Which feedback maintains braid formation distal to alluvial megafans?

💡 Explanation

Aggradation causes further channel divergence via avulsion: decreased slope follows aggradation, and this positive feedback loop increases braid channel formation, rather than channel stabilization from vegetation because channel instability dominates.
