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
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.

This paper evaluates the use of the model both for single event and yearly soil loss estimations using erosion plot data from Nicaragua and data obtained through rainfall simulator experiments in Costa Rica and Mexico.
The aim of this study was to specify the wind and rainfall characteristics of the developed Portable Wind and Rainfall Simulator (PWRS) and to evaluate if its simulation quality and reproducibility is adequate for comparative soil erosion studies
The European Soil Erosion Model (EUROSEM) is a dynamic distributed model, able to simulate sediment transport, erosion and deposition over the land surface by rill and interill processes in single storms for both individual fields and small
