Toolbox output

[Ren okumura]

Hi, all

Now, I've tried to calibrate my SWAT+ model. 

However, I'd like to ask about sediment observation data.

Now, my obserbaton data is SS (t & ppm), and  I calculated volume of sediment discharge(m^3/sec) by using river flow and density of sediment. And then, I tried to calibrate my sediment discharge with my obserbation data(m^3/sec), but simulated value toolbox shown is very different from mine. I selected both of river sediment and sediment yield. Is there any mistake in my calculation of observationdata?

Could you tell me what sediment yield and river sediment indicate?

In addition, I tried to calibrate mine with river flow data which has less than 20 data. The result of NSE is negative value. Does it mean  my data is too few to calibrate model?

Thanks,
