What causes coastal flooding?

Coastal flooding happens when water from the ocean or nearby rivers moves into areas where people live near the shore.

Imagine you're playing in a bathtub with your toys. When you turn on the tap, water flows in and covers your toys, that's like flooding. Now imagine the tub is a coast, and the water is from the sea or a river.

Sometimes, when it rains a lot, rivers get full and push their extra water toward the sea. That’s like turning on the tap really fast, too fast!

Also, if there's a big wave, like one from a storm, it can splash up and cover the land near the coast, just like when you jump into the tub and make a big splash.

If the water is already high because of the tide or rain, and then a storm hits, that’s like turning on the tap and jumping in, double trouble!

So coastal flooding is like when too much water comes in from the sea or rivers, and it covers the land where people live. It's not magic, it's just water doing what water does when it gets excited!
