River flow forecasting
Research ProjectNIWA 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. -
Restoration of aquatic ecosystems
Research ProjectThis project aims to increase our knowledge of aquatic ecosystems and their restoration, and apply this to degraded streams, rivers, lakes and estuaries. -
Better runoff and hazard predictions through national-scale snowmelt forecasting
Research ProjectDeveloping a snowmelt forecast system to enable more accurate and confident forecasts of river flow and alpine hazards. -
Future Coasts Aotearoa
Transforming coastal lowland systems threatened by sea-level rise into prosperous communities -
High Frequency Water Quality Monitoring Guidance
Research ProjectA NIWA-led project to support anyone wishing to deploy a water quality sensor in rivers, lakes and estuaries. -
Investigating ecological impacts on freshwater insects from LED streetlight conversions
Research ProjectMany New Zealand cities and towns have switched over to modern LED street lighting. The move will save on operational costs, but little is known what impact artificial streetlights have on flying freshwater insects which are integral to our waterway ecosystems. NIWA investigated the likely impact as part of a four-year MBIE-funded Smart Idea project. -
Effective mitigation systems to manage contaminant losses
Research ProjectNutrients, sediment, and microbial contaminants are mobilized from urban and agricultural landscapes and enter streams, rivers, lakes and estuaries. These contaminants can degrade water quality, ecological health, and cultural values. -
Cultural Keystone Species
Research ProjectA four-year research programme focused on the co-management and restoration of our freshwater taonga species. -
River flow forecasting
Research ProjectNIWA 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. -
Freshwater bioremediation using native mussels - focussed on shallow eutrophic lakes
Research ProjectThe project aim was to harness the filter-feeding capacity of native freshwater mussels on rafts to assist in lake restoration. -
Hauraki Integrated Land-Water Modelling
Research ProjectThe Inner Hauraki Gulf/Tīkapa Moana ecosystem is facing proliferations of algae, de-oxygenation, reduced pH (acidification), reduced water clarity, and muddier sediments arising from historical and future land-derived contaminant inputs. -
eFlows Explorer
Research ProjectThe eFlows Explorer webtool is designed to aid broad-scale river flow management planning across New Zealand
