I created a QSWAT hydrological model and the simulated daily runoff values in cubic meters per second are extremely higher. Does anyone have an idea what is causing this problem? #QSWAT #Hydrological_model
Dear Joshua,
Have you calibrated the model for your case study? Are you sure about the calibration and validation process? How about your observation data? you need to recheck your data and modeling stages.
I strongly suggest you consider the "sensitivity analysis stage" in your calculations. it does not only let you know how much each input parameter affects your daily runoff, but you probably be able to infer what is the most impactful parameter in your case study. After sensitivity analysis, you can have a meaningful calibration and the calibrated input parameters will make sense, as well as discharge results.
By the way, I can guess your extremely high values may be related to the soil infiltration rate and your soil data.
