Flood and its impacts

1. Floods

2. Definition A rising and overflowing of a body of water especially onto normally dry land is called flood. Floods are one of the most common natural disasters, and they can have a severe impact on communities and their surroundings.

3. Types of floods There are several types of floods, including flash floods, river floods, coastal floods, urban floods, and more.

4. Flash flood Flash floods are the most common and occur when there is a sudden and intense amount of rainfall that causes water to rapidly accumulate.

5. River floods River floods, on the other hand, happen when a river overflows its banks, usually after a prolonged period of rain.

6. Costal floods Coastal floods occur when water from the ocean or other bodies of water moves inland, often due to storm surges.

7. Urban floods Urban floods can occur due to poor drainage systems and high levels of precipitation .

8. Causes of floods There are several causes of floods, including natural factors such as heavy rainfall, snowmelt, and storm surges. However, human activities can also contribute to floods. Deforestation, poor land use practices, and the lack of construction of dams and levees can all increase the likelihood of flooding . Additionally, climate change is contributing to the frequency and severity of floods around the world .
