Flash floods occur when heavy rainfall exceeds the ability of the ground to absorb it. They also occur when water fills normally dry creeks or streams or enough water accumulates for streams to overtop their banks, causing rapid rises of water in a short amount of time.
Why does water fall during a storm?
Base flows are lower than they used to be As the amount of impervious surfaces increase in a watershed, the amount of water that infiltrates into the ground when it rains decreases, thus, there is less water in the surrounding ground to supply water for base flow.
What is a method of controlling flooding?
Some methods of flood control have been practiced since ancient times. 1. These methods include planting vegetation to retain extra water, terracing hillsides to slow flow downhill, and the construction of floodways (man-made channels to divert floodwater).

How much water can a storm drain hold?
The answer is definitely “yes”. A typical outdoor trash can holds 32 gallons. If you capture the rainfall runoff from a storm that just produces 1/10th of an inch of rain onto a 20 by 30 foot roof, you end up with a full 32-gallon container full of water, with 5 gallons left over.
How many raindrops fall in a storm?
Once square mile is 4014489600 square inches, so we end up with 4014489600 cubic inches of rain, or 17378700 gallons (which is a lot!). There are 90,921 drops of water in one gallon, so multiplying all together… Roughly 1,580,088,782,700 drops of water will fall. Or about 1 1/2 trillion drops.

Why does water flow less during a storm?
As the amount of impervious surfaces increase in a watershed, the amount of water that infiltrates into the ground when it rains decreases, thus, there is less water in the surrounding ground to supply water for base flow.
