The Yellow River is the second longest river in China, and the sediment problem of the Yellow River has attracted the attention of people all over the world. This data is based on the 1:4 million River vector map of the whole country, which is cut from the upper Yellow River basin boundary. River vector map is one of the key elements to extract basin boundary from topographic map, and it is also the key element to do flood and sediment evolution.
This map is stored in ArcGIS,. SHP file, including vector map of main stream and tributary from the source area of Yellow River to Toudaoguai. River vector map is one of the key elements to extract basin boundary from topographic map, and it is also the key element to do flood evolution and sediment evolution.

Vector map of 1:4 million rivers in China
According to the 1:4 million River vector map of China as the base map, it is cut by the upper Yellow River basin boundary
Because the gradient from sanhuhekou to Hekou town is very small, there is a certain error in the basin boundary.
