| Abstract: | Due to their complex nature, river models require extensive calibration in order to achieve reliable model predictions. Manually
fitting the numerous parameters included in this procedure can be a laborious and repetitive process. This paper presents
a new instrument, developed specifically for the automatic calibration of river models based on the software MHYSER. The instrument
is completely autonomous and returns the model with the parameter values giving rise to the smallest difference between the
model-generated observations and the measured observations. It utilises the software PEST to fit continuous calibration parameters
and exceeds the program’s capabilities in order to also fit discontinuous calibration parameters. Testing of the instrument
is accomplished using three models, one of which was developed during a study on the dynamics of sediments on the Romaine
River, situated in the Eastern region of the Province of Quebec. |
