Answer:
What is a Flood?
A flood is an overflow of water that submerges land that is usually dry. Floods are an area of study in the discipline of hydrology. They are the most common and widespread natural severe weather event.
Floods can look very different because flooding covers anything from a few inches of water to several feet. They can also come on quickly or build gradually. To better answer the question of “What is a flood?” we’ll answer what each specific type of flooding event is.
there are five types of floods. They include:
- River flood
- coastal flood
- storm surge
- inland flooding
- flash flood
What is River Flooding?
A river flood occurs when water levels rise over the top of river banks. This flooding can happen in all river and stream channels. This includes everything from small streams to the world’s largest rivers.
Causes of River Flooding
River flooding typically happens for four reasons. They are:
- Excessive rain from tropical storm systems making landfall
- Persistent thunderstorms over the same area for extended periods
- Combined rainfall and snowmelt
- Ice jam
What is Coastal Flooding?
A coastal flood is the inundation of normally dry land areas along the coast with seawater.
Causes of Coastal Flooding
Coastal flooding is typically a result of a combination of sea tidal surges, high winds, and barometric pressure.
These conditions typically come from storms at sea like:
- Tropical cyclones
- Tsunami
- Higher-than-average tides
What is Storm Surge?
Storm surge is an abnormal rise in water level in coastal areas over and above the regular astronomical tide.
Causes of Storm Surge
Storm surge is always a result meteorological storms that cause higher than normal tides on the coast. There are three parts of a storm that create this surge. They are:
- Wind
- Waves
- Low atmospheric pressure
