1. This type of flood is the most deadly - Flash floods. Flash floods are the most deadly because they are unpredictable and happen suddenly, before people can prepare themselves.

2. This type of flood is often caused by slow-moving thunderstorms - Flash floods. Flash foods can occur in areas that are not prone to flooding if an excessive amount of rainfall takes place in a short period of time. Slow-moving thunderstorms tend to cause this kind of rainfall.

3. This type of flood is most common in July - Flash floods. Flash floods are very common in the mid-summer, because the air is moist, and the wind is slow. This enables the development of slow-moving thunderstorms.

4. This type of flood is often enhanced by snowmelt - Widespread floods. Because snow usually accumulates over a large area, if it melts, it can turn into runoff water that also covers the same large area. This essentially becomes a widespread flood.

5. This type of flood is often caused by storm surge - Coastal floods. When the sea level rises because of wind and atmospheric conditions, a storm surge occurs that can eventually cause a coastal flood.

6. This type of flood is most common on small rivers and streams - Flash floods. More specifically referred to as overbank floods. These floods occur when the amount of water in the stream is excessive and becomes runoff.

7. This type of flood is most common in mountainous regions - Flash floods. In sloped terrain, water might accumulate under dry soil.

8. This type of flood occurs along major river systems, like the Mississippi. - Widespread floods. Major rivers carry an enormous amount of water and are usually located in very flat areas. They are also part of watersheds that can have several rivers flooding at the same time.

9. This type of flood is the most costly - Widespread floods. Widespread floods usually develop slowly but last for a long time: days, weeks, or even months. The durability causes more damage and higer costs.

10. This type of flood occurs along major river systems, like the Mississippi. - Coastal floods. Nor'easters cause coastal floods just like their tropical "cousins", hurricanes.
