Latest news

Preliminary analysis by NIWA climate scientists has shown that the recent Canterbury rainfall was so extreme in some inland places that it could be expected to happen only once every 200 years.
The prodigious rainmaker that hit Canterbury earlier this month saw NIWA field teams out in the elements collecting flood data from bridges, cableways and jetboat gaugings.
A NIWA scientist is asking for the help of skiers, mountaineers and alpine professionals to collect snow for a new research project.
Environmental monitoring technician Patrick Butler has spent hours travelling between the upper and lower reaches of Canterbury’s Waimakariri and Hurunui Rivers. His mission – river water quality sampling.

The eFlows Explorer webtool is designed to aid broad-scale river flow management planning across 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.
The New Zealand Fish Passage Guidelines sets out recommended practice for the design of instream infrastructure to provide for fish passage.
New Zealand’s freshwater and estuarine resources provide significant cultural, economic, social, and environmental benefits. Competition for the use of these resources is intensifying, and many rivers, lakes and estuaries are now degraded.

Modelling vegetation-impacted morphodynamics in braided rivers
NIWA is developing numerical models for predicting how the morphology of braided rivers responds to flow regulation and invasive exotic woody vegetation.

New information on how rivers will flood during extreme weather will soon be available to help communities become safer and reduce the costs of natural disasters.

The Hydrological Society & The Meteorological Society of NZ joint conference

19 November 2013 to 22 November 2013

NIWA is sponsoring The Hydrological Society & The Meteorological Society of NZ joint conference

The theme of this year’s conference is Water and Weather: Solutions for health, wealth and environment.

The conference is being held in Palmerston North, and will attract scientists, technicians, consultants, hydrologists, climatologists, students, resource managers and many others. 

Welcome to Freshwater Update 57, with the latest info from our Freshwater and Estuaries centre.

The ability to properly manage our freshwater resources requires a solid understanding of the flora and fauna which live in and interact with them.

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