| Abstract: | After analysing the watershed landform with the method of Geography Information System(GIS), the movement of a water particle can be conveniently traced in the process of watershed flow concentration. Its flow concentration time, which is from the starting point to the watershed outlet, is connected with the length and gradient along the flow pathway. According to the method, the flow concentration time of a water particle can be computed, which makes it possible that creates the model of equivalent flow duration con-tour aided by computer. The simulation method is proved effective by examing Huangshan runoff experiment basin. |
