Did you select the correct point for calibration of the model?

Are these dry and wet years where there is more rain? I have to analyze it.

I think you need to provide some more background on your model and data.

- What is the source, quality and treatment (e.g. interpolation) of your input and forcing data?

- What is your parametrization (at least for the most important ones)?

- What is the source, quality and treatment (e.g. interpolation) of your measured data?

- What is the time scale?

- What are we looking at in the image? Outflow?

In any case, there seems to be some negative trend in your output. Maybe not statistically significant, but still. Do you see this on your forcing data?

Thank you very much for help.

I was able to calibrate with satisfactory results. But I would like to have an even better NS. I have been standing against the wall for several days.

My calibration facility is located in the upland area in Poland. About 170 to 220 meters above sea level. The area is strongly diversified in terms of height, undulated and cut with deep ravines. Precipitation is about 600 mm per year. PET is a 650 mm per year and eavpotranspiration / transpiration is a 450 mm per year. Advantage of soils with silt loam (SiL). The main landuse is CRDY - 65 percent of the area and FRSD - 10 percent. Slope is 0 - 6 percent - about 75 percent of the area. There is snow cover in winter.

I would like to ask the group for advice on which parameters I can take into account or what to check.

The graph shows the flow in m3 / s. The blue line is observation. Red is a simulation.

Best regards
