Abstract: Laboratory investigation of rainsplash erosion on Malan Loess has been conducted based on a multivariate orthogonal design.Five factors including rainfall intensity (I),cover density (V),rainfall duration (T),antecedent soil moisture content (C),and slope angle (A)were considered.In total,three replicates of 27 sets of experiments,each representating a different combination of the factors selected,were conducted.Regression equations using rainsplash detachment and rainsplash transport as dependent variables and derivatives of the five selected factors as independent variables were computed:What is significant is the inclusion of six and four interaction terms in the equation for splash detachmet Y and splash transport Z respectively.The analysis of results obtained from two equations shows that the interaction effects among some of the controlling factors of rainsplash erosion are of paramount importance.
