Method: WRI Aqueduct Floods v2 inundation depths sampled at the asset location; damage via the selected depth-damage
function; ExpectedDamage = Σ
j Damage(d
j)/RP
j 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:
