Early warning systems, insurance and behaviour change can complement protect and accommodate measures to limit residual risk . Early warning systems have high monetary benefits . Behavioural adaptation to flooding relies on recognition of the threat and capacity to respond, both of which are often lacking . Flood risk insurance and compensation systems vary across European countries, ranging from post-disaster payments by governments and compulsory flood insurance, to public-private partnerships where the state acts as reinsurer . Risk-based insurance premiums can induce risk- averting behaviour but may become unaffordable to poor households and some households in high-risk zones . Increasing future flood risks due to both climatic and socioeconomic change could overburden government budgets  , resulting in unavailable or unaffordable insurance for private customers , and underfunding and insufficient solvency of insurance companies . Local knowledge about disastrous flood events in the past can be lost across generations, leading to -settlement in flood-prone areas .
