The diagram below shows the water cycle in both forested and urban areas. Summarise the information by selecting and reporting the main features and make comparisons where relevant.

The diagram illustrates the

water

cycle in forested and city

areas

. Generally,

this

process is cyclic and composed of six stages in both

areas

, four of them take place above the

ground

and two are under the

ground

.

This

cycle starts from the precipitation process, which remains the same in forested and urban places. After rainfall, there is the process of infiltration, where

water

propagates the permeable topsoil and less permeable subsoil on rocks. As

water

reaches the

water

table, it couples with baseflow and flows to the

ground

, where it couples with

runoff

. In urban

areas

, the processes of infiltration and the level of baseflow are reduced and lead to increased erosion. The stages above the

ground

include evaporation, transpiration and

runoff

.

While

transpiration in forested

areas

remains the most significant amount of

water

, which returns to the air, evaporation and

runoff

are the least considerable.

However

, these stages in urban places are reduced, and there is an increase in pollution of

runoff

.
