It is thought that the channel bay line evolution processes can be divided into four stages. The first stage is soon of the sea level stable when the bayhead mountines are eroded and developed abrasion geomorphy and the productive materials were transport into the bay deposition by the tidal current and wave current and were reworked into gravel dams. The second stage is characterized by the fluvial output sediments and eroded sediments mixed deposition in channel bay and developed marine accumulation plain and sand riges in the plain under the wave reworked. The third stage developed clay silt marine accumulation plain under the action of the channel current and the wave action is very limited. The fourth stage is marked by human being reclaim which result in the channel bay filled and evoluted into a strait arce coast.
