When a river dries up the flora and fauna that are related to that river die or find a new habitat, and a predator of an animal or plant that lived on the river would die or leave as well because its main food source is gone. The watershed of that river would loose a lot of water making the entire area near that river dry up and lose much of its vegetation.

A number of things can happen, depending on the local geology. Sink holes can form where water has receded. The ground level itself may lower over time.

The biggest problem that occurs when ground water, and especially aquifer levels fall is that people have less access to fresh water.

That happens. People adapt. The civilization would need to migrate until they found a new location with the resources they need.
