How does the development of urban areas increase the frequency of floods?

A. If urban population increases, then flooding increases.
B. If urban population decreases, then flooding increases.
C. If urban population increases, then flooding decreases.
D. There is no clear relationship between urban population and the frequency of floods.

Urban development increases flooding due to the creation of impervious surfaces that promote runoff and the reduction of natural drainage systems. As urban areas expand, more water flows rapidly into drainage systems, which can lead to higher flood frequencies. Therefore, an increase in urban population correlates with increased flooding risk. ;

Urban development enhances flooding risks through the creation of impervious surfaces and the loss of natural drainage. As more buildings and roads are constructed, water runoff increases, leading to higher flood frequencies. Therefore, the correct option is A: If urban population increases, then flooding increases.
