What Are Some of the Ways That Urbanization Can Change

Question

Examlex · Accepted Answer

The Answer is Student answers should resemble the following: Before an area experiences urbanization,much of the rainfall and runoff either soaks into the ground or gets taken up by vegetation.As a result,the amount of water that enters streams is less than what fell as rainfall,and there is a significant time delay between the rainfall and any increase in stream discharge.Urbanization is when natural surfaces are covered by impermeable materials such as roads,buildings,parking lots,and sidewalks.Rainfall and runoff are forced to go into storm drains and culverts,and do not have the chance to enter the ground or be taken up by plants.More of the total rainfall thus enters the stream (making a flood more likely for a given amount of rain),and there is less time lag between the rainfall and the increase in discharge (giving people less notice to prepare for a flood).
