摘要
云峰水库入库洪水预报方案为1993年编制的上下游流量相关和降雨径流相关方案,方案精度大多为乙级,且没有包含1993年以后的大洪水信息,难以满足实际防汛工作要求,急需完善。本文针对鸭绿江流域洪水特点及下垫面条件,采用线性动态系统预报方法建立云峰水库入库洪水预报系统,进一步完善鸭绿江流域洪水预报体系。
The forecast scheme of reservoir inflow flood for Yunfeng reservoir, compiled in 1993, is the correlation scheme between the upstream and downstream flow and the rainfall-runoff. Because of the B class of the scheme precision and the shortage of the big flood data after 1993, the scheme cannot satisfy the request of practical flood control work. According to the flood characteristics and underlying surface conditions, the forecast scheme for reservoir inflow flood is built by using the linear dynamic system forecast scheme for Yunfeng reservoir to perfect the flood forecast system of Yalujiang river basin.
