چکیده:

Flow pattern in the mild meandering rivers is completely different from that of strongly curved meanders. The results of this experimental study showed that in mild meander rivers, the maximum velocity is about 1.3 times the mean flow velocity. The maximum dimensionless radial and vertical velocity components was found to be about 8% of the mean velocity. Also, the maximum values of MKE occured at the locations of the maximum streamwise velocity whereas high values of TKE occured at the inner bank of the region downstream of the bend apex. The above results can be used to find meandering patterns in river training works
