Abstract

Based on measured data of coastline and bathometry, processed by softwares of Surfer and Mapinfo, and combined with sediment loads in different phases at Lijin gauging station, temporal and spatial evolution of coastline and subaqueous geomorphology in muddy coast of the Yellow River Delta is analyzed. The results show that ~68% of sediments were delivered by the Yellow River deposited around the river mouth and in the littoral area from 1953 to 2000. Coastline in different coasts had distinctive changes in response to shifts of river course. Coastline was stable in the west of the Diaokou river mouth. Coastline from the east of the Diaokou river mouth to the north of the Gudong oilfield had experienced siltation, then serious erosion, and finally kept stable with sea walls conservation. Generally, coastline of the survived river mouth of the Qingshuigou river course stretched seaward, whereas the south side of sand spit at the Qingshuigou old river mouth was eroded after the Yellow River inpouring near the position at the Qing 8. The subaqueous geomorphology off the survived river mouth exhibited siltation from 1976 to 1996
