Incorporating Crusting Processes in Erosion Models

摘要: In most soils, surface crusting strongly influences the infiltration and erosion processes, so there is a need to include in modelling. The processes involved crusting, however, are extremely dynamic crust characteristics often difficult measure. Significant progress has been made describing formation. Aggregate breakdown displacement reorganisation of detached soil units give rise two general categories crusts: structural depositional. Modelling into these crusts led development equations varying complexity, ranging from simple empirical numerical solutions Richards equation. Obtaining parameters for more mechanistic approaches remains challenge, be evaluated under field conditions where have high spatial variability. For modelling, many common implicitly present some models. Further research should consider potential estimating quantitative needed modelling descriptive studies micromorphology.
