MATLAB code for: Delay of Flood Formation by Sponge-Like Porous Bodies on Unsaturated Soil: A Richards' Equation Model

MATLAB code accompanying the manuscript “Delay of Flood Formation by Sponge-Like Porous Bodies on Unsaturated Soil: A Richards’ Equation Model” (Frontiers in Water). The scripts solve the one-dimensional Richards equation in a soil column with a sponge-like porous body (SPB) at the surface, using a Gardner (analytical, semi-analytical and numerical) and a Brooks–Corey (numerical) hydraulic model, and reproduce the flood formation times, figures and tables of the paper, including the numerical verification and the sensitivity to the Gardner parameter α.
