This case study examines the Yangtze River Estuary in Shanghai, China. Shanghai has experienced rapid growth as a business and trade center since the 1990s. The tidal range is 4.37 m during high tide and 0.55 m during low tide. Coastal erosion is exacerbated by rising sea levels, land subsidence, dredging of shipping channels, and reduced sediment from damming of the Yangtze River. Proposed solutions include coastal protection measures, functional zoning of the coastal area, and rehabilitation in the Yangtze headwaters.

8.  Sea level is rising at a significant
rate (relative to 1990 will be 15–20,
30–40 and 45–55 cm by years 2000,
2030 and 2050)
 Coastal zone sunk due to the
concentrated exploitation of
underground water
 Effect of digging deepwater
navigation channel in Shanghai
harbour and Yangtze river

9.  Shanghai coastal hit and damaged by
typhoon annually
 No coastal protection significantly defend
Shanghai

10.  Coastal zone develop
20-200 meters
seawards due to the
long term process of
delta development
 Sediment accelerates
caused of Three
Gorges Dam in
Yangtze river

12.  Coastal functional zonation
scheme
 Treating the coastal zone as a
dynamic system embracing both
land and water
 Stronger coastal defend system
 Rehabilitation in Yangtze
headwaters (reduce sediment
volume and contents)
