Climate change will impact hydrology in complex ways under a Representative Concentration Pathways (RCP) of 8.5. An RCP of 8.5 is the most extreme value with greenhouse gases continue to rise throughout the 2000’s.
The dataset - What is it?
The six key hydrological indicators predicted are snowpack, plant canopy, rooting zone, shallow subsurface, lakes and rivers. For New Zealand regions Low Flows, Mean discharge, Flood Flows, Flow Reliability and summer moisture deficit are shown as positive or negative.
Why it's important
This is an example of the extreme hydrological impacts of climate change as this is the highest RCP or level of greenhouse gases. This level of hydrological change will have a large impact on land use and management. Mitigation will hopefully see an RCP of 8.5 never occur as adaption will be very difficult.
