NZ water model

The purpose of the water-age model is to represent water exchange between land, surface-water bodies and aquifers, by coupling the surface water and groundwater models.

This task aims to improve and enhance the accuracy of surface hydrological model discharge predictions, at both catchment and regional scales.

The role of the NZWaM groundwater model is to improve surface water model simulations, by estimating groundwater storages and groundwater fluxes.

The purpose of the Hydro-Geofabric task is to gather, harmonise and augment existing multi-source spatial datasets to form a framework tailored for hydrological modelling.

The purpose of the benchmarking task is to develop and implement a state-of-the-art operational method (that can be applied at national scale) to test hydrological models in New Zealand

The NZWaM – Hydro project is led by NIWA but all work is conducted in collaboration with our project partners.

Bringing together leading scientific organisations and regional councils, this project aims to develop 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 through New Zealand catchments.
