| Watershed Description: | 1,384 km^2 Dender River, located in Belgium. |
| Calibration Summary: | 1994 graphical simulated vs. measured flow, DO, nitrate, ammonia, & BOD results presented |
| Validation Summary: | |
| General Comments: | A two-step procedure is described and applied that consists of a sensitivity analysis, that is used to define the variables/parameters of interest, followed by auto-calibration. The sensitivity analysis was based one-factor-at-a-time (OAT) using 129 parameters; a ranked order for the sensitivity of each parameter within the objective functions is provided, in terms of impact on the output variables. 3,000 simulations were performed for the autocalibration, which was based on the Shuffled Complex Evolution method. |
