What flood risk does to the probability of default
baseline vs. flood-adjusted vs. flood-adjusted with the selected adaptation standard
Method: WRI Aqueduct Floods v2 inundation depths sampled at the asset location; damage via the selected depth-damage function; ExpectedDamage = Σj Damage(dj)/RPj per flood type (Eq. 3); +99 bps PD per 1 s.d. (0.043) of expected damage; enforced standards −4% PD, policy-only +2% (illustrative). Paper: Assab (2025). All data loads from CSV — swap the files in data/ to update the site.
