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.
