New low-cost groundwater age tracers for characterisation of the water dynamics in aquifers

This project is part of the Smart Aquifer Characterisation (SAC) Programme, which aims to develop innovative methods to characterise groundwater systems in a cost-effective and rapid way.



Characterisation of groundwater-surfacewater interaction at Whakaipo and Whangamata Bays, Lake Taupo, Torepatutahi Stream, Broadlands and Nga Awa Purua Rapids to River Road, Waikato River

Characterisation of groundwater-surface water interaction at Whakaipo and Whangamata Bays, Lake Taupo, Torepatutahi Stream, Broadlands and Nga Awa Purua Rapids to River Road, Waikato River, using Satellite TIR Imagery, Airborne TIR Imagery, FODTS and Water Hydrochemistry and Age.



A nation-wide model of rainfall recharge to groundwater for New Zealand

The project aims to model how much rainwater enters the groundwater across New Zealand. Rainwater which drains through the soil and recharges the groundwater is known as rainfall recharge.



Integrating spatio-temporal Measurments and environmental Modelling with a low cost hydro-climate Sensor Network for Real-Time Measurements

The project aims to model how much rainwater enters the groundwater across New Zealand. Rainwater which drains through the soil and recharges the groundwater is known as rainfall recharge.



Satellite Evapotranspiration for New Zealand

To better understand hydrological processes relating to groundwater, better estimates of all variables in the hydrologic cycle need to be made, including uncertainty estimates. One of the most elusive variables is evapotranspiration



Visualization of 3D Hydrogeological Data in the Web

We present an open and free to use web-based (platform independent) framework to enable retrieval, exploration and visualisation of hydro-climate time series data as well as three- dimensional geological information via a web browser.



Unififed hydro-climate Data Search across New Zealand

Acquisition of relevant and useful data for hydrological, meteorological or hydrogeological assessments and research projects in New Zealand's regions is primarily based on personal communication and reliance on the knowledge of domain specialists. To support the task of identification and subsequently retrieval of available datasets for an area of interest, a new unified method for metadata and data search in New Zealand for hydro-climate and geo-scientific datasets is presented.



A Māori–English thesaurus for a New Zealand groundwater resources portal

Iwi/Māori have a well-recognised relationship with the natural environment which spans many centuries and is the result of interaction and adaptation with native flora and fauna of Aotearoa/New Zealand. Integral to this relationship is water which sustains life and is a taonga (treasure) with significant cultural and physical dimension.
