HydroRIVERS

HydroRIVERS是一个全球河流矢量线网络数据库，包含集水面积至少10平方公里或平均河流流量至少0.1立方米/秒的全球河流。该数据库从15弧秒分辨率的HydroSHEDS核心图层中提取，覆盖全球850万个独立河段，总长度达3590万公里。每个河段包含长度、距源头和海洋出口距离、河流阶数和长期平均流量等有限属性信息，并与HydroBASINS数据库中的子流域进行关联。HydroRIVERS is a global river vector line network database that covers global rivers with a catchment area of at least 10 square kilometers or an average river discharge of at least 0.1 cubic meters per second. It is extracted from the 15-arcsecond resolution HydroSHEDS core layer, encompassing 8.5 million independent river reaches worldwide with a total length of 35.9 million kilometers. Each river reach contains limited attribute information including length, distance from the river source and to the ocean outlet, river order, and long-term average discharge, and is associated with sub-basins from the HydroBASINS database.
