Datasets description

 This dataset represents the river network across the entire Yellow River Basin, including its upstream, midstream, and downstream regions. When the confluence flow reaches a certain value, surface water flow is generated. All grids with a confluence flow greater than the threshold value represent potential water flow paths. The network formed by these water flow paths is known as the river network.

 This data is extracted based on a confluence accumulation greater than 15,000 and employs the Strahler method to classify the river network.

Data source description

 Self-produced, the spatial resolution of the original topographic slope dataset for the Yellow River Basin is 30m.

Data processing method

 Extracted using the Hydrology hydrological tool software, it represents a surface runoff overland flow model.

Data quality description

 This dataset has undergone DEM correction, with both planimetric accuracy and elevation accuracy being less than one pixel.
