B) a longer lag time between storms and the onset of flooding
C) an increase in the volume of water entering streams after rainfall
D) a decrease in the likelihood of flash flooding

Question

Quizplus · Accepted Answer

Urbanization results in the removal of vegetation and soil, which reduces the ability of the landscape to absorb and store rainwater. This leads to an increase in surface runoff and the volume of water entering streams after rainfall, which increases the risk of flooding. Additionally, urban development often involves replacing permeable surfaces with impervious ones (e.g. pavement, concrete), further increasing runoff and flooding.
