suspended sediment effects on submerged hydraulic jump characteristics
abstract in this study, the effect of suspended load transport on the characteristics of submerged hydraulic jump (shj) in a rectangular channel was investigated experimentally. sediment concentration and jet froude numbers in the range of 0.424%-16.15% and 1.93-4.96, respectively, were considered. tow grain size 0.15 and 0.03 mm were used in the experiments. characteristics of submerged hydrau...
متن کاملCharacteristics of Hydraulic Jump
The effect of an abruptly expanding channel on the main characteristics of hydraulic jump is considered experimentally. The present study was made for supercritical flow of Froude number varying between 2 to 9 and approach to expanded channel width ratios 0.4, 0.5, 0.6 and 0.8. Physical explanations of the variation of these characteristics under varying flow conditions are discussed based on t...
متن کاملExperimental Study of the Effect of Gabion Structure on the Energy Dissipation of Submerged Hydraulic Jump Downstream of Ogee Spillway
In the last decade, the use of gabion structures in hydraulic engineering for stabilizing the structure due to its high density and weight has become widespread. Also, the material's roughness and porosity cause it to be used in energy dissipation and drainage projects. This study evaluates the relative energy dissipation of gabion structures downstream of the ogee spillway in the conditions of...
متن کاملevaluate and develop new relationships to estimate submerged hydraulic jump characteristics
in this research, in order to develop new relationships with reasonable accuracy for estimation of the submerged hydraulic jump characteristics, a study has been conducted experimentally. experiments have been done in a rectangular channel with a length of 9 m, a width of 0.5 m and a depth of 0.45 m. froude numbers in these tests range from 3.5 to 11.5 and between submergence ratios of 0.1 t...
متن کاملHydraulic Experiments for Determination of In-situ Hydraulic Conductivity of Submerged Sediments
A new type of in-situ hydraulic permeameter was developed to determine vertical hydraulic conductivity (VHC) of saturated sediments from hydraulic experiments using Darcy's law. The system allows water to move upward through the porous media filled in the permeameter chamber driven into sediments at water-sediment interface. Darcy flux and hydraulic gradient can be measured using the system, an...
