Modelling

Latest news

The most detailed seafloor mapping of a coastal region off New Zealand has been completed in Marlborough.
Massive increases in computing power are allowing NIWA scientists to not only analyse more data, faster, but also to envisage completely new experiments.
Tropical cyclones forming in the south-west Pacific are becoming less frequent but those that do form are likely to be more severe.

New Zealand’s coast is sculpted by ocean waves. Some wave conditions bring joy to surfers and beachgoers, but, at other times, waves can cause major hazards at sea or along the shore.

Our work

NIWA hosted an IPBES workshop entitled “Visions for nature and nature’s contributions to people for the 21st century” held from 4-8 September 2017 in Auckland.
NIWA has developed an Urban Stormwater Contaminant (USC) model to enable urban planners to predict sedimentation and heavy metal accumulation in estuaries and identify problem areas in order to target mitigation measures.

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

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.

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.

NIWA answers a wide range of scientific questions using ocean modelling. These models can be linked to well established weather forecasting models to predict ocean temperature, sea level and the dispersal of pollution.

Understanding how material released into the ocean spreads is very important in the case of oil spills, sediment transport and the release of invasive species. 

This research project focusses on modelling atmospheric chemistry and climate from the surface to the top of the stratosphere, using sophisticated chemistry-climate models.

Welcome to NIWA's third Alumni Update – an e-newsletter for past NIWA employees.

Many of New Zealand's rivers fail to meet national guidelines for nutrient levels. NIWA has developed the Catchment Land Use & Environmental Sustainability (CLUES) estuary tool to predict the effects of land use on estuarine nutrient concentrations.

The return of the upgraded RV Tangaroa represents a huge advancement for New Zealand science and exploration

NIWA today welcomed home RV Tangaroa, New Zealand’s only deepwater research vessel, after a $20 million dollar upgrade to enhance its ocean science and survey capabilities.

Welcome to NIWA's second Alumni Update – an e-newsletter for past NIWA employees.

Land Information New Zealand (LINZ) and National Institute of Water & Atmosphere (NIWA) today launched a new web portal providing free public access to data gathered by the Bay of Islands Ocean Survey 20/20 project.
