[12], Windrows are the piling of erosion-resistant material on a river's bank, where if buried, they become known as trenches. [3] Although each mode of failure is clearly defined, investigation into soil types, bank composition, and environment must be clearly defined in order to establish the mode of failure, of which multiple types may be present on the same area at different times.
