Some methods of flood control have been practiced since ancient times. 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).

Answer:
Floods can happen during heavy rains, when ocean waves come on shore, when snow melts too fast, or when dams or levees break. ... Flash floods occur when excessive water fills normally dry creeks or river beds along with currently flowing creeks and rivers, causing rapid rises of water in a short amount of time.
Ways to control floods:
A residential flood control system is any way(s) used to systematically reduce the risk of damage to a home or basement due to flooding. This flooding can be from basement cracks, floor drains or floors, through an overwhelmed catch basin, or even worse, up through the connection to the sewer system.
