In this study, changes in the structure and physical properties of the surface crust of an Andisol, especially during the rainfall, were measured by using a rainfall simulator, and effects of surface crust on hydrology and soil erodibility
This paper reports a set of field rainfall simulation experiments conducted in the hilly loess region, North China designed to investigate the effects of surface crusting and slope gradient on soil and water losses. Specifically, the objectives
are 1) to determine the effects of antecedent crusting and sealing on soil and water losses under simulated rainfall; and 2) to establish the influence of slope gradient on soil and water losses under crusted and uncrusted conditions.
Antecedent soil moisture (ASM) has a high variability during the year. Its influence on the structural breakdown of the soil surface and on the erosion process was examined with simulated rainfall on a loessial soil at seebed stage. The objective

cylinders and subjected to simulated rainfall. The results suggest that these ultisols are less stable than the midwestern alfisols and mollisols, but generally form more permeable seals, perhaps due to the higher sand content.
Three soils representing major land-use resource areas from the humid eastern USA with mineralogy dominated by mica/kaolinite and low sodium contents were studied to determine their infiltration behavior with time during rainfall and interrill
