Floods are the most frequent type of natural disaster and it do occur when an over flow of water submerges lands that are usually dry. Floods are often caused by heavy rainfall, rapids snowmelt or a storm surge from a tropical cyclone or tsunami in costal areas.
RAIN FALL :
When there is more rain than the soil can absorb, the excess water quickly runs into rivers and creeks, overwhelming storm drains and ditches and causing a flash flood
WASTE DISPOSAL :
In situations where wastes are disposed into drainage system or water channels, the free flow of water when it rains becomes hindered which leads to an over flow of the water channel which sometimes give rise to flooding.
DEFORESTATION :
Deforestation leads to frequent floods and droughts. It happens because the soil loses its fertility over time and also water holding capacity of the soil gets reduced. In the presence of trees, the soil has a high water-holding capacity and it reduces the risk of floods in the heavy rainfall
NARROW STREAM/RIVER CHANNELS :
Streams flood. Flooding is part of stream behavior. The rate of which streams erode, transportation, and given sediments deeply increases during flooding. A flood happens when the water depth in a stream is more then the depth of the stream channel and goes beyond the stream channel into the surrounding dry land.
SNOW MELT :
Snowmelt is runoff water that occurs as a result of melting fallen snow. When there are significant amounts of packed snow and ice on the ground around your home or nearby, warmer temperatures cause the frozen substances to melt and move, leading to flooding in neighborhoods, streets, fields and bodies of water.
Some common ways or easy steps we could used for flood control are installation of rocks beams,rock-raps, sand bags or maintenance of normal slopes with vegetation or application of soil cement on sleeper slopes and constructions of expansion of drainage other methods includes dyke dans . retention basins or detention.
The primary effects of flooding including as follows : Loss of life , damaging of buildings and other infrastructures such as bridges sewerages system roadways and canals . flood also frequently damages power generation which then has knock on effects caused by the loss of power and many more .
I've observed that most people in platform are occupied in just talking about roadshow and briefly on how their day went.
So i decided to talk about how we could manage flooding our environment and the causes of flood to avoid them from causing harms to humanity i do sincerely thank you all for going through my first post in amazing nature community
