流速约60~70 cm/s，此时水流紊动作用更加剧烈，底部淤泥被成片掀

The flow velocity is about 60~70 cm/s. At this time, the turbulent action of the water flow is more intense, the bottom silt is lifted in pieces, and the water flow becomes turbid in a short time, especially when a certain part of the silt is lifted, the remaining sludge in this part is Get in motion sharply. When the flow velocity exceeds 70cm/s, the state of the water current movement is similar to the "general movement" at this time, and it is observed that there is a large amount of sediment suspended in the water body at this time.

The flow rate is about 60 to 70 cm/s, at this time the water flow movement is more intense, the bottom silt is lifted in pieces, the water flow in a relatively short period of time is cloudy state, especially when a local silt is lifted, the remaining silt in that part will move sharply. Flow rate of more than 70cm/s, at this time the state of water movement is similar to "general movement", observation found that at this time there is a large amount of sediment suspended in the water body.

The flow velocity is about 60 ~ 70 cm / s. at this time, the turbulence of the flow is more severe, the bottom sludge is lifted up in pieces, and the water flow is turbid in a short time, especially when a part of the silt is lifted up, the remaining sludge will move rapidly. When the flow velocity exceeds 70cm / s, the current movement state is similar to the "general movement". It is observed that there is a large amount of suspended sediment in the water body at this time.<br>
