The rainfall with a total height of 74.1 mm starts on 21/12 20:15 and ends on 24/12 07:30 and the peaks occur on 22/12 03:00 (maximum intensity 7.44 mm/h), on 22/12 09:45 (6.64 mm/h), on 22/12 14:15 (6.16 mm/h) and on 23/12 19:00 (5.52 mm/h). The discharge begins 15 hours and 30 minutes after the rainfall's start (22/12 10:45) and increases abruptly until it reaches 2.45 m3/s (22/12 13:45). After that peak, it decreases due to the decrease in rainfall's intensity and, following the rainfall's profile, increases until it reaches 4.37 m3/s (22/12 16:15). Next, the discharge decreases (following a decline in rainfall's intensity) and stabilizes approximately at 1 m3/s where it starts to increase again until it reaches its highest peak (4.70 m3/s, 23/12 17:00). After a slow discharge it reaches its zero value on 25/12 12:45.
