Dynamic Wave Simulation of Unsteady Open Channel and Surcharge Flows in Sewer Networks (saint-Venant Equations, Four-Point Implicit Finite Difference, Storm Sewer Drainage, Urban Hydrology)

Sewers are traditionally designed to operate under open-channel flow conditions. However, it is not uncommon that under high flows some or all of the pipes in a sewer network may change from open-channel flow to surcharge flow. For surcharge flow in a sewer there exist two techniques of mathematical simulation. One is the standard technique which separates surcharge flow from open-channel flow and represents them mathematically by using two different sets of equations. The other is the Preissmann slot technique which simulates surcharge flow as open-channel flow using a hypothetical narrow open piezometric slot at the sewer crown. The flow is described mathematically using the unsteady open-channel Saint-Venant equations. In either case, a reliable simulation model is required to represent the flow process properly.
