A flood is an overflow of water that submerges land which is usually dry.
The primary effects of flooding include loss of life, damage to buildings and other structures, including bridges, sewerage systems, roadways, and canals.
The Nigeria Meteorological Agency (NIMET) Has issued a red alert regarding flooding in 11 states in Nigeria in the month of August.
The states listed are Akwa Ibom, Bauchi, Benue, Borno, Cross River, Delta, Kaduna, Kwara, Nasarawa, Yobe and Zamfara states.
This was contained in a statement issued on Tuesday, August 9, and released to journalists in Abuja, Sahara Reporter.
A study conducted by Du W, FitzGerald GJ, Clark M, Hou XY on the above topic showed that the health impacts of floods are wide ranging, and depend on a number of factors. However, the health impacts of a particular flood
Flood Control Tips.
Sea/Coastal defence
Sea walls and tide gates have been built in some places to prevent tidal waves from pushing the waters up ashore. In some areas too, sand bags are made and placed in strategic areas to retain flood waters.

Retaining walls in some places, retaining walls levees, lakes, dams, reservoirs or retention ponds have been constructed to hold extra water during times of flooding.
Town planning
It is important that builders acquire permission before buildings are erected. This will ensure that the waterways are not blocked. Also, drainage systems must be covered and kept free from objects thatchock

Vegetation
Trees, shrubs and grass help protect the land from erosion by moving water. People in low-lying areas must be encouraged to use a lot of vegetation to help break the power of moving flood water and also help reduce erosion.

Education
In many developing countries, drainage systems are chocked with litter and people have little knowledge of the effects that can have during a rain. When it rains, waterways and culverts are blocked by massive chunks of litter and debris, and water finds its way into the streets and into people's homes. Education is therefore very important, to inform and caution people about the dangers of floods, what causes floods, and what can be done tominimise
Detention basin
These are small reservoirs built and connected to the waterways. They provide a temporary storage for flood waters. This means in an event of flooding, water is drained into the basin first, giving people more time to evacuate. It can also reduce the magnitude of downstream flooding.
