This publication, the third module of a resource manual to support the training of planners and practitioners in managing flash flood risk, deals with structural measures. It presents bioengineering techniques, physical measures for slope stabilisation and erosion control, and physical measures for river training. It also presents the concept of integrated flood management as a component of integrated water resource management. It emphasizes that structural measures are most effective and sustainable when implemented together with appropriate non-structural measures. The manual is aimed at junior to mid-level professionals with a civil engineering background working on flash flood risk management at the district level. Flash floods are among the most destructive natural disasters in the Hindu Kush Himalayan region. Flash flood mitigation is generally addressed by community-based organisations, local non-governmental organisations, or district and local-level staff in government organisations. But these groups often lack adequate understanding of the processes causing flash floods and knowledge of flash flood risk management measures.
