Hydrological science underpins Forest Flows research
NIWA is part of an international team of researchers contributing to the MBIE-funded Forest Flows programme. Forest Flows is a five-year research programme, led by Scion, looking at how we can create and maintain climate-resilient landscapes to provide beneficial outcomes for all New Zealanders.
New Zealand streamflow depletion model: A tool for sustainable water resource management
Intense competition for water is putting pressure on the life-giving resource, elevating demand for expert research to improve water management systems.
Investigating ecological impacts LED streetlight conversions on freshwater insects
Most New Zealand cities and towns have switched over to modern Light-Emitting Diode (LED) street lighting, which provides improved illumination at lower operational cost.
Barriers to freshwater fish migration
Nearly half of New Zealand's river network is partially or fully inaccessible to migratory fish, a new study shows.
