The results of the adjoint model using CFD and CDS.
| Method | Time step size (h) | Relative magnitude of the cost function | Mean absolute error of observation points | Before assimilation (mg/L) | After assimilation (mg/L) | Rate of decline |
| CFD | 48 | 6.0650×10−3 | 0.24121 | 0.01720 | 92.87% | CDS | 24 | 1.3303×10−2 | 0.28406 | 0.02959 | 89.58% |
