Behavior of Coastal Amagmatic Geothermal Systems: Thermal–Hydraulic Modeling Insights from La Jolla Beach, Baja California, Mexico

This dataset contains the input files used for all numerical simulations presented in the manuscript “Behavior of Coastal Amagmatic Geothermal Systems: Thermal–Hydraulic Modeling Insights from La Jolla Beach, Baja California, Mexico.” The simulations model heat and fluid flow in coastal amagmatic geothermal systems using 3-D coupled thermal–hydraulic models. The input files here allow other researchers to reproduce or extend the simulations exactly as described in the paper. This publication is submmited to the Journal of Geophysical Research. File naming convention Each file name includes the simulation case, the fault width, and the fault permeability.The structure is: Case <number>[_Tracer50yr | _Tracer1Ma]_F <width> m k_<permeability>_<filetype> Case <number> — main simulation scenario (0, 1, 2, or 3). _Tracer50yr — tracer injected after 50 years (used in Case 2). _Tracer1Ma — long-term evolution run of 1 million years (used in Case 2). F <width> m — fault width in meters (e.g., 15 m, 45 m, or 105 m). k_<permeability> — fault permeability in square meters (e.g., 3E-14m2 or 1.1E-14m2). <filetype> — file type, one of: flow.inp – simulation control file INCON – initial conditions MESH – computational grid chemical.inp – tracer/solute chemistry setup solute.inp – tracer definition and injection parameters tk-slt.h06es.dat – thermodynamic/solute database used for tracer runs Simulation cases Case 0, 1, and 3: Base simulations for different fault widths (15, 45, 105 m) and permeabilities.Each case includes three files: flow.inp, INCON, and MESH. Case 2: Includes both standard and tracer simulations: Tracer at 50 years: files include _Tracer50yr_ in the name. Long-term (1 Ma) run: files include _Tracer1Ma_ in the name.Each tracer case includes additional files:chemical.inp, solute.inp, and the database file tk-slt.h06es.dat. Files follow the standard structure used in TOUGH/TOUGHREACT simulations for coupled flow and heat transport. Example To reproduce the Case 2 tracer simulation with a 105-m-wide fault and permeability of 1.1×10⁻¹⁴ m², use: Case 2_Tracer50yr_F 105 m k_1.1E-14m2_flow.inp Case 2_Tracer50yr_F 105 m k_1.1E-14m2_INCON Case 2_Tracer50yr_F 105 m k_1.1E-14m2_MESH Case 2_Tracer50yr_F 105 m k_1.1E-14m2_chemical.inp Case 2_Tracer50yr_F 105 m k_1.1E-14m2_solute.inp tk-slt.h06es.dat
