Abstract The objective of this research is to improve the understanding and recognition of the management challenges to flash flooding hazards and the potential adaptive measures within the arid urban areas through a socio-hydrological framework. Considering the capital of Sudan, Khartoum, as an example of urban arid areas with increasing flash flood risk, the analysis was founded on expert views and opinions collected from a range of different flood management actors following the 2013 and 2014 flash flood events. The qualitative research methods included participant observation, expert interviews and focus groups. The main themes of management challenges recorded included weak institutional capacity, bad governance, limited resources, and poor urban planning. These four themes, in turn, included different types of challenges, among which lack of: civil society engagement and coordination of actors, political will, data and tools, and effective urban development strategy shared the highest number of comments from the professional actors in each theme, respectively. These findings presented a management perspective to the lessons previously established and learned from an impact assessment. Accordingly, the amalgamation of all the lessons learned from the flood research findings enabled a suitable Master Flash Flood Management Plan (MaFFMaP) to be proposed as a final product. This plan would operate within an Integrated Flash Flood Management (IFFM) framework. The facets of the MaFFMaP include steps toward improving the quantity and quality of data resources regarding this hazard, aspects for use of these new datasets within a mixed-measure (structural and non-structural) approach from the authorities, and programmes for building community and civil society capacity through improving awareness and engagement. Furthermore, it is intended that this plan would be a replicable design, which could therefore be adopted and implemented in the wider context of the urban arid regions.

建设抵御山洪暴发的社会水文弹性城市：干旱地区的主要挑战和切实可行的计划

摘要 本研究的目的是通过社会水文框架提高对山洪灾害管理挑战和干旱城市地区潜在适应措施的理解和认识。考虑到苏丹首都喀土穆是山洪暴发风险不断增加的城市干旱地区的一个例子，本分析基于在 2013 年和 2014 年山洪暴发事件后从一系列不同的洪水管理参与者那里收集到的专家意见和意见。定性研究方法包括参与观察、专家访谈和焦点小组。记录的管理挑战的主要主题包括机构能力薄弱、治理不善、资源有限和城市规划不善。反过来，这四个主题包括不同类型的挑战，其中缺乏：民间社会的参与和行动者的协调、政治意愿、数据和工具以及有效的城市发展战略在每个主题中分别获得了专业行动者的最多评论。这些调查结果为先前建立和从影响评估中吸取的经验教训提供了管理视角。因此，综合从洪水研究结果中汲取的所有经验教训，最终提出了一个合适的山洪管理主计划 (MaFFMaP)。该计划将在综合山洪管理 (IFFM) 框架内运作。MaFFMaP 的各个方面包括提高有关该危害的数据资源的数量和质量的步骤，在当局的混合措施（结构性和非结构性）方法中使用这些新数据集的各个方面，以及通过提高认识和参与来建设社区和民间社会能力的计划。此外，该计划旨在成为可复制的设计，因此可以在更广泛的城市干旱地区背景下采用和实施。
