Loss of surface soil and soil solute transport induced by soil water erosion are parts of the complexprocess that is controlled by runoff

soil properties

land surface characteristics

land use and many otherfactors.In this study

a soil trench with a certain degree of slope and a certain rate of surface flow was setupin a laboratory to study the effects of different soil bulk densities on solute migration.The results showedthat during the soil erosion process

the rate of solute transport gradually reduced with time

which can bewell described by apower function.The migration of soil solute was affected by both runoff and subsurfaceflow at the same time.Less soil solute was migrated from the soil with greater soil density as described in apower function.
