Though the water levels cross one section are almost equal , the velocities differ greatly . at the some cross - section , the velocity in the in the quirk may be double as that on the floodplain . the water surface will rise hi the southern branch because of the improper diffluence ratio , if using the designed diffluence col 淮河入海水道河口段水位值横向分布相差无几,而流速的横向变化较大,泓滩平均流速差最大可达一倍以上,在现有的分流口设计条件下,若按设计的南北汊分流比,南分流口有壅水现象发生,如果南汊分流增大到800m ~ 3 / s左右时,则水流较为通畅。
