We combine airborne light detection and ranging data with historical aerial photos. We relate floodplain formation with vegetation patch characteristics. This methodology reconstructs timing of channel incision of three braided rivers. Long-term changes play a significant role in explaining vegetation mosaics. Presence of shrub patches is a good indicator of incision periods.
