The KINEROS2 model was calibrated for the R23^rd event using the hourly gauged Q and Sat-P. Some significant changes of parameters were implemented in the calibration stage to make the model an acceptable simulator of the real hydrological system. These parameters are summarized in Table 3. Afterwards, the model validation was performed for the R30^th (using Sat-P), R8^th and R31^st (employing Gau-P) events.
