Key technologies for large-scale reclamation and protection of tidal flats in coastal areas

With regard to the reclamation layout,reclamation construction,water resources security and environmental protection in the coastal areas of Jiangsu Province,the key technologies for large-scale reclamation and protection of tidal flats are investigated.The interaction between reclamation projects and offshore hydrodynamic processes and its impacts on port resources,sediment distribution and transport of radial sand ridges,stability of tidal flats and offshore sand bars as well as reclamation layout and monitoring techniques of the radial sand ridges are studied.The design standards,methods and construction techniques for reclamation levees,new materials and technologies for levee construction,design and construction of freshwater-storage and diversion projects and safety monitoring,quality inspection and risk assessment of reclamation levees are investigated.The development and utilization of water resources,layout and optimization of freshwater-storage project,optimal allocation and joint operation of water resources and integrated management decision support system for water resources in the reclamation area are explored.The impacts of reclamation projects on environment and their ecological effects,evaluation methods for ecological reclamation,ecosystem reconstruction techniques and monitoring and management modes of ecological environment in the reclamation areas are studied.The key technologies for large-scale reclamation and ecological and environmental protection in the coastal areas of Jiangsu Province are integrated and demonstrated.
