Floods are the most frequent and damaging of all natural hazards globally. Between 1994 and 2013, floods accounted for 43% of all recorded natural events, affecting nearly 2.5 billion people. The objective of this document is to present five principles and implementation guidance for planning, such as evaluation, design, and implementation of nature-based solutions for flood risk management as an alternative to or complementary to conventional engineering measures.
