    CONTRIBUTION TO THE EXPERIMENTAL STUDY OF THE HYDRAULIC JUMP IN TRAPEZOIDAL CHANNEL WITH POSITIVE SLOPE
    (University of Eloued جامعة الوادي, 2018-01-01) Ghomri, A.; Riguet, F.; Khechana, S.
    The purpose of this study is to study experimentally the hydraulic jump evolving in a symmetric trapezoidal channel with a positive slope, requires the use of an experimental protocol, and to find experimental relations linking the characteristics of the formed projection. The experimental study investigated the variation of the relative height S = s / h1 of the threshold as a function of the Froude F1 number of the incident flow, for five distinct values of the slope of the channel.

    Effect For A Single Roughness E=5,63mm Of Experimental To Study Hydraulic Jump Profile In A Channel In U A Rough Bottom
    (University of Eloued جامعة الوادي, 2013-01-01) Ghomri, A.; Riguet, F.; Debabeche, M.
    This study aims to study the hydraulic jump controlled by threshold, moving in a channel profile 'U' bottomed rough for a single roughness E=5,63mm. Functional relations in dimensionless terms, linking the different characteristics of the projection, showing the effect of roughness of the bottom of the channel are obtained. The hydraulic jump is the primary means used by hydraulic structures to dissipate energy. This hydraulic jump is formed at the sharp transition from a supercritical flow a stream flow.

    Stady of the SEMI- Theoretical Relation of the Hydraulic JuMP Evolving in An U-SHaped Channel, With Rough Bed
    (University of Eloued جامعة الوادي, 2009-07-01) Ghomri, A.; Debabeche, M.; Riguet, F.
    This study has for objective to study the theoretical relation of the hydraulic jump by sill, evolving in an U-shaped channel, with a rough bed. Functional relations, in non-dimensional form, relating the jump characteristics, seeming the effect of the bed's roughness, are obtained. A comparative study with the hydraulic jump in U-shaped channel, with smooth bed is proposed.
