Answer. Screen the 100-year daily-mean flood at Seine at Paris-Austerlitz, France; identify estimator uncertainty and limitations: 100-year return level, GEV (L-moments) 1951 m3/s (not established). The 100-year return level from 20 annual maxima: GEV by L-moments 1,951 m3/s; Log-Pearson III 1,828 m3/s (90 % confidence interval 1,513 to 2,208 m3/s); bootstrap GEV 1,839 m3/s (90 % confidence interval 1,375 to 2,478 m3/s). Mann-Kendall on the annual maxima: not significant at the 5 % level (p = 0.347, Sen's slope 9.298 m3/s per year over 20 years). The record at Seine at Paris-Austerlitz, France (hubeau_hydrometrie F700000103) runs from 2006-01-28 to 2026-09-21 (20.6 years, discharge in m3/s). The two fits differ by 6%.

Screen the 100-year daily-mean flood at Seine at Paris-Austerlitz, France; identify estimator uncertainty and limitations.. The record: Seine at Paris-Austerlitz, France (hubeau_hydrometrie F700000103), 20.6 years. 1 step(s) ran (None plan, playbook flood_risk); 4 of 5 gates passed. Screen the 100-year daily-mean flood at Seine at Paris-Austerlitz, France; identify estimator uncertainty and limitations: 100-year return level, GEV (L-moments) 1951 m3/s (not established). 1 point(s) are listed under what this study does not establish.
Screen the 100-year daily-mean flood at Seine at Paris-Austerlitz, France; identify estimator uncertainty and limitations: 100-year return level, GEV (L-moments) 1951 m3/s (not established). It holds under these conditions: The annual maxima are independent and drawn from a stationary distribution.; Daily mean maxima can understate instantaneous flood peaks.. Limitations and unresolved checks: step s1 did not pass max_return_period_factor: T = 100 years against a cap of about 60 years (3 times 20 years of record): beyond the cap, an extrapolation; Maintainer reproduction; independent hydrologist review pending.; Daily mean maxima are not instantaneous annual peaks or a certified design flood.. The grade applies to primary result and applicable supporting checks. What would change it: flood_frequency (s1) establishing its result: gate failed: max_return_period_factor (T = 100 years against a cap of about 60 years (3 times 20 years of record): beyond the cap, an extrapolation); the annual peak series of a nearby long gauge, or a regional growth curve: a regional curve keeps the estimate indicative but bounded. The crew would ask for the annual peak series of a nearby long gauge, or a regional growth curve: a regional curve keeps the estimate indicative but bounded.

1. Compare GEV L-moments, LP3 and GEV MLE quantiles on complete-year daily maxima.
Step s1: `flood_frequency(source='hubeau_hydrometrie', station_id='F700000103', bootstrap_ci=True)`, method at_site_flood_frequency; gates: min_years 20 on ffa.n_years; unit_present on unit; max_return_period_factor 3 on ffa.n_years; spread_within 0.25 on ffa.fits.gev_lmoments.q, ffa.fits.lp3.q; trend_on_series 0.05 on ffa.amax_trend.
Assumptions: Independent stationary annual maxima..
The record at Seine at Paris-Austerlitz, France (hubeau_hydrometrie F700000103) runs from 2006-01-28 to 2026-09-21 (20.6 years, discharge in m3/s). Mann-Kendall on the annual maxima: not significant at the 5 % level (p = 0.347, Sen's slope 9.298 m3/s per year over 20 years). The 100-year return level from 20 annual maxima: GEV by L-moments 1,951 m3/s; Log-Pearson III 1,828 m3/s (90 % confidence interval 1,513 to 2,208 m3/s); bootstrap GEV 1,839 m3/s (90 % confidence interval 1,375 to 2,478 m3/s). The two fits differ by 6%. Flow duration: the flow exceeded on 95 % of days is 96.35 m3/s, the median 227.3 m3/s, the flow exceeded on 10 % of days 675.2 m3/s. Gates: min_years passed (20 years of record, 20 needed); unit_present passed (unit m3/s); max_return_period_factor FAILED (T = 100 years against a cap of about 60 years (3 times 20 years of record): beyond the cap, an extrapolation); spread_within passed (spread 6% between 1,951, 1,828 (25% allowed) at T = 100 years); trend_on_series passed (Mann-Kendall on the annual maxima: p = 0.347, tau = 0.16: no trend at the 0.05 level).

Caveats, verbatim from the playbook:
- Maintainer reproduction; independent hydrologist review pending.
- Daily mean maxima are not instantaneous annual peaks or a certified design flood.
- No catchment regulation, channel topology or model/gauge comparability was established.
- Re-run live uses current observations; use the retained CSV and this script for reproduction.
- Step s1, gate max_return_period_factor: T = 100 years against a cap of about 60 years (3 times 20 years of record): beyond the cap, an extrapolation
- Maintainer reproduction; independent hydrologist review pending.
- Daily mean maxima are not instantaneous annual peaks or a certified design flood.
- No catchment regulation, channel topology or model/gauge comparability was established.
- Re-run live uses current observations; use the retained CSV and this script for reproduction.
- Adopt this as the answer to the decision: Screen the 100-year daily-mean flood at Seine at Paris-Austerlitz, France; identify estimator uncertainty and limitations: 100-year return level, GEV (L-moments) 1951 m3/s (not established).
- To firm it up: flood_frequency (s1) establishing its result: gate failed: max_return_period_factor (T = 100 years against a cap of about 60 years (3 times 20 years of record): beyond the cap, an extrapolation).
- To firm it up: the annual peak series of a nearby long gauge, or a regional growth curve: a regional curve keeps the estimate indicative but bounded.
- Obtain the annual peak series of a nearby long gauge, or a regional growth curve: a regional curve keeps the estimate indicative but bounded.
- Read the numbers with this caveat: Maintainer reproduction; independent hydrologist review pending.
