To control flooding.
Obviously rain, but there are others, like for example, tsunami's may cause flooding, earthquakes can cause river dam's to break and cause flooding etc.
Aswan High Dam

Yes, they can both prevent and cause flooding. If you put a dam in a river, it can flood the area and create a lake.

the dam has increased the annual flooding of the nile river
They increase the flooding because leaves are meant to hold water back. For example think of the Hoover Dam which is almost like a levy. Behind it is a huge lake. If the dam wasn't there the water would be no where near the height that it's currently at. If the Hoover Dam broke it would cause flooding for hundreds of miles. This is why levees increase the destruction caused by flooding. There is more water then what there would be if the levee wasn't there..
