Dune sand was subjected to a range of rain intensities (6.5–64.5 mm/hr) using a rainfall simulator. A linear relationship was found between the side splash erosion and the kinetic energy of the rainfall.
Different rates of chemicals, used to stabilize the sand against the raindrop impact, were sprayed on the surface or incorporated with the sand.
Polyvinyl acetate, polyacryl amide (with cross-linker) and an asphalt emulsion, applied at optimal rates, diminished appreciably the side splash erosion for dune sand.
