Implication

Nationally consistent flood maps reveal future flood risks in rural areas of Aotearoa New Zealand, indicating the need for improved policy and planning.

Key Points

This research aims to assess flood hazards in Aotearoa New Zealand under current and future climate conditions.
Developed flood maps based on a semi-automatic workflow that links multiple models.
Used hydrological modelling to route rainfall for 1% AEP design storm events.
Generated flood hazard maps for climate scenarios representing increases of 1°C, 2°C, and 3°C.
Flood maps illustrate maximum water depth, maximum water elevation, and depth times velocity hazard layers.
Mapping provides essential insights into rural flood hazards previously unassessed.
Maps serve as a consistent national flood risk assessment tool, supporting policy development.
