IAHR, founded in 1935, is a worldwide independent member-based organisation of engineers and water specialists working in fields related to the hydro-environmental sciences and their practical application. Activities range from river and maritime hydraulics to water resources development and eco-hydraulics, through to ice engineering, hydroinformatics, and hydraulic machinery.

ABSTRACT
In order to provide technical support for effective control, scientific prediction and efficient emergency response on water
pollution accident in Yangtze Estuary, it is very urgent to introduce water quality model and develop DSS integrated with
advanced Information Technology. A depth-averaged 2D hydrodynamics & water quality model for water environment
early warning has been established based on finite volume method. The up boundary of this model is located at Xuliujing
hydrology gauge station, and the down boundary is located on -50 bathymetric contour, and the study region was divided
into 5328 unconstructed cells. Dissolved chemicals and undissolved oil could be modeled. Based upon water quality early
warning model, Yangtze Estuary water quality early warning and emergency response system based on WEBGIS&RIA
has been developed adopting J2EE. ArcGIS Server API for Flex has been selected as the GIS platform, and Google/Baidu
Maps API is applied, which make a geospatial environment coupling local vector data with internet online maps. Adobe
FLEX has been adopted as Rich Internet Application development tool, which balances the system loads better and
beautifies the client pages. This system could provide technical support for the Yangtze Estuary water environmental
protection, including digital information management on water environmental data and decision support for water
environment early warning and emergency response. The core function of digital information management is real-time
monitoring on hydrology and water quality on GIS pages coupling with Google/Baidu online maps. The water environment
early warning is divided into 2 parts: routine warning under the absence of water pollution accident and emergency
warning under the presence of water pollution accident.
