摘要
本文根据暴雨径流悬移质浓度变化特点，采用最小二乘法对暴雨期间污染源各监测数据进行回归分析处理，并考虑到表面风力，建立了湖泊水库暴雨径流是移质模型。对滇池湖泊某次暴雨过程的悬移质泥沙进行了模拟计算，得到了该次暴雨径流的泥沙淤积等值线分布图。计算结果表明，该模型应用于滇池湖泊是成功的，具有较强的通用性。
According to the characteristics of suspended sediment distribution of storm runoff, the regress fraction analysis for the contamination monitor data during the rainstorm is made by the use of least square method. Then, with the consideration of wind force, a storm runoff suspended sediment model in lake and rese-rvoirs is built. Applying the model to Lake Dianchi, the authors carry out the simulation of suspended sediment distribution of the rainstorm,and obtain the isolate map of sediment deposition of a certain rain-storm. The results show that the model is successful in Lake Dianchi and can also be generally applied.
