4. Results and Discussion
To understand the impacts of the construction of reservoirs on the changes in hydrological processes during the flood season in the Qinhe River Basin, five reservoirs associated with the main tributary of the Qinhe River that were built after 1950, were investigated. The runoff, actual evaporation, soil water, and NDVI data for the baseline period, change period I, and change period II for sub-basins hosting the five reservoirs were evaluated, and the differences in these parameters between the sub–basins and the Qinhe River Basin were analyzed.
