rivers2 humans effecting drainage.

HideShow resource information

urbanisation, stops infiltration and increases overland flow. it increases evaporation because of the dark surfaces like tar, they also attract heat more meaning more evaporation,,,

deforistation, there is less transporation,, there is more water in the river so there is more flooding, cuz of no storage of water ****ed up by roots of plants,,,

change the vegetation, some trees may **** up more water than others and this could affect the drainage basin because of less or more water being ****ed up by the plants,,,,

ploughing the fields, different ways of ploughing the field, water could run down the plough lines smoothly, or the water cant move cuz the plough lines…
