If you think science and art have nothing in common, think again. At environmental science institute NIWA, it’s all about one inspiring the other.
Now back on dry land, Voyage Leader Richard O'Driscoll reflects on the final days of RV Tangaroa's 2015 Antarctica expedition.

The New Zealand Hydrological Society Conference takes place in Nelson this week. The theme for the conference is "Water: Know your limits". Water conservation and management is a hot topic.

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.

Our work

NIWA is developing a national river flow forecasting tool for New Zealand that aims to support and strengthen our planning for and response to extreme rainfall events.
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.
Bringing together leading scientific organisations and regional councils, this project develops 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 in 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.

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.

The New Zealand Hydrological Society Conference takes place in Nelson this week. The theme for the conference is "Water: Know your limits". Water conservation and management is a hot topic.

These are some recent publications related to the Environmental flows programme.

New Zealanders are increasingly demanding better information on how much water is in our rivers and groundwater aquifers, how that has changed over time and how it might change in the future. This programme will increase our understanding of the hydrological cycle: the quantity of freshwater in our rivers and groundwater systems, where that water came from and how long it took to get there.
