Figure 2.
Panels a to d plot discharge against time from 2000 to 2024. The vertical axis ranges from 0 to 40,000 cubic metres per second. Panel a contains variable seasonal peaks, including the highest peak near 2019, and a rising Sen slope with beta equal to 10.9. Panel b contains frequent annual peaks, generally between about 20,000 and 36,000 cubic metres per second, with beta equal to 2.06. Panel c contains repeated peaks reaching nearly 40,000 cubic metres per second, followed by lower peaks after 2019, with beta equal to 1.98. Panel d contains regular fluctuations, mostly below 25,000 cubic metres per second, and increases towards 2024, with beta equal to 2.70.Discharge trends at (a) Luang Prabang, (b) Pakse, (c) Mukdahan and (d) Tan Chau during 2000–2024
