Fig. 1. Location of (a) the study area in China and (b) hydrological station and rain gauging stations in TRB. The drainage area controlled by Liaoyang Station is surrounded by the red line, while the entire basin is surrounded by the black line.
Fig. 2. Monthly Streamflow distribution under natural conditions.
Fig. 3. Schematic diagram of the definitions of ecosurplus and ecodeficit.
Fig. 4. Annual and seasonal FDC scatter plots before and after the construction of the reservoir: (a) year, (b) spring, (c) summer, (d) autumn, and (e) winter.
Fig. 5. Variations in eco-flow indicators and precipitation anomalies: (a) year, (b) spring, (c) summer, (d) autumn, and (e) winter.
Fig. 6. Boxplot of the correlation coefficients between the 33 IHAs
Fig. 7. Temporal variation in the ERHIs: (a) mean flow in May, (b) 30-day minimum, (c) base flow index, (d) date of minimum, (e) high pulse duration, and (f) number of reversals. The dotted line is the Loess function fitting curve, and the black vertical line is the date when the SWR completed.
