Seven-day maximum flow at the LMRB during 2001–2015 Mann Kendall trend analysis. The μ is the arithmetic mean of the seven-day maximum flow (7QMAX) in millimeter per day, τ (tau) is Kendall’s tau correlation coefficient, p-value is 2 sided-test, and trend is Significant when (p ≤ 0.05). Country codes are similar to descriptions in Table 2.
