The report discusses an experimental decision-making simulation session applied to a flood protection case study against the backdrop of flood risks reinforced by climate change. A diverse set of interest groups was represented in the session that was facilitated by risk analysts using groupware. The purpose of the session was to test the decision analytic process, to learn about stakeholders' tendencies towards types of solutions and their possible underlying explanations. Therefore quantitative ratings have limited value in this case. The exercise is part of a larger study (TOLERATE) concerning socio-economic impacts of climate change enhanced extreme weather conditions.
