Subsequently, question is, can 1 inch of rain cause flooding? If a low-lying area near a river near you usually gets about 50 inches of rain a year, you might think "Well, that is about 1 inch per week, so that won't cause any flooding".

Subsequently, one may also ask, how long does it take for flood water to go down?

Flash flooding occurs within 6 hours of the rain event. Flooding is a longer term event and may last a week or more.
