Abstract: The increasingly frequent use of detention basins in drainage networksrequires adequate care in choosing the regulation device for the discharges[1].Indeed,the use of orifices wide enough to prevent the danger ofocclusion does not allow the lamination effect to be fully exploited.Onthe other hand,a device which is too limited or which has mobile partspresents an often unacceptable risk of shortcomings.At present,numerousdevices are used:these exploit the transformation of part of the waterpotential energy into rotating kinetic energy or use the braking action onthe main current by an additional tangential control current (vortexamplifiers).These systeme,originating from the field of fluidics[2][3],have had many applications in hydraulic field,although in their useproblems may occur.In particular when the risk of occlusion is greater as,for example,in urban drainage networks.With reference to this field ofapplication,the distribution of the available head on a set of gates,asshown in fig.1,does not seem to have been widely used.
