Flooding can occur for a number of reasons. The two main ones are:
1) Too much rain in a short period of time can lead to flash floods. This is worsened if the ground is very dry and unable to absorb the water, or the drains are blocked.
2) If there is a particularly high tide and onshore wind, then the sea can flood low lying areas.
Thank you for contributing. An onshore wind can create something called a storm surge. If you have a low lying area with a shallow coast, then the wind can drive the water into a wave that surges onto a floods the shore. Deep coast lines don’t experience this. It was one of the reasons that Hurricane Katrina was so devastating.
