Abstract

Building of Dam from thousands of years BC was known, and the humans with use of them always try to preserve and utilize surface WATER resources, but sedimentation problem always is the most important factor in shortening the useful life of DAMS, and a lot of RESERVOIRs were filled by sediments due to this process and therefore most of DAMS have been abandoned. One of the most important phenomena that affect sedimentation is DENSITY current. Research must be continued to recognize the role of this phenomena in sediment process. In this research the effect of changes in parameters such discharges, concentration and slope gradient in DENSITY CURRENTS were investigated in the CONVERGING CHANNELS. Experiments were carried out in a flume with changeable bed slope, width 72.5 cm, depth 60 cm, Length 6 meter, three convergence angle, three discharge, three concentrations and three bed slope in laboratory models of hydraulic of Shahid Chamran University. The results showed that increase of discharges and slope gradient will increase WATER ENTRAINMENT and increasing of concentration will decrease it. Finally an equation is presented for WATER ENTRAINMENT in each convergent angle.
