An New Approximate Formula for Contracted Depth in Quadratic Parabola Shaped Channels

Abstract:

On the basis of summarizing the predecessors' research, based on the contracted depth basic equation mathematical transformation of quadratic parabola shaped sections, the interrelation between dimensionless contracted depth and the dimensionless parameter were analyzed, we obtain the approximate formula for contracted depth in Quadratic parabola shaped channels, it is simpler and accurate, Its maximum relative error are less than 0.12% in the utility range.
