The response of idealized aquifer/river systems to climate change

Abstract

A study of the effect of changes in climate on aquifer storage and river recharge using a simple model of an idealized aquifer/river system shows the combined influence of aquifer properties and climate change scenario on the system response. The study shows that changes in the seasonal distribution of recharge may have a critical effect on low flows in rivers supported by baseflow. However, rivers supported by slowly responding aquifers may show a considerable delay in response to climate change allowing an opportunity for water resources planning over an extended period.
