Hazards

NIWA is using machine learning to forecast flood inundation in a fraction of the time required to run physical models. 

Researchers created national sea-level risk profiles for populations, buildings, croplands & infrastructure under present & future climate scenarios.

Floods are New Zealand’s most frequent and costly natural disaster. Fast and accurate forecasting of flood impacts is crucial for reducing the risk to life, property, and infrastructure.

NIWA is using updated climate projections to help New Zealanders better understand climate-related risks.

NIWA scientists have mapped the whole of Lake Wānaka in incredible detail.  

Scientists have found evidence of sediment impacts on seafloor ecosystems following Cyclone Gabrielle.

Developing a snowmelt forecast system to enable more accurate and confident forecasts of river flow and alpine hazards.

Transforming coastal lowland systems threatened by sea-level rise into prosperous communities

In this activity, you will play NIWA's online serious game, Township Flood Challenge.

Developed for teachers, these lessons offer an engaging way to learn about Aotearoa’s weather and climate.

Climate adaptation resources for teachers

A new study has comprehensively mapped the immediate after effects of the January 2022 eruption of Hunga Tonga - Hunga Ha’apai, highlighting the risks of similar events.
