| # Repair a river-network sediment transport calculation |
|
|
| An Earth-surface modeling workflow uses the supplied source snapshot to |
| simulate bed-material pulses moving through a river network. The calculation |
| completes, but the resulting downstream history and stored river state do not |
| match the physical behavior described by the supplied material. |
|
|
| Run the public reproduction, study the complete Python source snapshot, and |
| repair the implementation so that the |
| transport calculation, stored material, and tracked sediment motion remain |
| scientifically consistent. The repair must generalize to other river networks, |
| hydraulic conditions, sediment records, and time steps. Do not |
| special-case the supplied fixture or replace the scientific calculation with a |
| fixed report. |
|
|
| Work only in this task directory. The evaluation environment is Linux and has no |
| network access. You may modify files under `source/`. |
|
|
| Use: |
|
|
| ```bash |
| python reproduce.py |
| ``` |
|
|
| The command returns `1` for the reproduced finite scientific inconsistency, `0` |
| after a successful repair, and `2` for a runner or environment failure. |
