    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.

    CONTRIBUTION TO THE STUDY OF THE SEMI THEORETICAL APPROACH OF THE HYDRAULIC JUMP IN A RECTANGULAR CHANNEL OF COMPOUND SECTION WITH ROUGH MAJOR BED
    (university of el oued/جامعة الوادي, 2021-01-01) Lacheheb, S; Ghomri, A.; Kateb1, S
    The purpose of this study is interested in the semi-theoretical analysis of the hydraulic jump evolving in a rectangular straight compound channel with rough major bed. A functional relationship, non-dimensional terms, linking together the different characteristics of the projection, is obtained.

    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.

    EXPERIMENTAL STUDY OF THE HYDRAULIC JUMP IN A HYDRAULIC JUMP IN A SLOPED RECTANGULAR CHANNEL
    (University of Eloued جامعة الوادي, 2018-01-01) Kateb, S.; Ghomri, A.; Debabeche, M.
    The hydraulic jump in a sloped rectangular channel is theoretically and experimentally examined. The study aims to determine the effect of the channel’s slope on the sequent depth ratio of the jump. A theoretical relation is proposed for the inflow Froude number as function of the sequent depth ratio and the channel slope. An experimental analysis is also proposed to find a better formulation of the obtained relation. For this motive, five positive slopes are tested. The relations obtained are recommended for designing irrigation ditches.

    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.
