4) scour and silting evolution
冲淤演变
1.
In this paper,the scour and silting evolution regularities of the Guanhe River main channel and outlet channel are obained by analyzing the observed hydrographic and topographic data in recent 20 years.
通过对近20 a实测水文地形资料的深入分析,得到了灌河干流河道及出口水道的冲淤演变规律:干流河道在盐东控制闸建闸前,以响水为界上段冲刷下段淤积,建闸后,从多年平均来看上段明显淤积下段冲刷;近10 a来,陈家港以下的干流河道弯道凹岸处均为深槽逼岸的冲刷区,且处在持续稳定冲刷状态;自20世纪80年代以来,灌河口外岸滩冲刷强度减弱,近10 a来,河口外冲淤近于平衡状态。
