Efficient Equations for Circular Partly-Full Pipe Hydraulics
Hydraulic calculations performance becomes a very significant factor when large urban drainage systems are modeled under dynamic conditions for many hours of simulation duration. These systems typically contain many thousands of partly full circular pipes of different sizes and the hydraulic calculations of normal depth, critical depth and critical slope are involved in every pipe at every time step. This paper presents a method in which the theoretically exact circular pipe equations are represented by very simple explicit polynomial equations. These explicit equations are shown to be fast and accurate. Significant performance improvement is achieved by replacing the iterative method with the explicit equations.
