Bank erosion is affected by both geologic (alluvial stratigraphy, sediment type, tectonics) and geomorphic (channel and valley morphology and history) variables. For example, present meander morphology often provides a means of predicting future rates and locations of bank erosion. Complications exist owing to the lateral and vertical variability of valley alluvium, but nevertheless, geomorphic studies can provide a basis for prediction and control.
