泥石流野外沟道实验数据

实验过程中，通过皮尺测量各个堵塞体的尺寸形态，位置间距分布；通过标尺测量泥石流沿程运动过程中泥位深度的变化；通过浮标法测量泥石流沿程的运动速度；通过Sony高清摄像机记录整个实验过程；通过沿程取样分析泥石流沿程的产输沙变化。

During the experimental process, the dimensions, shapes and spatial distribution of positions and intervals of each blocking body were measured with a tape measure; variations in mud level depth during the along-path movement of debris flows were measured using a scale rod; the along-path movement speed of debris flows was measured via the buoy method; the entire experimental process was recorded using Sony high-definition cameras; and variations in sediment production and transportation along the debris flow path were analyzed through along-path sampling.
