Countries in the Hindu Kush Himalayan region generally lack policies, strategies and plans which deal specifically with flash floods. The purpose of the case studies in this report is to create a knowledge base on flash flood processes in different parts of the Hindu Kush Himalayan region. The report examines the region’s diverse climatic and socioeconomic conditions in order to understand existing flash flood risk management mechanisms, including policies and institutional mechanisms, and increase awareness about flash floods. The eight case studies were conducted in Xichang and Niujuangou in Sichuan, China; Dhemaji District in Assam, India; the Bhote Koshi/Sun Koshi basin (two case studies), Lal Bakaiya and Madi in Nepal; and Chitral District in Pakistan. This report contains a summary of each case study, as well as an overview of the status of flash flood risk management in the region and a list of regional recommendations for policymakers.
