curvature-driven-meander-migration

This repository provides a complete, reproducible implementation of a **curvature-informed framework for quantifying river meander migration** from multi-decadal Landsat imagery. The framework bridges the gap between geometric change detection and process-based meander theory by modeling lateral migration as a function of local channel curvature.
