| Watershed Description: | 10,908.88 km^2 Vilija river, which is situated mostly in Belarus and holds the upper basin of Neris River, which is a tributary to Nemunas River. The finalized Vilija model consists of 647 sub-basins and 1,584 HRUs. |
| Calibration Summary: | Good model performance for monthly (calibration R^2 = 0.80, NS = 0.83) and daily (calibration R^2 = 0.66, NS = 0.66) flow. Satisfactory performance results were achieved in modeling monthly loads of suspended sediments (calibration R^2 = 0.4, NS = 0.44), total phosphorus (calibration R^2 = 0.71, NS = 0.61) and total nitrogen (calibration R^2 = 0.55, NS = 0.42) |
| Validation Summary: | Good model performance for monthly flow validation R^2 = 0.80, NS = 0.76, and daily validation R^2 = 0.67, NS = 0.66. Satisfactory performance results were achieved in modeling monthly loads of suspended sediments (validation R^2 = 0.58, NS = 0.34), total phosphorus (validation R^2 = 0.53, NS = 0.56) and total nitrogen (validation R^2 = 0.48, NS = 0.4) |
