Table 1 Mann-Kendall statistical tests on the Log10 TN vs. Log10 TN:TP and Log10 TP vs. Log10 TN:TP between the two periods before (B-CUD) and after the construction of the upper dam (A-CUD)

From: Modifications of nutrient regime, chlorophyll-a, and trophic state relations in Daechung Reservoir after the construction of an upper dam
