Abstract


Digital Basin generating system is digital hydrographic an important part of the study , high-quality water generation model can greatly improve the overall hydrological models in the course of the validity and accuracy , so as to improve the accuracy of regional hydrological modeling provides an important guaranteed. This paper reviews the digital elevation based generation system Digital Basin progress of the study , many hydrological model for the current generation of watershed water shortage that exists , we propose a suitable Digital Basin hydrology studies generating method , and so establishment of the corresponding system . This paper analyzes the generation Digital Basin general approach taken , and for the actual situation to take a \situation in which to generate the actual river channel and to achieve a good fitting effect , but also more in line with the actual situation of convergence . Meanwhile, the system of many hydrological model for the current generation of sub basin analysis problems of weak , combined with professional knowledge and practical needs of the division increased sub-basin , control and analysis functions, and on this basis, the initial realization of practical applications to meet digital drainage network generation system .
