The invention provides a testing device for simulating and observing starting of viscous sediment and a testing method thereof. The testing device comprises an annular water groove body, a base, a rotary powering and lifting system, a flow rate measuring system, a sampling device and an image observing system, the annular water groove body is formed in the base, the rotary powering and lifting system is fixed on the right side of the base, the flow rate measuring system and the sampling device are fixed on the outer wall of the annular water groove body, and the image observing system is fixedon the left side of the base. By means of the testing device, the existing problems of natural sedimentation difference and larger human impact of existing experimental research of the starting of viscous sediment are solved. 本发明提供种模拟和观测粘性泥沙起动的试验装置及其试验方法，试验装置包括环形水槽主体、底座、旋转动力和升降系统、流速测量系统、采样装置和图像观测系统，所述环形水槽主体置于底座上，所述旋转动力和升降系统固定在底座右侧，所述流速测量系统和采样装置固定在环形水槽主体外壁上，所述图像观测系统固定在底座的左侧，本发明解决了现有粘性泥沙起动试验研究存在的与自然落淤有差异和人为影响较大的问题。
