摘要：Coastal cities combine intensive socioeconomicactivities and investments with high exposure to flood hazards. Developingeffective strategies to manage flood risk in coastal cities is often acostly and complicated process. In designing strategies, engineers rely oncomputationally demanding flood simulation models, but they can only comparea limited number of strategies due to computational constraints. This limitsthe efficacy of standard flood simulation models in the crucial conceptualphase of flood risk management. This paper presents the Flood Risk ReductionEvaluation and Screening (FLORES) model, which provides useful riskinformation in this early conceptual phase. FLORES rapidly performs numeroussimulations and compares the impact of many storms, strategies, and futurescenarios. This article presents FLORES and demonstrates its merits in acase study for Beira, Mozambique. Our results demonstrate that expansion ofthe drainage capacity and strengthening of its coastal protection in thesouthwest are crucial components of any effective flood risk managementstrategy for Beira.
