Transformation of Hydrological Modeling Techniques in the Digital Era

In this paper, the course of development of hydrological modeling techniques, from the atomic age to the digital era in which high tech revolution lies currently,is remarked from the viewpoint of methodology of science and philosophy. A brief review is made on the origin of digital hydrology. And a discussion is made on connotation, framework, development and scientific significance of digital hydrological model. The position of digital hydrology in digital earth is investigated. It is seen from analyses that digital information technology will transform the means of scientific research in hydrology, and make it possible to improve hydrological model significantly;and that digital hydrology plays an important part in digital earth, and is worth further research.
