Addressing water exploration, quality and management.
Groundwater accounts for roughly 30% of New Zealand’s water usage and is essential for environmental integrity, social well-being and economic productivity.
At GNS Science Hydrogeology Department, our research and research-based consultancy address the critical issues facing groundwater resource management:
How have/will human activities, climate change and other pressures affect New Zealand's groundwater resources?
- What are the hydrogeological and structural characteristics of NZ's aquifer systems?
- What factors are key to maintaining groundwater quality in New Zealand?
- What are the fluxes of key substances into, out of and through NZ's aquifers?
- What are the fluxes of water into, out of and through NZ's aquifers?
- How can we ensure that stakeholders will use our research results appropriately and efficiently?
The SAC research programme aims to develop a suite of innovative methods for rapid and cost-effective characterisation of New Zealand’s groundwater systems. SMART is an acronym for Save Money and Reduce Time.
The GWR programme objectives include: national monitoring of NZ groundwater quality; characterisation of groundwater systems including economics and policy; and application of age tracers and isotopes for understanding the dynamics of hydrologic systems.
This programme aims to improve groundwater models by calibration and validation using hydrochemical, temperature and age tracer data. This programme includes case study areas in the Bay of Plenty, Wellington and Southland regions.
The Ka Tu Te Taniwha – Ka Ora Te Tangata project aims to understand the impacts of development in the Awahou groundwater catchment to ensure the health and wellbeing of the Ngati Rangiwewehi people.
Mapping Groundwater Discharge Into Rivers Using Radon
Understanding how surface waters and groundwaters interact is an integral component of managing the influence of nutrient inputs to water quality. The aim of this research was to establish the potential of radon for measuring groundwater and river water interaction in two North Island, New Zealand gravel bed rivers. Test studies were carried out in the Hutt and Mangatainoka Rivers in the lower North Island.
