About This Event
This webinar is 90 minutes.
This webinar is complimentary to non-North American audiences in the CAS.
Since water resources are critical for human survival, even short-term disruptions in the supply of water can have potentially devastating consequences, including adverse impacts on financial security systems. The seminar aims to provide an overview of the assumptions, methods, limitation and regional scale finding results associated with national scale assessment of climate change impact on hydrological regimes in the New Zealand context.
This was carried out by coupling IPCC 5th climate projection ensemble for New Zealand with a-priori parametrised hydrological model.
As part of the seminar, I will use case studies to illustrate some of the challenges associated with the use and interpretation of those datasets to inform water resource and hydrological extreme investigations. I will provide key messages on expected differences associated with the use IPCC 6th Assessment (on-going investigation)
Key Messages
- Climate change impact will affect differently hydrological regimes across New Zealand depending on Representative Concentration Pathway (warming scenarios).
- Change significant around 2040 across North Island (depending on hydrological characteristic)
- Use of current climate projection is limited to represent hydrological extremes
- site specific analysis different from regional/sub regional scale analysis
This webinar is complimentary to non-North American audiences who are part of the CAS and the CIA. The webinar will be conducted over GotoWebinar. Please make sure to test your system.
Christian Zammit
National Institute of Water and Atmospheric Research
Christian is a hydrologist with more than 15 years of experience in research, regional government and environmental consulting in New Zealand and Australia. Over that time, he has undertaken a variety of projects focused on delivering hydrological information (combining hydrological observations and hydrological model outputs). Over the past 10 years, Christian has specialised in developing climate change impact assessment on flow regimes from catchment specific analysis to national scale assessment. Those helped to foster his understanding on how science is used as part of policy establishment and operational decision making across central and regional government environment and across industry sectors. A key aspect of Christian’s expertise is to incorporate technical information into decision-making process and to tailor hydrological investigations to decision maker needs.
