How Rivers Are Formed Rivers start as very small streams and gradually get bigger as more and more water is added Heavy rains and spring meltwater add so much water to some rivers that they overflow their banks and flood the surrounding landscape. The water in rivers comes from many different sources. Rivers can begin in lakes or as springs that bubble up from underground. Other rivers start as rain or melting snow and ice high up in the mountains. Most rivers flow quickly in the steeply sloping sections near their source. Fast moving water washes away gravel, sand and mud leaving a rocky bottom. Rivers flowing over gently sloping ground begin to curve back and forth across the landscape. These are called meandering rivers. Some rivers have lots of small channels that continually split and join. These are called braided rivers. Braided rivers are usually wide but shallow. They form on fairly steep slopes and where the river bank is easily eroded. Many rivers have an estuary where they enter the ocean. An estuary is a section of river where fresh water and sea-water mix together. Tides cause water levels in estuaries to rise and fall. Problem 2. 3. Suggestion to fix it
