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 and SEAWAT v4 model files supporting the manuscript “Analytical solutions for optimizing saltwater extraction and freshwater lens protection in saline riparian aquifers.” The analytical material includes scripts and generated figures for noncritical and critical pumping. The numerical material comprises four half-domain SEAWAT cases representing Scenarios S1–S4. In each case, the model-input extraction rate is −50 m3/day, corresponding to a full-domain rate of 100 m3/day. Each scenario folder contains the Python model script, SEAWAT name and package input files, final concentration and hydraulic-head arrays, the MT3D mass-balance file, and the SEAWAT list file. Simulation-result PNG files and large regenerable binary outputs (.cbc, .hds, and MT3D001.UCN) are excluded. The README describes the package structure, pumping-rate convention, software requirements, and procedures for running the supplied SEAWAT input files or re-enabling execution through FloPy.
