摘要
研究三峡水库中长期来水水量平衡模型。在利用中长期降雨预报的基础上,通过对2参数水量平衡模型进行参数率定并采用实际过程进行检验,提出了适合三峡水库的水量平衡模拟模型。结果显示2参数水量平衡模型模拟的三峡水库中长期径流过程与实测径流过程吻合度较高,峰值对应关系也较好,取得较高模拟精度。
Based on middle-term and long-term rain-fall forecasting, a comprehensive forecast method of three gorges reservoir using water balance model is presented in this paper. Then an experiment is made on the method and the forecasting result is checked. The results show that runoff observed and simulated has high superposition, peaks match well, and the result has a high simulating precision. The water halance model has a good prediction effect.
