Abstract: Through the identical deformation of the basic equation about the contracted water depth of parabolic shaped channel, we can obtain a non dimensional formula, which is a typical quartic equation with one unknown . According to this equation ' s solution, we can also obtain an analytical expression for calculating water depth about the contracted water depth of parabolic shaped channel, it provides one kind of new solution for calculating the water depth about the contracted section of parabolic shaped channel. The analytical formula is short cut and its result is correct, and can be widely used. It also overcomes the shortage of consulting graph list and trial computation methods widely used in the past time.
