Hydraulic jump is a rapidly varied flow in open channels which performs an effective role in dissipation of the kinetic energy of flow at downstream of water structures. In the present study the characteristics of hydraulic jump, including sequent depth, energy dissipation, bed shear stress and velocity profiles at different sections, on rough bed with discontinuous roughness elements of lozenge ‫آراﯾﺶ‬ ‫و‬ ‫ﺗﺮاﮐﻢ‬ ‫ﺑﺎ‬ ‫زﺑﺮ‬ ‫ﺑﺴﺘﺮ‬ ‫روي‬ ‫ﺑﺮ‬ ‫ﻫﯿﺪروﻟﯿﮑﯽ‬ ‫ﭘﺮش‬ ‫ﻣﺸﺨﺼﺎت‬ ‫ﺑﺮرﺳﯽ‬ ‫ﻫﺎي‬ ... 15 ‫ﺑﺮ‬ ‫اﯾﺠﺎد‬
