Abstract Central to integrated flood risk management is the integration of water management with spatial planning. Existing studies often focus on analyzing the policy instruments in the initiation and planning phases of integrated flood risk management. Little is known, however, about the policy instrument mixes that enable implementation of integrated flood risk management. Therefore, in this article we analyze the Dutch Room for the River program to identify what mixes of policy instruments enable successful integrated flood risk management in the implementation phase. We collected archival and survey data and analyzed 19 implemented projects in the Room for the River program applying Qualitative Comparative Analysis (QCA). We conclude that no single policy instrument is necessary or sufficient for successful implementation. We found three policy instrument mixes: an integrated contract mix, a project management mix, and an outside-government mix.

实施综合洪水风险管理的有效政策工具组合：对“河流空间”计划的分析

摘要 综合洪水风险管理的核心是将水管理与空间规划相结合。现有研究通常侧重于分析综合洪水风险管理的启动和规划阶段的政策工具。然而，人们对能够实施综合洪水风险管理的政策工具组合知之甚少。因此，在本文中，我们分析了荷兰河流计划，以确定哪些政策工具组合能够在实施阶段成功实现综合洪水风险管理。我们收集了档案和调查数据，并应用定性比较分析 (QCA) 分析了“河流之屋”计划中的 19 个已实施项目。我们的结论是，没有单一的政策工具对于成功实施是必要或充分的。
