Abstract

One goal of this study was to assess the suitability of a novel field hybrid rainfall simulator (FH simulator) that combines characteristics of a spray nozzle and a drop former rain simulator (DF) for erosion research. Two soils with different textures were irrigated. A second goal of this study was to quantify the influence of vegetation and soil structure stability on soil erosion and runoff in a subalpine grassland area. The kinetic energy, drop size, triggered runoff and sediment yield 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
