Monitoring station network planning and information system construction for salt-tide in Yangtze River Estuary

Along with the rapid economic development of Shanghai City,the freshwater resources cannot meet the demands and new freshwater resources are needed to be developed.Shanghai City is located at the estuary of the Yangtze River and the river can provide abundant freshwater for the city,but the salt-tide intrusion affects its quality.In order to establish a salt-tide controlling and supporting system,the feature and law of saltwater intrusion in the Yangtze River Estuary should be further studied,with a combination of research requirement,the monitoring contents about salt-tide are put forward and the layout of monitoring station network is determined initially based on the present monitoring status.After that,the construction of saltwater intrusion information system is discussed deeply.
