Climate Change Impacts on New Zealand’s Hydrological Regimes

Climate Change Impacts on New Zealand’s Hydrological Regimes

Join our Sustainability Interest Group for a session exploring the impacts of climate change on New Zealand’s water systems. With water resources being vital to human survival, even short-term disruptions can have serious consequences.

In this session, we’ll present an overview of the assumptions, methods, limitations, and regional-scale findings from a national assessment of climate change impacts on hydrological regimes in New Zealand. This work integrates the IPCC 5th Climate Projection Ensemble ensemble for New Zealand with an a-priori with a pre-parameterised hydrological model to assess future water scenarios.

Highlights include:

• Case studies with some of the challenges associated with the use and interpretation of the datasets to inform water resource and hydrological extreme investigations

• Insights into water resource planning and hydrological extremes

• A review on expected differences associated with the use of IPCC 6th Assessment results.

📅 Date: Tuesday 30th September
🕔 Time: 5:00 PM – 6:00 PM
📍 Location: Online

Don’t miss this opportunity to gain valuable insight into the future of water in New Zealand under a changing climate.

About our Speaker

Dr Christian Zammit is a hydrologist with a MSc in small scale hydrology and PhD in Soil Physics (University Joseph Fourier- France). He works for NIWA, and his research interests include developing improved methods for making hydrological predictions in ungauged catchments, understanding the spatial variability in hydrological response through measurement, conceptualisation and modelling of surface water and groundwater flow across landscape and temporal scales, and uncertainty quantification in water resource and weather-related hazard management.
