Impact of Rainfall Microstructure on Erosivity and Splash Soil Erosion Under Simulated Rainfall

摘要: Rainfall represents the major driver of soil detachment in erosion processes. The potential rainfall to detach has been defined as erosivity. relationship between intensity and drop size distribution (DSD) controls various characteristics including erosivity (Abd Elbasit et al., 2010). differs due geographical location under natural (Hudson 1965; Wischmeier Smith, 1978; Zanchi Torri, 1980; Van Dijk 2002) type configuration simulators simulated (Hall, 1970; Olayemi Yadav, 1983; Auerswald 1992; Salles Poesen, 2000). role microstructure on determination attracted several researchers past. However, our understanding this subject is still limited lack equipments that are able measure parameters ultimately kinetic energy. Several indices have suggested quantify Generally, suitable index must include mass velocity variables for raindrop power determination. described by Epema Riezebos, 1983 follows:
