Decisions on flood mitigation measures are made more complex with uncertain features of hydrosystem parameters. A decision making framework is developed with the PROMETHEE MCDA technique and applied to a central basin of Jakarta, Indonesia to analyse potential levee alternatives. Expected loss and graduality are formulated as two criteria to reflect the hazard severity with the uncertain rainfall, and the construction cost of various alternative levee design plans represents the expense of the project. This decision framework using an outranking MCDA approach is shown to be able to address uncertainty in rainfall.
