From: Large-Scale Channel Migration in the Sittang River Estuary
Channel-migration subprocesses. Lateral migration of tidal channel proceeds through meeting/parting of flood and ebb channels, which are evasive with each other. (a) Flood and ebb flows form dominant channel on alternate sides, and rapid bank erosion occurs during this phase. (b) Channel meanders during bank erosion. Ebb flows no longer follow it from opposite side and thus create new, separate channel. (c) Flood flows shift to new channel as ebb flows deepen it. Channel along bank is filled out without active ebb flows. (d) Flood and ebb flows separate from each other as meander channel migration proceeds. Subsequently, flood flows shift to ebb channel to form dominant channel along other side of central basin. Illustrations were created using Microsoft Powerpoint 2016.
