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.
