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

Lakes and reservoirs are an important sources of drinking water for human life. However, numerous quality indexes show seasonal fluctuation under different climatic conditions. We conducted a one-year investigation Taiping Lake in year 2022 to construct relationship between parameters quality. High temperature promotes the growth algae, existence N species could provide essential nutrient substance growing algae. Under irradiation sunlight, algae will consume carbon dioxide through photosynthesis release oxygen which can raise levels water. rapid influence acid-base balance consumption dioxide; thus, resulting increasing pH values. These changes may pose threat
