MORPHOLOGICAL EVOLUTION AND FUTURE DEVELOPMENT OF THE JINSHAN COAST AT THE NORTH BANK OF HANGZHOU BAY
-
Abstract
Based on the bathymetric data collected in 2013-2016 from the Jinshan trough and the north bank of Hangzhou Bay, the future trend of development of the coast is analyzed, in addition to the recent evolution characteristics of Jinshan coastline, through comparison of the changes in spatial sedimentation and erosion patterns, isobathic lines and typical sections along the Jinshan coast in different years. Results show that the east part of the north bank of Hangzhou Bay is under erosion. Sediments derived are now moving into the water to compensate the decrease in sediment flux from the Yangtze River. Land reclamation projects also help the Jinshan beach maintain the sediment siltation or deposition.-
