This section discusses the behavior of rivers in plains compared to mountain streams, focusing on the meandering nature of rivers and how disturbances lead to changes in their courses.
Behavior of Rivers
Mountain streams are constrained by steep valleys, while rivers in plains have more freedom to shift their banks.
Disturbances like a muskrat burrowing can cause riverbanks to crumble, altering the course of the river.
Slow-moving water deposits dirt, making the water shallower and slower on one side while eroding the other bank.
Meandering rivers exhibit a regular pattern where the length of an S-shaped meander is about six times the width of the channel.
Rivers continue to meander until they loop around themselves, leaving crescent-shaped remnants.
