1. This dataset contains the inter-annual variation data of runoff at the mainstream hydrological stations in the Yellow River Basin. It mainly collects the annual variation data of runoff and the intra-annual monthly runoff transformation data at the mainstream hydrological stations in the Yellow River Basin. Specifically, the monthly runoff variation data for the mainstream of the Yellow River Basin from 2015 to 2019 are presented in separate worksheets for each year.

 2. Dataset Name: Intra-annual and Inter-annual Variation Data of Runoff in the River Basin.xlsx

 3. Attribute Information:

 (1) The inter-annual variation data table has three main attributes: hydrological control station, controlled drainage area, and annual runoff;
