  1. Abstract : digital basinis made from digital elevation model considering spatial variability within a catchment. on the basis of digital basin, the digital approach to describing hydrological processes within a catchment is investigated. digital hydrological model is regarded as a modern physically - based modeling technique that includes a large amount of information. the case study on the shiguanhe catchment in the huaihe river basin, intensified observation field of gewex asian monsoon experiment project, has shown that the digital mode lperforms very well not only in simulating runoff processes at any specific site, but also in simulating spatial distribution and temporal variation of hydrological elements and state variable ( especially soil moisture ), if compared with traditional hydrological models. that provides solid foundation for full use of now available observation in formation and in - depth mining of hydrological data
