Hydrology, surface runoff and groundwater recharge research

Summary of research

Climate change is affecting the water cycle, with higher temperatures and more variable rainfall changing how much water is available as surface water and groundwater. These reports and data were published by the NSW Government in 2015, and can help analysts and decision makers understand how NSW’s water resources are affected by climate change, and make better informed planning and management decisions.
