In this work we have presented aims to study the calculation backwater curves for gradually varied flow with a free surface in open channels of non-prismatic profile with the use of mathematical methods, which allow drawing the line water to various sections, and specifying the general appearance of the different forms of the water surface. The proposal has many advantages and disadvantages, role being the knowledge of the construction works on the water level upstream the passage of a flood, to assess and reduce the risk of flooding. After the definition of modeling resolution, we need to apply the characteristics of non-prismatic channels. This project presents a study of mathematical calculation (Method Bakhmeteff) with different sections chosen because they are shorter and less complicated than other methods.

Abstract
In this work we have presented aims to study the calculation backwater curves for gradually varied flow with a free surface in open channels of non-prismatic profile with the use of mathematical methods, which allow drawing the line water to various sections, and specifying the general appearance of the different forms of the water surface. The proposal has many advantages and disadvantages, role being the knowledge of the construction works on the water level upstream the passage of a flood, to assess and reduce the risk of flooding. After the definition of modeling resolution, we need to apply the characteristics of non-prismatic channels. This project presents a study of mathematical calculation (Method Bakhmeteff) with different sections chosen because they are shorter and less complicated than other methods.

Abstract: (french)
L'objectif du travail que nous avons présenté est l'étude du calcul les courbes de remous pour les écoulements graduellement variés à surface libre dans les canaux découverts de profil non prismatique, avec l'utilisation des méthodes mathématiques ,qui permettent de tracer la ligne d'eau à de diverses sections, et de préciser l'aspect général des différentes formes de la surface d'eau. La proposition a de nombreux avantages et inconvénients, le rôle étant la connaissance de la construction des ouvrages sur le niveau de l'eau en amont au passage d'une crue, pour évaluer et éviter les risques d'inondations. Après la définition du modelé de résolution, on nécessite d'appliquer les caractéristiques des canaux non prismatiques. Ce projet présente une étude de calcul mathématique (Méthode de Bakhmeteff) avec de différentes sections choisies, puisqu'elles sont moins longues, et moins compliquées que les autres méthodes.
Author Keywords: surface d'eau, modelé, écoulements, risques d'inondations, sections.
