What effect do deforestation have on water?

Answer 1

Without vegetation and tree roots to help hold the soil together, it can weather away by wind, water (rain, streams, etc) much more easily. Less topsoil makes it easier for water to collect, for topsoil absorbs water, but compact clay-like ground does not (or at least not easily or quickly). Thus the water can build up and eventually cause a flood.

Incidentally, this is part of the reason for the danger of flash floods in desert or arid regions. The water builds up faster than it can be soaked up or drained away.

Answer 2

Deforestation can lead to reduced water quality and quantity in rivers and streams. Without trees to absorb and retain water, there is increased surface runoff and erosion, which can cause sedimentation and pollution in water bodies. It can also disrupt the water cycle, leading to altered rainfall patterns and potentially contributing to local water scarcity.

Answer 3

Deforestation affects rivers by causing erosion that often leaks into rivers. This can change the pH or even the pollution levels of the rivers drastically.

Answer 4

Deforestation has to do with the land. SO therefore it has no affect on the water

Answer 5

cutting down tree's affect floods because the tree's are our nature and by cutting down tree's to make paper it can effect many things :h :) (3

Answer 6

Urbanisation is when the flood water cannot go through the concrete because it is impermeable and deforestation is when trees are being cut down.

Answer 7

It causes floods because all the trees are gone, leaving a clear, easy to navigate path for which water can flow.
