How does the rate of runoff changes after development? - answer
In a pre-development watershed, the peak discharge gradually
increases and gradually declines. In a post-development
watershed, the peak discharge increases much faster and to a
much higher amount (2-5x) than pre-development conditions and
declines much more abruptly. This is due to more impervious
cover in post-development and could potentially cause erosion
and flooding.
