Rainfall simulators have been used for erosion research for more than 50 years now. These
are widely used in agricultural soils to assess the infiltration capacity and porosity of soils,
and hence learn lessons on the potential of plant roots to penetrate those soils. Recently,
rainfall simulators have been very useful to investigate soils detachment by both the
raindrops kinetic energy and the subsequent flow shear stress. This has led to notable
advances in the understanding of the failure of infrastructures such as unpaved roads due to …
