A simple and efficient method for flow routing, combining the kinematic wave equation with a statistical procedure, is introduced. It accounts for the nonlinearity and the dispersion of the flood wave propagation phenomenon and for lateral flow. The method is flexible, because it can be used to simulate a variety of flow variables, for example, water stage or discharge. Its calibration is based on historical records at both ends of the reach, and does not require geometric cross‐section or longitudinal data. An application to the White Nile in Sudan demonstrates the practicality and accuracy of the method.
