Floods are described as bodies of water that occupy ground that is ordinarily dry. They are widespread natural phenomena that can affect millions of people worldwide. Floods often occur in densely populated areas with high agricultural reclamation, concentrated rivers and lakes, and abundant rainfall, such as warm temperature zones and subtropical zones in the northern hemisphere.
There are two types of flooding problems: urban flooding and flash flooding. Urban flooding is described as the inundation of land or property in a built environment, particularly in more densely populated areas, caused by rainfall overwhelming the capacity of drainage systems such as storm sewers. Flash flooding, on the other hand, typically occurs in remote or mountainous areas, causing 70% of loss of life due to flood disasters. Landslides, mudflows, and debris flows caused by the sudden onset of intense storms account for many of these casualties.
Floods usually result from natural causes but can also be caused by man-made factors, resulting in huge damage to life and property. There are many different causes leading to flooding; some prominent among them include massive rainfall, inadequate drainage systems, and ineffective infrastructure design during heavy rains. Additionally, in cases of heavy rainfall, systems may fail, leading to floods. People living along rivers are always at risk of life-threatening situations from overflowing rivers. Moreover, during heavy rainfall, dams built may begin to collapse, exacerbating flood situations for people living around them. Deforestation is also a major cause of man-made flooding, as trees prevent soil erosion and loss of crops.
The government should take measures to reduce flooding by building dams, detention basins, implementing education and awareness programs related to floods, and establishing building regulations for new developments.
