Run times
Run times for models built with a given tool can vary considerably with the size and complexity of the set-up, the number of timesteps in the run, and the computer being used. This makes is difficult to generalise, however, due to their relative simplicity WRSM, SPATSIM, and ACRU4 models in these exercises generally ran in a matter of a few minutes for a 30 year run, while the ArcSWAT and MIKE-SHE models could range from 15 minutes to several hours to complete this.
The run times have import particularly for parameter adjustment testing, limiting how much can be done in the time available for a project. However, the tools that have long run times, as well as SPATSIM, have made the parameter adjustment process quick and allow batch run facilities. Once set-up time-consuming testing runs can be ongoing without manual intervention needed from the modeller, freeing their time for other work. Although WRSM and ACRU4 run quickly, the process of making parameter adjustments in the model set-up to be tested takes a long time and a lot of manual effort as described above.
