Planform‐asymmetry and backwater effects on river‐cutoff kinematics and clustering by Ielpi, Alessandro, Lapôtre, Mathieu G.A., Finotello, Alvise, Ghinassi, Massimiliano

“…River bends occasionally meander to the point of cutoff, whereby a river shortcuts itself and isolates a portion of its course. This fundamental process…”
