How can these rivers flow BACKWARDS?

These rivers act like water in a bathtub when someone turns off the tap, but keeps the plug out.

Normally, rivers flow because they're going from high up to low down, just like how water falls from your shower to the drain. But sometimes, water can be pushed back, it's like if you took a hose and blew air into the bathtub, making the water move in the opposite direction.

Imagine two kids playing with buckets of water. One kid pours water into a channel, and another kid uses a big fan to blow the water back toward where it came from. That’s what happens with some rivers, something pushes the water, making it flow backward instead of forward.

It's like when you're drinking from a straw, but someone blows air into your cup from the other side, suddenly, your drink goes up the straw instead of going down! That’s how these rivers can seem to go backwards, not by magic, just by push and pull. These rivers act like water in a bathtub when someone turns off the tap, but keeps the plug out.
