There are two main types of movement of bedforms in river channels: active and passive. Active bedforms are symmetrical and move without changing shape, while passive bedforms are asymmetric and move with a steep leeward slope. Bedforms are organized into hierarchical complexes, with smaller bedforms moving on larger ones. The type of bedform movement affects bed load transport rates, with active bedforms leading to different transport rates for different orders, and passive bedforms causing complete deposition of sediments on steep slopes. The study focused on understanding how bedforms move in river channels and their impact on sediment transport.
