Flood Risk Management Approaches

The Japanese Ministry of Land, Infrastructure, Transport and Tourism (MLIT), the Dutch Rijkswaterstaat, the United Kingdom Environment Agency, and the United States Army Corps of Engineers agreed in 2009 to develop a document to explore risk-informed approaches as being practiced and developed primarily in those four countries. This document, the result of that collaboration, reflects contributions from agencies within the four participating nations but is not an official position of any government or international organization. It is organized around a conceptual framework developed to encompass flood risk drivers, risk assessment, and the source-path-receptor concept; the flood risk management cycle with its overarching policies and supporting players and mechanisms; and the adaptive management cycle of maintenance, monitoring, evaluation, and adjustment over time. Despite their varied histories and circumstances, the four countries face similar key challenges. The approaches presented comprise a collective set of best practices among the four countries, with individual and approaches understandably tailored to meet specific country needs.
