Rize basin - Flow data analysis summary Here you can find the detailed data used and results of SWAT model simulation. We have used four calibration techniques to get the best model flow simulation. These are: (1) calibration using gauge data only from downstream area (DC), (2) calibration using gauge data only from upstream area (UC), (3) calibration using gauge data both upstream and downstream areas of the basin (Multi-Gauge Calibration – MGC), and (4) calibration using gauge data first from upstream area only, then using the data from the downstream area sequentially (UCDC).
