Research Progress of Watershed Hydrological Model

Watershed hydrological model is an important tool for studying drainage basin hydrology and water resources management.System theoretical model,conceptual model and physical model were introduced.Their application development and existing problems were presented.In future,the study hotspot will focus on: strengthening the analysis of models’ physic basis,improving the parametric optimization,perfecting the models’ framework,enhancing the simulation authenticity and applicability of distributed model;the technologies of 3S,DEM,ANN etc,will be involved into model,so as to develope integrative distributed hydrological model.And it also can combine other major system models to built Model Library Integrated System.The combination of hydrology,climate,society,economy,ecology,environment etc,can form a new-fashioned model system,which can meet the simulated needs well,and reflect the actual situation more veritably and accurately.
