Good day:
I'm calibrating Sediment data in Canadian watershed located in Eastern Canada where we have Snow accumulation from December to April every year. My observed data is from May to November for 2022 and 2023 and will have more data in 2024. I use a turbidimeter that records the data in mVolt and we do sediment rating curve to convert the mVolt to mg/L using a linear function (as best in R2).
Now I'm in the process to calibrate my observed data (2022-2023) along with flow data (already calibrated (KGE=81%/NSE=62%)) using SWAT-CUP. I choose the Routing Method#2 as the best one I got. No I'm having difficulties calibrating the sediments as it won't align with observed data (I have an overestimated results) ; please see attached.
Any help will be much appreciated. Many thanks!
