ANALYSIS ON EVOLUTION OF MODAOMEN OUTLET OF PEARL RIVER ESTUARY BY APPLYING REMOTE SENSING INFORMATION

摘要

The Modaomen outlet is the largest outlet among the eight outlets and the most important flood-discharging channel of the Pearl River Estuary. The water flow and the sediment transport in the channel are extremely complicated due to influences of the runoff, the tidal flow, the south west longshore current and wind waves. This paper analyzes the change of boundary lines of the outlet, the variations of the flow pattern, the flow field and sediment concentration, and the evolution of the Modaomen outlet during the past 20 years by applying the remote sensing information and field hydrological and geographical data.
