Abstract: This paper introduces the state-of-the-art developments of the integrated model for the Heihe River Basin,the digital river basin model,the human-nature evolution modeling system and the Yellow River numerical modeling system in terms of developing philosophy,mode,quality control,model integration and support system.The systems are used mainly for coupled modeling of water-economic-ecological processes,and are made by integrating of modules in an intensive production manner.Efforts in their development focus on both scientific evaluation of the models involved and construction of environmental facilities suitable for and open to further public developments.Techniques such as multi-sourced data assimilation and parameterization are applied in the systems.Besides,the paper shows such technical problems needing to be addressed in the future as modeling uncertainty,model evaluation,high efficient save of,access to,and visualization of complex data,model integration for cloud computation of the large-scaled processes of multi-disciplinary variables,3D/4D variational data assimilation,experimentation based on interactive digital and physical models for rivers,water cycling,transport of multiple agents and modeling techniques.
