Effect of Climate Change on River Flows and Groundwater Recharge, A Practical Methodology: Recharge and Groundwater Level Impact Assessment
This report provides tools and guidance on how to estimate changes in recharge and regional groundwater levels based on changes in precipitation and potential evaporation. The report provides a framework for assessing the impacts of climate change on groundwater recharge using three approaches with varying levels of complexity, and provides worked examples of these methods.
In summary these approaches are:
GR1 - Based on a relationship between antecedent precipitation conditions and minimum groundwater levels at a particular location.
GR2 - A spreadsheet model which undertakes lumped calculations of recharge and groundwater level.
GR3 - Utilising existing regional groundwater models.
The methods presented here should enable companies to identify appropriate analytical approaches to assess the impact of climate change. These approaches consider uncertainty and can be used for the PR09 Draft Water Resources Plans.
