The rainfall with a total height of 103.0 mm starts on 21/12 19:00 and ends on 22/12 22:00 with the highest rainfall peaks occurring on 21/12 21:00 (maximum intensity 10.1 mm/h) and on 22/12 1:00 (17.6 mm/h). With a base flow equal with 1.62 m3/s, the discharge begins to increase approximately 6 hours after the rainfall start with the peak occurring on 22/12 6:00 (37.67 m3/s). After the peak the discharge decreases with some smaller peaks occurring due to rainfall's intensity fluctuation and following them decreases slowly (with a duration of 5.5 days) and stabilizes at 1.00 m3/s. Some small rainfall values occurring during the discharge do not seem to cause variations in the flow.

The rainfall with a total height of 107.1 mm (with rainfall data from Nedousa's station) starts on 21/12 18:45 and ends on 22/12 15:00 with the highest rainfall peaks occurring on 21/12 23:30 (maximum intensity 22.6 mm/h) and on 22/12 1:00 (32.1 mm/h). With a base flow equal with 0.97 m3/s, the discharge begins to increase abruptly 1 hour after the rainfall start with the peak occurring on 22/12 5:00 (6.04 m3/s). After the peak, the observed discharge decreases exponentially (with a duration of 2.5 days) and stabilizes at 1.00 m3/s.
