High porosity is not necessarily better in all cases. While high porosity allows for greater permeability and more space for fluids to flow through, it can also lead to reduced strength and stability in geotechnical materials. For example, in certain soil or rock formations, high porosity can contribute to increased risk of subsidence, settlement, or slope instability. Therefore, the suitability of high porosity depends on the specific application and engineering requirements of the project.«Energies free full-text a simple fractal-based model for soil-water characteristic curves incorporating effects of initial void ratios»
