Generation

River meandering occurs when flowing water erodes the outer banks of curves while depositing sediment on the inner banks, causing the river channel to develop sinuous bends that migrate over time. This process is driven by the higher velocity and erosive force on the outside of bends (where centrifugal force pushes water outward) versus the slower flow on the inside. The degree of meandering is quantified by the **sinuosity ratio = channel length / valley length**, where values greater than 1.5 indicate a meandering river. Meandering is most common in rivers with gentle gradients flowing through easily erodible sediment.
