摘要
在对禹潼河段近期冲淤特点深入分析后指出:该河段近期河道淤积量尤其是主槽淤积量明显增加,滩槽高差减小,河槽排洪能力下降,已建工程防洪标准降低,工程临背差加大,险情频繁发生,防洪形势严峻。
Based on field investigation and large quantity of measured data, a deepgoing analysis on the recent sediment sluicing characteristics of the Yellow River from Yumenkou to Tongguan is conducted. The results indicate that in recent years, the sedimentation in the river channel, especially the main channel, is evidently increased, leading to reduction of flooding bed height difference and flood discharging capability, flood control standard of existing projects lowered, risks frequently occurred and serious flood control situation.
