Abstract: The method of characteristics (MOC) with spline polynomials for interpolations was investigated for numerical water hammer analysis. The overall accuracy is significantly improved compared to the MOC with linear interpolations or to second-order explicit finite difference techniques. A new error analysis quantifies numerical attenuation and dispersion in a systematic way.
