三水源新安江模型在陕西营流域的应用
首发时间:2011-12-31
摘要:本文通过不同方式分析论证了陕西营流域的产流方式,在判定其产流机制为蓄满产流且符合三水新安江模型适用条件的前提下,将模型应用于陕西营流域。经过参数率定和模型检验,确定其日模型和次洪模型预报方案达到了甲等或乙等。根据《水文情报预报规范》,三水源新安江模型在陕西营流域应用良好,可进行作业预报。

Application of Three-source Xin'anjiang Model to Shan xiying Catchment
Abstract:In this paper, it demonstrates the mechanism of runoff yield of Shanxiying catchment with different methods. When it is concluded that the mechanism of runoff is the one under saturated storage and meet the conditions of application for Xin'anjiang model, the three-source Xin'anjiang Model run to Shan xiying Catchment. Through Parameter Optimization and Back-checking for model, it is defined that the daily-discharge model and the once-discharge model reach the standard of A or B level. According to The Code of Hydrologic Information Forecast (SL250-2000), the model has good applicability in the catchment and it can be used for forecasting.
Keywords: Xin'anjiang Model Shan xiying mechanism of runoff Parameter Optimization
