| Model: | SWAT |
| Broad Application Category: | hydrologic only |
| Primary Application Category: | rice paddy dynamics and/or production |
| Secondary Application Category: | depressional (pothole, wetland or pond) effects and/or processes |
| Watershed Description: | The Arata River watershed in central Japan. The area was approximately 3 km^2, of which 56.4% was upland fields and 18.0% was paddy fields. |
| Calibration Summary: | The CN approach: NSE=0.58, R2=0.66, RMSE=4.88(mm d−1), PBIAS=16%.
The pothole approach: NSE=‒4.02, R2=0.57, RMSE=10.50(mm d−1), PBIAS=7%. |
| Validation Summary: | The CN approach: NSE=0.65, R2=0.65, RMSE=7.14(mm d−1), PBIAS=0%.
The pothole approach: NSE=-0.13, R2=0.55, RMSE=12.17(mm d−1), PBIAS=10%. |
| General Comments: | The CN approach: Rice paddy fields were simulated by the curve number method.
The pothole approach: Rice paddy fields were simulated by the pothole module. |
