Analytical Solution of Water Depth in Parabolic-Shaped Channel with Contracted Section

WEN Hui,LI Feng-ling(Department of architecture Maoming University,Guangdong Maoming 525000,China)  
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.
