In addition, a viaduct that was built to solve Guangzhou's transportation problem covered the skyline of the river. At present, the flood control and drainage capacities of the DongHaoChong basin are such that it can withstand rainfall for a recurrence period of only one year. DongHaoChong ...
full filling discharge capacity determined with the Manning's Equation for uniform flow: √ Uav = R2h/3 S/n (1) where Uav is the average velocity (m/s), Rh is the hydraulic radius (m), S is the slope of the pipe (m/m) and n is the Manning's roughness coefficient (s/m1/3)....
