Abstract: The paper summarizes the hydraulic characteristics of two types of drop structure, termed tangential-inlet vortex-flow drop structure and two-ramp vortex-flow drop structure, for diverting flows from near-surface storm-sewer systems to underground storage tunnels. A series of physical model studies were conducted to arrive at the final configurations. The tangential-inlet drop structure in general requires an open-cut construction, while the two-ramp drop structure can be constructed by tunneling technique, which can be more suitable in urban areas where open-cut construction can be expensive and undesirable.
