POST app.rid.go.th/reservoir/api/dams (open, archive >=2009) collected hourly into rid_dams + rid_reservoir_daily; backfill script fetches only missing days so reruns repair holes and are safe alongside the live collector. /api/stats counts the new table via an engine fallback that works when HII collection is disabled. Mae Ngat (DAM_ID 200103) hit 113% usable capacity with ~19 MCM/day inflow in the Oct 2024 flood — candidate features for the next retrain.

"""Backfill rid_reservoir_daily with RID large-dam history (Mae Ngat et al.).
|
|
|
|
One request per day against app.rid.go.th/reservoir/api/dams (archive reaches
|
|
back to at least 2009). Days already stored are skipped, so reruns only fetch
|
|
what is missing — safe alongside the hourly live collector, and a rerun
|
|
repairs holes left by transient failures.
|
|
|
|
Usage:
|
|
uv run scripts/backfill_rid_reservoir.py # missing days since 2018-08-01
|
|
uv run scripts/backfill_rid_reservoir.py --start 2015-01-01
|
|
uv run scripts/backfill_rid_reservoir.py --db-url postgresql://...
