Water does not stagnate in a forest but in a town if it rains heavily.How does it happen
Answers
Answer:
the forest
also acts as a natural absorber of
rainwater and allows it to seep. It helps
maintain the water table throughout the
year. Forests not only help in controlling
floods but also help maintain the flow
of water in the streams so that we get a
steady supply of water. On the other
hand, if trees are not present, rain hits
the ground directly and may flood the
area around it. Heavy rain may also
damages the soil. Roots of trees normally
bind the soil together, but in their
absence the soil is washed away or
eroded.
In a forest, a large amount of vegetation, soil, forest litter, permeable surfaces and humus is present, this allows the percolation of rainwater into the water table and recharge of the groundwater, water easily flows into forest streams and is carried to major rivers, or it is absorbed by permeable surfaces and the moisture-retentive and fertile soil. In towns, a large number of roads, artificially built impermeable structures prevent the percolation of water into the soil. Also, a large amount of rubbish and plastic clogs the drainage pipes, storm water drains and most of the urban streams are clogged and polluted, hence waterlogging easily takes place in towns and major cities but never in natural areas such as forests.
