Dear researchers,
i'm currently preparing a master in urban hydrology on the modelling of a combined sewer system with a national company which bought MIKE URBAN DHI MOUSE and I'm actually stuck with the problem of calibrating automatically the model that i already built (subbasins, conduits, junctions, singularities).Besides, i also imported the stations as a shapefile.
My teacher explained to me that parameters that we have to change iteratively if we do a manual calibration (by trial and error) are the ones of the hydrological model (runoff generation and runoff routing), the hydraulic model, initial losses and the CSOs. But he also told me that MOUSE was able to do all these time-consuming steps automatically.
I would really appreciate if you could please help me concerning the steps to follow or the functions to use in MIKE in order to calibrate the model automatically so that the observed data (flow and water depth from the sensors in the sewer system) pretty match the simulated one. I read all the manual but i didn't find a clear answer to this question.
Thank you very much in advance,
BENHAMMADI Rima.
Hi Rima Benhammadi, have you tried with Auto-calibration tool within MIKE suite? go to file --> new--> select auto-calibration tool. Couple your model setup and specify the parameters with lower and upper bounds to test it with. This Auto-cal tool is bit tricky for specifying the parameter ranges and selecting the trial and error methods. However, you can read it from MIKE auto-cal manual (select a method and hit F1) or you can directly write to MIKE technical support.
BTW, i am Ex- DHI employee and really don't have any information on the updates in this tool. but you should try it out. Good luck!
Dear mister Murugesan Balamurugan ,
thank very much for all your explanations.
Best regards.
Dear Benhammadi Rima, you can use the Auto-calibration tool inside Mike software in order to find the limit of each parameter, after that you can adjust the parameters manually by trail and error in order to get best agreement between the observed and simulated.
Dear mister Saad Shauket ,
thank you very much for your clear and concise answer.
Best regards.
