黄河流域水文分析数据集——水流长度

该数据集为黄河上游、中游和下游全流域的水流长度数据集。   水流长度是指地面上一点沿水流方向到其流向起点〈终点）间的最大地面距离在水平面的投影长度。水流长度在水文中是水土保持的主要因子。其他条件相同时，水力侵蚀的强度依据水流经过的坡的长度来决定，坡面...

This dataset is a stream length dataset covering the entire basin of the upper, middle and lower reaches of the Yellow River.
Stream length is defined as the projected length on the horizontal plane of the maximum ground distance between a point on the Earth's surface and the starting (or ending) point of the flow direction along the flow path. Stream length is a primary factor for soil and water conservation in hydrology. Under otherwise identical conditions, the intensity of hydraulic erosion is determined by the length of the slope over which the water flows, and the slope...
