The calculation of normal water depth could be converted into a nonlinear constrained optimization problem,which could be solved by a new pattern searching algorithm.Through the application examples and comparing the simulation results with the referent results,it is shown that the new pattern searching algorithm is much more applicable,precise and simple than the traditional methods for the calculation of normal water depth.At the same time,the correctness and validity of the new method is demonstrated,which could provide a new tool for obtaining the normal water depth of circular drainage pipe line.
