Abstract
A practical runoff simulation method of a surcharged flow in the sewer pipe systems is presented. First, a pressure-relaxation effect, which is caused by the storage of runoff water in both the manholes and the lateral pipes and reduces considerably the pressure wave celerity of the surcharged flow, is analyzed theoretically. Second, a practical simulation method of the flow, in which the large computational time interval can be used compared with the traditional simulation methods, is devised by making use of the relaxation effect. Finally, the validity of the method is examined by the laboratory experiment and the numerical simulation.
