We studied the effect of pore‐water pressure and particle‐size distributions on the amount of sand splash and on the instantaneous pressure changes within a packed sand core caused by single water drops falling on the surface. Both splash amounts and pore‐water pressure changes were affected by particle size, pore‐water pressure before drop impact, and by the direction of approach to the pore‐water pressure equilibrium. Pore‐water pressure increases from falling water drops were generally greater when equilibrium pressures were approached directly than when they were approached from minimum pressure. Sand splash was also generally greater when equilibrium pressure was approached directly.
