Supporting Data for: Grid-Converged Reference Solutions for the Nonlinear Boussinesq Equation in Sloping Aquifers (Water Resources Research, 2026)

This dataset supports the manuscript titled "Grid-Converged Reference Solutions for the Nonlinear Boussinesq Equation in Sloping Aquifers: A Reassessment of the Classical Falling Water-Table Problem" submitted to Water Resources Research. The dataset contains 6 tables and 1 figure that present numerical reference solutions for the nonlinear Boussinesq equation in sloping aquifers. These solutions are obtained using grid-converged numerical methods and reassess the classical falling water-table problem.
