Pipe Culverts – Throttling Pipes – Inverted Siphons
Abstract Culverts are characterized hydraulically by various flow conditions. They are discussed first and then analyzed with a generalized diagram to present a simple design method. The so-called simple culvert is also considered, and the computational approach is compared with model tests. Throttling pipes perform correctly only under pressurized flow. The principle of pipe filling is described and two conditions of flow are highlighted. Examples illustrate the computational procedure. Inverted siphons can be arranged in various ways thereby complicating a general design method. The most important features regarding the intake structure, the throttling pipe and the outlet structure are discussed. The design is also illustrated with a typical example. Thus, the three structures in which either free surface or pressurized flow may appear are described with a comparatively simple hydraulic approach.
