  submerged weir
Since a submerged weir (3) located in a lateral distributary does not have a significant effect on the redistribution of discharges, its placement to increase the discharge in the main distributary is not rational.
      
The placement of a submerged weir (2) in the main distributary can be recommended for "reviving" a lateral distributary (increase of the discharge in it).

In a broad plain river,sometimes the differences of water levels and discharges between the drainage and the flood diversion are large.The structure layout in which a sluice is located only in main channel and two spillways are located in flood plains is more economic than that where a single sluice is constructed along the river width.The experiments were carried out on the discharge capactity of the two structure layouts and on the velocity profiles of upstream and downstream river of the pojects.The determination of the fall of sluice,the calculation of the approaching velocities in relation to every part of the structures and the influence of the height of end sill of stilling pool on the discharging calculation of submerged weir were also investigated.

在平原河道,当排涝水位和分洪水位、排涝流量和分洪流量相差悬殊,又有蓄水灌溉要求,而河道本身宽阔时,采用主河道布置节制闸、两侧滩地布置溢洪道的枢纽布置形式比全河宽采用节制闸的单一布置形式经济。结合工程,对这两种枢纽布置对应的上下游流速分布、泄流能力等进了对比试验。对平原水闸过闸落差的确定、对闸桥枢纽各泄流部分对应的行近流速取值以及消力池尾槛高度对淹没堰流流量计算影响等问题进行了试验研究。
