Résumé

The storm water drainage network is generally calculated based on the Manning equation, where the slope, roughness of the pipe wall, and flow are known, while conversely the velocity, diameter, hydraulic radius are unknown characteristics, although they are very important for the work of the hydraulic engineer who needs to find their values, even the students taking coursework relating to Waste-Water Engineering. The computation of these parameters in partially full pipes and based on the Manning equation is implicit and needs to be computed through iterative and laborious methods. In this paper a new simple and easy method will be presented based on a reference pipe with known characteristics (Known Reference Pipe Method: KRPM), as well as the effect of the up-pipe parameters on the down-pipes according to each case that is possible through the watershed drainage system arrangement, for both full and partially filled circular pipes.
