Preparing for Future Flooding is a 30 page summary of the Ministry’s technical report Tools for Estimating the effects of climate change on flood flow. It provides an overview of the expected impacts of climate change on flooding such as changes in rainfall, temperature, sea-level, storminess and sediment transport processes. It provides good practice information and guidance to help local authorities incorporate climate change impacts into flood risk management planning through providing examples of approaches local government has taken.
This guide draws on information presented in Tools for Estimating the Effects of Climate Change on Flood Flow, a 95-page report prepared for the Ministry for the Environment by NIWA. It also draws on information from other guidance, including the Ministry’s technical report A Methodology to Assess the Impacts of Climate Change on Flood Risk and draws on work undertaken by SKM for the Ministry.
