The hydrological model,which is a technology developed since 1960s,is a kind of mathematical methods for simulating the hydrological process in the watershed.The the simulation of hydrological process can be divided into two sub-hydrological process,one is the runoff generation simulation and the other is the routing of flow.In the lumped hydrological model the hydrological variable and parameter are assumed as uniform in the whole basin. Due to the Geography Information System technology the distributed hydrological model,which can dea with variety of hydrological variable and hydrological parameter,had got more attention and development. In addition the spatial information,needed by the distributed hydrological model,can be got more easily because of the development of the Remote Sensing technology.
