Our work

Bringing together leading scientific organisations and regional councils, this project aims to develop a sophisticated computer modelling framework that will enable users to accurately predict how much freshwater is available, where it has come from, and how quickly it moves through New Zealand catchments.
NIWA has established a network of 11 high elevation meteorological stations aiming to gather information about the amount, extent, seasonal nature and long-term change to snow and ice in alpine regions of New Zealand.
Currently there are gaps in understanding of user decision making processes and public needs and requirements for river forecasting in New Zealand. This project aims to bridge NIWA river forecasting aspirations and capabilities with both the public and decision makers’ requirements.

Hydrology Sounds Interesting 2011

The December 2018 New Zealand combined Hydrological and Meteorological Society conference called for a new category of presentation that was short, interesting and artistic. Dr Graeme Smart (NIWA Principal Scientist - Natural Hazards and Hydrodynamics) - took time series of Canterbury hydrologic variables during February 2011 and played these as an orchestral score.

NIWA and IBM today announced a multi-million dollar partnership where NIWA will purchase one of the world’s most powerful supercomputers for use in environmental forecasting.
