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 | 2.7084×10−3 | 0.53359 | 0.02083 | 96.10% | CDS | 24 | 4.4638×10−3 | 0.59472 | 0.03060 | 94.86% |
