Transport modeling and multivariate adaptive regression splines for evaluating performance of ASR systems in freshwater aquifers

摘要

Highlights?REN is the proportion of the injected water that the same ASR wells can recover.?The study estimates REN in freshwater aquifers using a transport model.?The study details the process to prepare a reliable refined flow model.?The study reports the first application of MARS regression to manage an ASR system.?Results show the importance of having preexisting water rights for high RENs (～100%).AbstractThe study presents a procedure using solute transport and statistical models to evaluate the performance of aquifer storage and recovery (ASR) systems designed to earn additional water rights in freshwater aquifers. The recovery effectiveness (REN) index quantifies the performance of these ASR systems. REN is the proportion of the injected water that the same ASR well can recapture during subsequent extracti
