So tidal waves don't crash into land and cliffs.
If a cliff is being constantly hit with strong currents, it will begin eroding, this is bad because there could be houses on the cliffs, roads, or the cliff may start to erode so much that metres of it fall into the sea. ( 30+ years. )

The above answers point out two different meanings of the word defence. One is the attempt to prevent erosion of the land, and the other is to repel or delay invasion by sea. I suspect from your spelling that you are from the UK, which has been invaded countless times in its history. The last attempt (by Nazi Germany) was just barely repelled.
