Drainways

This topic includes pathways of wild draining water as well as linear ablation forms resulting from lateral and deep erosion in extreme heavy rain events. These are distinguished according to their depth into three types (Rille, trench and trench).本数据集涵盖极端暴雨事件中形成的野外径流路径，以及由侧向侵蚀与深切侵蚀作用产生的线性侵蚀地貌形态。该类地貌依据其侵蚀深度被划分为三种类型（Rille、trench、trench）。
