In this work we investigate the performance of various lower-fidelity models of seawater intrusion in coastal aquifer management problems. The variable density model is considered as the high-fidelity model and a pumping optimization framework is applied on a hypothetical coastal aquifer system in order to calculate the optimal pumping rates which are used as a benchmark for the lower... https://www.roneverhart.com/Liftmaster-850lm-Gate-Receiver-Package-With-2-copyright-Remotes/
