3.1.1 Validation of the model with recorded hydrographs
The results obtained by running the model with recorded hydrographs show that even though the water level variation doesn’t always match the pattern of the recorded fluctuations, the peak water level can be reproduced with an accuracy varying between 0.05 and 0.25 m (Figure 1). These results were positive, especially considering that all the test cases were influenced to varying degrees by a dam downstream that imposed a regulating effect on the lake outflow. These preliminary results suggested that this approach, even if very simplistic, could produce sensible outputs for specific events and thus led the research toward testing it with synthetic hydrographs (for ungauged rivers) in order to produce water level frequency curves.
