Debabeche %J Journal of Fundamental and Applied Sciences %D 2012 %I El Oued University %X This study aims to study the hydraulic jump controlled by threshold, moving in a channel profile 'U' bottomed rough for a single roughness ŠĆ = 9,11mm. 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. %K Hydraulic jump %K channal-shaped in U %K stilling basin %K channel bottom rough. %U http://www.jfas.info/index.php/JFAS/article/view/75/pdf
