| description | <p>This study aims to investigate the threshold-controlled hydraulic jump, moving in channel profile 'U' fully rough for a single roughness value e = 7,14 mm. Functional relations in dimensionless terms, linking the different characteristics of the jump, showing the effect of bottom friction channel, are obtained as: <strong>y<sub>2</sub>= (-14,19y<sub>1</sub> + 6, 42) Q*;</strong> <strong>y<sub>2</sub>= 1,13y<sub>1</sub><sup>0,65 </sup>exp [0,95y<sub>1</sub><sup>0,61</sup>.s/h<sub>1</sub></strong>] .</p><p>The method is as follows: we vary the flow volume by manipulating the valve and their measurements are read directly on the meter display éctronique. Supply channel is by means of a pump flow up 40 l / s. The flume was designed in the laboratory 'LARHYSS, University of Biskra.</p> |
