Chau Doc (Bassac): will the river rise in the next 7 days? Beta
Beta. New forecast, tested on past years but with only a short live record. Use it as background, not for decisions.
0%–10% chance the river at Chau Doc (Bassac) has its 15-day average level rise 0.25 m or more (tide-adjusted) by 2026-11-07.
Model estimate 0%. In held-out years 1792 past forecasts in this band were followed by a rise 1% of the time.
For comparison: the usual chance for this time of year is 3%; "same as recent days" gives 3%. Based on gauge data up to 2026-10-31 and NASA IMERG rain up to 2026-10-31 (late run).
This gauge is tidal, so we forecast a tide-adjusted level (15-day average) instead of the raw daily level. It is shown publicly only if that forecast beat both baselines on held-out years.
Not a flood warning. Follow official warnings from your national agency and the MRC. A rise can come from rain, tides or dam releases; this does not say which.
How we test it: rules written before fitting (scoreboard and method). Data: Mekong River Commission (MRC) PMFM public dashboard; NASA IMERG rain.
