increased industrial land use also causes a reduction in evapotranspiration because there are fewer plants and trees.

Urbanisation

  • Urban areas have a lot of impermeable surfaces like concrete.
  • So, an increase in land use for urban areas means that there are more impermeable surfaces, leading to an increase in surface runoff into rivers.
  • This increases the risk of flooding.
  • Urbanisation also causes a reduction in evapotranspiration because there are fewer plants and trees.
