This video clearly explains how to calibrate an automatic model. Thank you for taking the time to produce this video which is very useful for new hydrological modeling developers.
Hello, i have a problem with my hydrological model. when i run the optimization, my optimization Nash values display 0 and so does the RMSE. however, the simulated hydrographs fit perfectly. what can i do to solve this problem, please? my production function: SCS curve number my transfer function: SCS unit hydrograph my routing function: Lag
sometimes it may be issue with the program or HMS interface. You can download the time series data and compute the NS and RMSE by yourself. If the hydrographs match well, you should get reasonable values of your metrics. Hope this helps. what version of HEC-HMS are you using? the newest versions are a problem many times.
Hey, i have an issue that is coming always whenever I am checking the results after running the model , the results indicate no values for discharge and volume and also some graphs do not show up , what would you think is the problem causing that ?
I have done with Simulation run, but for Optimization run, I am unable to save the start date and end date, Please resolve this query, thats why I am unable to run Optimization

make sure your initial abstraction is set to zero
شكراً لك لقد استفدنا منك كثيراً عرض جميل وواضح
شكرا

make sure you are using correct format. what version are you using. sometimes the latest version of the model has bugs so try a previous version
Thank you Sir
Thank you sir...
You are amazing
thanks alot sir
Thank you so much Sir. But, can i ask your email? I want to ask my calibration for my thesis🙏
