摘要
黄河小浪底水库运用后,可有效控制黄河下游河道流量,基本解决了山东黄河的防凌问题。但受小流量封河、跨流域调水和突发事件等因素的影响,山东黄河防凌又出现了新的问题。2001年小浪底水库投入防洪调度运行以来,对黄河山东段的河道变化情况及气温、水情、凌情等因素进行了分析,提出了做好防凌工作的建议。
After the operation of Xiaolangdi Reservoir, fiver flow in the down stream of the Yellow River is effectively controlled, which ice jam in the Shandong section of the Yellow River is mostly prevented. However, new problems with ice jam control in the Shandong section comes out because of fiver frozen due to small flows, across-basin water diversion and occurring of emergencies. On the basis of analysis of changes of fiver course conditions, temperature, water and ice-jam conditions in the Shandong section after the operation of Xiaolangdi Reservoir in 2001, suggestions for bettering work of ice jam control is proposed.
