2. Flooding. Rivers can also cause flooding, which can damage property and infrastructure and displace people from their homes. Flooding can also be dangerous for people who are caught in it, as the water can be very powerful and can carry people away.
3. Water pollution. Rivers can also be polluted by industrial waste, agricultural runoff, and sewage. This pollution can make the water unsafe for drinking, swimming, and fishing. It can also harm aquatic life.
