What are the dangers associated with a flood?
Flood waters that rise can cause flooding and other health problems. Flooding is the leading hazard to thunderstorms, resulting in more deaths each year than any other. Flood deaths are most frequent when vehicles are driven into flood waters.
What is flood geography?
Floods are the flooding of a river or other water body that is beyond its normal limits. Sea flooding is also a concern for coastal areas. This happens when storm surges or cyclones bring seawater onto the ground.
What happens before a flood?

What are the 5 types of floods?
The 5 Types Of Flooding
- Flash Flooding. Flash Flooding is flooding that occurs within 6 hours, and often within 3 hours, of an intense rain event.
- River Flooding. Heavy rainfall for a long time, often with snowmelt runoff from spring.
- Storm Surge.
How do humans cause flooding?
Man-made activities that cause environmental degradation often increase flooding. These activities include deforestation. Lack of vegetation encourages water flow to the surface, rather than into the soil, increasing surface runoff.
Can floods be predicted?
Flood forecasts require several types data. The rate at which the river stage changes on a regular basis. This can be used to indicate the severity or immediacy of the threat.
How many floods happen per year?

Flood warning system can help to reduce direct losses by:
- the timely operation of flood control mechanisms (e.g. gates, temporary flood defences) preventing inundation of property and land;
- Pre-event maintenance operations to ensure free channel conveyance;
How do flood warning systems work?
A flood warning is a specific, timely information that is based on a reliable forecast and which indicates that high water levels are expected in a given area at a certain time. It is important to convey the warning in a way that encourages people to take action to minimize damage and cost of flooding.
