Suspended sediment load to water bodies is governed by climate change and human activities. Fluctuation in water temperature due to climate change affects the suspended sediment deposition. In this study, laboratory experiments are conducted to understand the influence of water temperature on suspended sediment concentration and its particle size in ionized water. Experiments are conducted in an annular flume with kaolin (d50 = 6.9 μm) and ionized water by changing water temperature (30, 40, and 50 °C), bed shear stress (0.01, 0.05, 0.10, and 0.20 N/m2), and initial suspended sediment concentration (1, 2, and 4 g/L). Results show that rise in water temperature causes decrease in both settling flux and degree of deposition, but particle size increases. Variation in initial suspended sediment concentration has an inverse effect on settling flux and has minimum influence on degree of deposition. Size of suspended sediments showed direct relation with initial suspended sediment concentration.

水温对离子水中悬浮沉积物浓度和粒径的影响

水体的悬浮泥沙负荷受气候变化和人类活动的控制。气候变化引起的水温波动会影响悬浮沉积物的沉积。本研究通过实验室实验，了解水温对离子水中悬浮泥沙浓度及其粒径的影响。通过改变水温（30、40 和 50 °C）、床剪切应力（0.01、0.05、0.10 和 0.20 N/m2），在具有高岭土（d50 = 6.9 μm）和离子水的环形水槽中进行实验，和初始悬浮泥沙浓度（1、2 和 4 g/L）。结果表明，水温升高导致沉降通量和沉积程度降低，但颗粒尺寸增加。初始悬浮泥沙浓度的变化对沉降通量有相反的影响，对沉积程度的影响最小。悬浮泥沙的大小与初始悬浮泥沙浓度有直接关系。
