Which of the following accompanies urbanization replacing farms and open areas with cities) ?
A) the discharge pattern of streams in the area does not change
B) runoff occurs more quickly and produces a higher peak flow
C) runoff becomes more spread out in time, increasing the amount of flooding
D) runoff becomes more spread out in time, reducing the amount of flooding
E) none of these
Urbanization
The process by which cities grow or expand, resulting in the conversion of rural areas into urban ones, often associated with a variety of economic, social, and environmental changes.
Peak Flow
The maximum instantaneous discharge of a stream or river at a specific location and time.
Runoff
The flow of water that occurs when excess stormwater, meltwater, or other sources flows over the Earth's surface, often leading to erosion and transporting sediments.
- Identify the elements that affect the incidence of floods and understand how urban development influences runoff and the likelihood of flooding.

Final Answer :
B
Explanation :
Urbanization increases impervious surfaces such as roads and buildings, which leads to quicker runoff and higher peak flow in streams, as water cannot infiltrate into the ground as easily.
