2.3 Low drainage period (March 20th – August 31st)
During the low drainage period, only two rainfall events generated runoff (May 11th and June 4th). They are two storm events of 35.2 mm and 28.4 mm with maximum rainfall intensities of 14.4 mm h-1 and 60.0 mm h-1, respectively. During the five days before these events, the cumulated rainfall was only 1.8 mm and 2.8 mm, respectively. Therefore, runoff events that occurred during the low drainage period are generated by rainfall events combining high cumulated rainfall, high rainfall intensities and very little antecedent rainfall in comparison with the intense drainage period.
