Analytical solutions and SEAWAT model files for optimizing saltwater extraction and freshwater-lens protection in saline riparian aquifers

This dataset contains the analytical Python scripts, SEAWAT v4 model input files, final concentration and hydraulic-head arrays, mass-balance outputs, and selected figures supporting the manuscript “Analytical solutions for optimizing saltwater extraction and freshwater lens protection in saline riparian aquifers.” The numerical material includes nine SEAWAT cases representing four flux-controlled and head-controlled aquifer configurations. A README file describes the package structure, model scenarios, pumping-rate convention, software requirements, and excluded regenerable binary outputs.
