InfiAsper: a rainfall simulator with varying precipitation intensity to assess soil erosion

Abstract

Research involving the use of rain simulators dates to 1930. Since then, the evolution of this equipment has made it increasingly accessible, practical, and accurate. Its applications include the assessment of the impacts of water erosion on soil degradation as a function of land use and occupation and the rate of water infiltration into the soil. The reproduction of the rainfall pattern by varying the intensity of precipitation is one of the main limitations of the use of simulators. However, the recent modification in InfiAsper (Macedo et al., 2021) allows instantaneous varying the intensity of rainfall application and provides high uniformity in rainfall of different patterns.
