Mobile Discharge Measurement,ddition, the thin-plate Venturi flume is presented that is proposed for larger channels or rectangular sewers of width up to 3 m, with an access by a standard manhole. Mobile discharge measurement with overflow structures is not recommended, because the mounting precision, the security and accuracy are demonstrated to be unsatisfactory.

BRIEF

Backwater Curves,ion step is needed. The procedure is detailed by describing the computational scheme and explained with examples. Apart from the circular section, the egg-shaped and the horseshoe sections as well as the rectangular section are also considered. Finally, the effect of the non-hydrostatic pressure distribution on the discharge is discussed.

Side Channel,ecessary..Finally, the spatial flow features of side channels are described by including the rotational flow component. Orders of magnitude for the lateral pile up of flow along the channel walls are given, and the effects of so-called tornado vortices are described.

EXPEL

Basic Equations,ed..Lastly, the energy principle is presented and a few simple conclusions with regard to the energy flux are derived. The discussion of results refers, in particular, to the similarity between the hydraulic and the hydrodynamic approaches.

Losses in Flow,..The . are ascertained for a number of conduit geometries and channel configurations and optimal dimensional ratios are indicated. Finally, flows in pressure conduits and free-surface channels are compared.
