Imagine flying over a lowland river after school, it looks like a giant ribbon bending left and right. Those bends are not random: they follow a pattern and they change over time. Today you’ll learn how a river ‘carves and builds’ at the same time, erosion on one side, deposition on the other. If you can explain why one side erodes and the other deposits, you can answer most meander questions.
