Evaluation and application of a portable rainfall simulator on subalpine grassland

of both rain simulators were comparable, but kinetic energy and drop size differed for both simulators from natural rain. The results demonstrate that vegetation cover plays a crucial role in alpine soils for soil structure stability and erosion.

Splash erosion potential under tree canopies in subtropical SE China

Sand-filled splash cups were used to study the erosivity of rainfall and throughfall in the humid subtropics of southeast China. The results showed that the splash cup measurements yielded precise and reproducible results both under open field

Interrill erosion of carbon and phosphorus from conventionally and organically farmed Devon silt soils

intensity and kinetic energy to determine the effects on the P and C enrichment in interrill sediment. Interrill soil erodibility was lower on the OS, irrespective of rainfall intensity. Sediment from both soils showed a significant enrichment in P and C

Estimating changes in effective values of surface detention, depression storage and friction factor at the interrill scale, using a cheap and fast method to mold the soil surface micro-topography

with time and precipitation, it is necessary to isolate the impact of the micro-topography from the infiltration. Therefore the AA. developed a fast and cheap in-situ molding method that combines alginate, plaster and lacquer. Both the surface of a specific
