Abstract

Understanding groundwater recharge is essential for sustainable management of water resources and modelling fluid and contaminant transport within the subsurface. Over the past, a number of methods have been developed to estimate groundwater recharge because it cannot be measured directly. However, it is still unclear what are the primary factors controlling groundwater recharge estimation at the daily and monthly temporal scales. In this paper, we examine multiple correlations between the possible controlling factors and their corresponding daily and monthly groundwater recharge estimates using the water table fluctuation (WTF) method within the Tomago sand beds, New South Wales, to identify the primary factors controlling recharge. The results show that the most important factor controlling the daily and monthly WTF recharge is rainfall, rather than the depth to the water table or groundwater level, although both of them are important parameters in the WTF groundwater recharge estimation.
