The meteorological parameters of the catchment are the most important dataset for modelling the hydrological processes. The meteorological parameters such as solar radiation (S), relative humidity (RH), wind speed (W), and max–min temperature (Tmax and Tmin) were taken on a daily time scale from MERRA-2 (Table 1), whereas the precipitation data (Figure 2(f)) will be acquired from TRMM and IMD gridded weather data.
