报告摘要：The water table fluctuation (WTF) method is the most widely used approach to the estimation of recharge. It relies on empirical extrapolation of water table recession,and yet,it has not been tested previously in a systematic way to examine the accuracy of its main assumptions. This study uses numerical modelling, an analytical solution, and a field case to compare the various alternative approaches to WTF-based recharge estimation. The results show a systemic under-estimation of recharge that can be minimised by adopting specific techniques, such as depth-dependent specific yield, a fixed timestep, and careful evaluation of water table recession to obtain a Master Recession Curve. Their application to a complex field site in North Queensland shows strong correlation to an independent assessment of recharge using 1D numerical simulation.

报告人简介：Adrian Werner is a Professor of Hydrogeology at Flinders University,a founding member of the National Centre for Groundwater Research and Training,a founding member and Chair of the Asia-Pacific Coastal Aquifer Management Meeting,a Fellow of Engineers Australia,and a prior Future Fellow of the Australian Research Council. He is a previous recipient of a CAS PIFI grant through which he has worked closely with NIGLAS. He is passionate about hydrogeological research that has real-world benefits for those who need it the most. His presentation today uses multiple techniques to investigate the movements of saline groundwater within a high-value groundwater system within a coastal agricultural region of northern Queensland,Australia – and he hopes to encourage some of the many young,talented researchers here today to consider this exciting and challenging field of groundwater research for their future studies.
