# 新安江模型在鄱阳湖区水量计算中的应用研究Calculation of Water Quantity in the Poyang Lake Area Using Xin’anjiang Model

Abstract: Poyang Lake area is flat and has interlaced river network, so the water quantity of intervening basin area can not be obtained by traditional hydrological observation methods and only through indirect method, such as water balance method. The Xin’anjiang model with three runoff components was used to discuss the rules of runoff generation and confluence in lake area. Taking the advantage of the Xin’anjiang model as a distributed model, the runoff yielding generation area was divided into many sections on the basis of land and lake surface; By carrying out the calculation of runoff generation and overland flow routing in and obtaining the outflow of each section, and then through the calculation of the river network routing, the flow process of the outlet section of the whole river basin was obtained by accumulation. The water quantity calculated by the Xin’anjiang model was analyzed and the results show that the overall outcome is reasonable.
