preferential flow

The role of rock and root structures in preferential flow within mountainous terrains remains an underexplored area in hydrological research. This study aimed to assess the influence of these structures on preferential flow in the rocky mountainous regions of North China, utilizing computed tomography and dye tracing experiments. 1. rock fragments data 2. root data 3. macropore data 4. prefential flow data岩石与根系结构在山地地形中优先流的作用仍是水文研究中的一个未充分探讨的领域。本研究旨在评估这些结构对中国北方岩石山区优先流的影响，采用计算机断层扫描和染料追踪实验等方法进行评估。数据集包括以下部分：1. 岩石碎片数据；2. 根系数据；3. 裂隙数据；4. 优先流数据。
