It has realistic significance to research on using working gate with submergeddischarge to measure water in canal for slab irrigation district.
对于平原灌区，研究利用以淹没出流为主的工作闸门进行渠道量水具有现实意义。

In the case of small opening, submergeddischarge, and water-stop rubber damage, the interaction between water and gate may cause vibration which result in gate damage.
在小开度、淹没出流情况下，如果止水橡胶损坏，水和闸门的相互作用将导致闸门产生破坏性的振动。

Changes of the water level on submerged and non-submerged condition are similar on the whole, and variation amplitude of water lever increases with the increasing discharge in both situation.
