Cette communication présente une méthode graphique simple,rapide et compléte et une méthodologie qui permettent de déterminer les caractéristiques principales du ressaut hydraulique, paramétres nécessaires pour dimensionner le bassin de dissipation classique.
La méthode graphique prend en considération les contraintes imposées par la réalité du terrain ou la pratique, comme celle liées à la topographie du site, la préservation de l’equilibre de l’environnement ainsi que le côté technico-économique.
Cette méthodologie consiste à imposer la perte de charge dissipée par le ressaut hydraulique comme hypothèse (dimensionnement libre) pour déterminer tout les autres paramètres du bassin de dissipation classique.
On peut imposer la perte de charge DH dissipée par le ressaut hydraulique, égale à une valeur choisie ou égale à un certain pourcentage de la charge amont totale crée par le barrage.
A l’aide du paramètre adimensionnel DH+ =(DH/k),(k :profondeur critique), la représentation graphique élaborée permet de déterminer les autres paramètres, dont le produit par k donnent les caractéristiques principales du ressaut hydraulique, paramètres nécessaires pour le dimensionnement du bassin de dissipation classique.
Cette solution est souvent optée pour dimensionner les bassins de dissipations des petits barrages en béton ou pour les retenues collinaires.
La vérification des résultats obtenus et leur comparaison à des données pratiques confirment la validité et la fiabilité de la méthode graphique élaborée.

This communication presents a graphical method simple, fast and complete and a methodology for determining the key features of the hydraulic jump, parameters necessary to size the basin of classical dissipation.The graphic method takes into account the constraints imposed by the reality of the field or practice, such as that related to the topography of the site, the preservation of the balance of the environment as well as the technical and economic side.This methodology is to impose loss of load dissipated by the hydraulic jump as a hypothesis (free design) to determine all the other parameters of classical dissipation basin.Can impose the loss of charge DH dissipated by the jump hydraulic, equal to a predetermined value or equal to a certain percentage of the total upstream load created by the dam.Using the adimensional parameter DH + = (DH/k),(k:profondeur critique), elaborate graphic representation to determine other parameters, including the product by k gives the main features of the hydraulic jump, necessary parameters for sizing of classical dissipation basin.This solution is often preferred for sizing the basins of small dams in concrete or for hilly deductions dissipation.The verification of the results and their comparison to practical data confirm the validity and reliability of the developed graphical method.

This paper presents a simple graphics, fast and compléte and methodology for determining the main characteristics of hydraulic jump parameters necessary to size the classic stilling basin.
The graphic method takes into account the constraints imposed by the reality on the ground or practice, such as that related to the topography of the site, preserving the balance of the environment as well as the technical and economic side.
This methodology is to impose the loss of load dissipated by the hydraulic jump assumption (free sizing) to determine all the other parameters of conventional stilling basin.
DH pressure drop can be imposed dissipated by the hydraulic jump, equal to a selected value or equal to a certain percentage of the total upstream load created by the dam.
At the Using the dimensionless DH + = parameter (DH / k) (k: critical depth), the elaborate graph to determine the other parameters, the proceeds by k gives the main characteristics of hydraulic jump parameters necessary for the design of the basin Classic dissipation.
This solution is often opted to size pools dissipation small concrete dams or hill dams.
Verification of results and their comparison with practical data confirm the validity and reliability of the graphic method developed.
