水库汛限水位动态控制的实现途径

水库汛限水位动态控制是洪水资源利用的主要方式之一,提高水库洪水预报精度和延长有效预见期是实现水库汛限水位动态控制的关键所在。针对水库实时防洪调度的特点和流程,概述了新一代天气雷达、气象卫星及相关应用系统的技术进展,评价了这一技术进展在水库实时防洪调度中的重要作用,据此提出了综合应用新技术改进水库洪水预报、洪水量级判断和蓄水时机选择的技术途径。在此基础上,以海河流域潘家口水库为例,综合论证了水库汛限水位的动态控制范围,提出了汛期蓄水的控制策略与调控方法。

Available approach to controlling dynamically the limited level of reservoirs during the flood season

Controlling dynamically the limited level of reserwirs during the flood season is one of the main methods of utilization flood re}urces.Improving the flood forecast accuracy and period is the key to controlling dynamically the limited level of reserwirs during the flood season.Firstly,the paper illustrates the advances of the new generation of the weather radar,the meteorological satellite and the related application systems,and the roles of the new technology in the real time operation of reserwirs are discussed.Then,the methodology and the technical framework of improving flood forecast and optimizing the impounding scheme of the reservoirs by using synthetically the new technology are proposed.Based on this,the dynamic control range of the limited level of reservoir is analyzed synthetically to use flood safely wrath the Panjiakou Reserwir in the Haihe River Basin as an example,and the impounding strategy and regulating method of reservoir during the flood sewn are provided.
