[0002] In literature, cross-sectional flow rate refers to the amount of water flowing through a water section per unit time, usually represented by Q, with units of cubic meters per second. The flow velocity at each point on the river section is different. The flow velocity at the upper part of the section is large, while the flow velocity at the river bottom and river bank is small due to friction resistance. Therefore, the amount of water flowing through the water section per second is an irregular curved surface. When detecting the cross-sectional flow rate of the river, a special flow detection device is required.
