黄河流域水文分析数据集——流量

该数据集为黄河上游、中游和下游全流域的流量数据集。 流量阈值为15000 汇流分析的主要目的是确定水流的路径。在流向栅格图的基础上生成汇流栅格图,汇流栅格上每个单元的值代表上游汇流区内流入该单元的栅格点总数,即汇入该单元的流入路径数（NIP）。NIP较大的区域可视为河谷,NIP等于0的区域则是较高的地方,可能为流...

This dataset is a flow discharge dataset covering the entire Yellow River basin, including its upper, middle and lower reaches. The flow threshold is set at 15000. The primary objective of confluence analysis is to determine the flow paths of water. The confluence raster map is generated based on the flow direction raster map. The value of each cell in the confluence raster represents the total number of grid cells in the upstream confluence area that flow into this cell, namely the Number of Inflow Paths (NIP). Areas with a larger NIP value can be regarded as river valleys, while regions where NIP equals 0 are relatively high-lying areas, which may be [text truncated].
