Abstract
Triangular ditch irrigation may be used to raise the downstream water surface. In this paper hydraulic jump in a sloped triangular channel of 90° central angle has been studied and analyzed using field experiments. The paper aims to determinethe effect of the triangular channel’s bed slope on the hydraulic jump characteristics such as sequent depth ratio, relative jump height, relative energy loss, and the relative jump length. For this motive, wide range of bed slopes, nine positive slopes were tested. The obtained results were represented in dimensionless curves and empirical models using Buckingham’s π-Theorem. The developed curves and empirical computational models
were used to estimate the different hydraulic jump characteristics for different initial Froude number and triangular channel bed slope. Also, the obtained results were compared with the pervious results of horizontal triangular channel layout.
