赵口引黄灌区有众多河流沟道是排灌合一的运行方式,即既行洪除涝又输(蓄)水灌溉,分析这种利用方式的发展由来,在运行管理中需注意以排水为主兼灌溉,灌溉时河沟内水位一般不宜高于除涝水位。在干旱缺水的平原区利用河道排灌合一与灌排分设相比优越性显著,在适宜的地区可借鉴使用。
There are many river channels in the mouth of the Yellow River Diversion Project in Zhao mouth, which is a combination of drainage and irrigation. That is to say, both flood and waterlogging (water storage) and water (irrigation) irrigation are analyzed. The development of this utilization mode is analyzed. In operation and management, Main and irrigation, irrigation in the river ditch generally not higher than the water level in addition to waterlogging. In the arid and dry plain area, the use of riverbed irrigation and drainage and irrigation and drainage is superior compared with irrigation and drainage points, and can be used for reference in suitable areas.
