| Watershed Description: | 4512 km^2 Wunna (Venna) River, which is located in the State of Maharashtra in Central India and drains portions of the Nagpur and Wardha districts, and is a tributary of the Wardha River. The Wunna River basin lies between 20°28' to 21°15'N latitude and 78°19' to 79°06' E longitude of the Wardha Subbasin of the Lower-Godavari Basin (see Figure 1 in the article). |
| Calibration Summary: | The findings of the calibration indicate that APHRODITE performed
well with R2 (0.70) and NSE (0.68) on monthly streamflow (discharge) simulation (Eq. 2 and
Eq. 3). TRMM proved to be the next dataset to be used in the model with excellent NSE and R2
respectively of 0.67 and 0.65. The GPCP dataset also displayed satisfactory results with NSE and R2
respectively of 0.53 and 0.49. CFSR data set of very low of NSE and R2 respectively of 0.40 and 0.39. During validation, APHRODITE was performed well with NSE and R2 of 0.68 and 0.66 respectively; TRMM was performed well with NSE and R2
of
0.58 and 0.56 respectively; GPCP was performed well with NSE and R2
of 0.52 and 0.52
respectively and CFSR performed very poor during validation (NSE = 0.21 and R2
= 0.20). |
| Validation Summary: | GPCP (NSE = 0.50), TRMM (NSE = 0.56), APHRODITE (NSE = 0.66) and CFSR (NSE = 0.20). During validation APHRODITE and TRMM were perfromed well. |
| General Comments: | The focus of this study to assess the suitability of four different rainfall dataset (TRMM, APHRODITE, GPCP
and CFSR) using the SWAT model. |
