With the increase of operation cycle in long-distance water conveyance project, problem silt or algae residue deposition river channels is becoming more and prominent, especially vicinity some uncommonly used bifurcation outflow gates along project. When reaches certain thickness, it will not only affect quality local bodies, but also seriously normal these gates. In order to alleviate this problem, prevention control project mainly explored from two perspectives: (1) scouring effect on bottom side channel compared by studying different diversion ratios channel; (2) The arc guide wing wall built near junction main channel. simulation conducted at 6 included angles including -10°, -5°, 0°, 5°, 10° 15°, for non-guide wall. incoming flow simulated 280 m3/s general 320 design flow. A total 14 groups experiments are carried out numerical simulation. It can be concluded that, when held constant, a higher ratio results effective sediment 0° has significant junction; cannot play role hinders
