TY - JOUR ID - 1848 TI - HYDRAULIC JUMP IN A DIVERGING CHANNEL WITH AN ADVERSE SLOPE JO - Iranian Journal of Science and Technology Transactions of Civil Engineering JA - IJSTC LA - en SN - 2228-6160 Y1 - 2014 PY - 2014 VL - 38 IS - C1 SP - 111 EP - 121 KW - Hydraulic jump KW - gradually diverging stilling basin KW - adverse bed slope KW - sequent depth KW - Energy loss DO - 10.22099/ijstc.2014.1848 N2 - In this research, the adverse hydraulic jump formed in a gradually expanding stillingbasin of rectangular cross section is investigated both theoretically and experimentally. Theexperiments were conducted in a specially designed model for a wide range of bed slopes anddiverging angles of the basin walls in addition to classic jump for a wide range of Froude numbers.A momentum-based theory is presented to determine the sequent depth ratio. The results show thatthere is good agreement between theoretical and experimental data. Comparison of importantparameters of a diverging hydraulic jump on the adverse slope, such as length, sequent depth andenergy loss, with those in the classic jumps indicated that any increase in the adverse bed slopeand the diverging angle of basin wall would cause a reduction of the sequent depth and relativelength of jump and increase in the relative energy loss in comparison to the classical hydraulicjump.
