The plain answer is that they end when they run out of energy. So they simply stop then. But there are all kinds of whirlpools caused by all kinds of things. Which means there are all kinds of ways whirlpools can get and lose their energies. For example, there are whirlpools in your bathroom sink when you open the drain. They stop when the water is gone from the sink and so there is no longer a force of gravity acting on water to cause the whirlpools. There are whirlpools in the wake of a ship. They're called eddies, but they are still whirlpools. They stop when the ship stops because they were getting their energies from the ship's motion. Similarly there are whirlpools in running streams and rivers, they might stop if there is a change in flow or the river runs dry. So there you are. Whirlpools stop when they run out of energy.
Irregularities in basin and channel bottoms usually cause whirlpools in rivers and lakes.
