I’ve had the following problem twice.
The sed_retention, watershed_results_SDR files are missing in the output results of the model, and the running will be stuck or closed in the end.
At the first time, the calibrated parameters k=1.5 and IC0=0.628 were used. The simulation was successful in 2015, but failed in 2018，as showed in tex log file 1.1 and 1.2
On this basis, two adjustments were attempted for the simulation in 2018.
(1) The watershed boundary was replaced by the boundary without lake area, and the simulation is successful. Corresponding tex log file 1.3
(2) Lake area was still inclued in the watershed boundary, but k and IC0 were changed to default 2 and 0.5, and the simulation was successful. Corresponding tex log file 1.4
At the second time, the calibrated parameters k=1.4 and IC0=0.5 (default) were used, the simulation failed in 2010. Corresponding tex log file 2.1.
On this basis, two adjustments were made,
(1) the watershed boundary was changed to one without lakes, the simulation still fails. Corresponding tex log file 2.2
(2) Change k to the default 2.0, and the simulation was successful. Corresponding tex log file 2.3
As we can see, when k and IC0 are set as the default, the simulation succeeds, but some years it succeeds when it’s not the default;
So I was puzzled by these results. What’s the real reason for the failed running?
