Summary

The method of characteristics is applied to solve the unsteady partially filled pipe flow equations applying to the flow in building drainage systems. Wave attenuation, together with the propagation of steep fronted waves and the transport of discrete solids, is modelled and comparisons drawn with experimental investigations undertaken with representative pipe size and flow loading values.
