Flood control refers to methods used to reduce or prevent flood damage. Some key flood control methods include dams, diversion canals, self-closing flood barriers, river defences, and coastal defences. Dams are designed to control floods by reserving space in reservoirs to store floodwaters. Diversion canals redirect excess water to less impacted areas. Self-closing barriers deploy automatically during floods to protect areas. River defences like levees and weirs hold back high water. Coastal flooding is addressed with structures like sea walls.

2.  Flood control refers to all methods used to
reduce or prevent the worst effects
of flood waters.
 In other words, we can say that Flood control
is the prevention or reduction of the flood
damage.

4.  Many dams and their associated reservoirs are
designed completely or partially to aid in flood
protection and control. Many large dams have
flood-control reservations in which the level of a
reservoir must be kept below a certain elevation
before the onset of the rainy/summer melt
season to allow a certain amount of space in
which floodwaters can fill. The term dry
dam refers to a dam that serves purely for flood
control without any conservation storage
 e.g. Mount Morris Dam, Seven Oaks Dam

6.  Floods can be controlled by redirecting
excess water to purpose-built canals or
floodway, which in turn divert the water
to temporary holding ponds or other bodies
of water where there is a lower risk or impact
to flooding.
 Examples of flood control channels include
the Red River Floodway that protects the City
of Winnipeg (Canada).

8.  The self-closing flood barrier (SCFB) is a flood
defence system designed to protect people and
property from inland waterway floods caused by
heavy rainfall, gales or rapid melting snow.
 The barrier system is constantly ready to deploy
in a flood situation, it can be installed in any
length and uses the rising flood water to deploy.
Barrier systems have already been built and
installed in Belgium, Italy, Ireland, the
Netherlands, Thailand, United Kingdom, Vietnam,
Australia, Russia and the United States.

10.  In many countries, rivers are prone to floods
and are often carefully managed. Defences
such as levees, reservoirs, and weirs are used
to prevent rivers from bursting their banks.

River from flooding Gretna, Louisiana, in March
2005.

in Toronto, Ontario.

13.  Coastal flooding has been addressed with
coastal defences, such as sea walls, beach
nourish
 Tide gates close during incoming tides to
prevent tidal waters from moving upland, and
open during outgoing tides to allow waters to
drain out via the culvert and into the estuary
side of the dike.
