Coastal　wetlands　are　the　most　valuable　ecosystems　on　the　earth　but　facing　severe　degradation　and　losses　owing　to　climate　change　and　anthropogenic　activities.　Many　ecological　engineering　projects　(EEP)　have　been　conducted　to　mitigate　the　degradation　of　coastal　wetlands.　However,　the　geomorphological　impacts　of　EEP　on　coastal　wetlands　have　not　been　well　documented.　In　this　study,　a　method　employed　a　process-based　hydrodynamic　model　and　remote　sensing　(RS)　was　developed　to　evaluate　the　impacts　of　EEP　on　the　geomorphological　change　of　a　prototype　Ramsar　site.　Results　demonstrated　that　RS　can　improve　the　quality　of　bathymetry　data　for　the　numerical　model　with　a　decrease　of　RMSE　of　bathymetry　data　from　0.52　m　to　0.3　m.　RS　data　also　showed　good　capacity　in　trend　detection　of　geomorphological　change　spatially.　Results　showed　the　Chongming　Dongtan　wetland　experienced　erosion　with　an　annual　rate　of-0.035　m/yr　from　2013　to　2016　after　the　implementation　of　EEP.　The　deposition　rate　changed　significantly　in　the　area　within　200　m　of　the　EEP.　It　is　found　that　the　EEP　modified　the　composition　of　vegetation,　sediment　transportation,　as　well　as　substrate　stability,　affecting　the　geomorphological　change　of　coastal　wetlands.　The　study　suggested　that　the　EEP　is　a　direct　and　effective　way　to　restore　the　coastal　habitats　for　waterbirds　from　moderate　anthropogenic　disturbance.　However,　the　modification　of　the　coastal　wetland　ecosystem　by　EEP　will　potentially　increase　the　vulnerability　to　global　climate　change.　Therefore,　Future　studies　are　needed　to　further　evaluate　the　advantages　and　disadvantages　of　EEP　and　identify　a　more　sustainable　approach　for　coastal　management.
