摘要
Partially filled pipeflows were encountered in drainage systems belonging to a family of unsteady flow problems. Basic equations were developed and numerically solved also by the characteristic different methods with time-line interpolation scheme. The boundary conditions for the inflow, outflow, moving hydraulic jump and junctions were developed experimentally and numerically. Full scale model experiments were carried out. It is consequently clarified that numerical model is capable of predicting flow characteristics in realistic drainage networks.
