| چکیده انگلیسی مقاله |
Splash erosion is the first stage in the formation of other types of water erosion and plays a very important role in starting and continuing the soil degradation processes. Therefore, awareness of rainfall characteristics, as well as the accurate measurement of soil splash particles, is necessary to study its role on soil erosion processes by water. There are different methods and tools to measure splash erosion, each of which may have different results. Therefore, the aim of this study is to compare the statistical indices of the data obtained by different soil splash measurement tools. To achieve the study purposes, the soil splash components were measured by using four known tools including splash cups and splash trays with splashing inwards and outwards, each at three replications on a sandy clay loam soil under rainfall simulated with constant intensity and duration of 60 mm. hr-1 and 15 min, respectively. The results showed that the highest total and net splash rates (26.03 and 12.61 g. m-2 min-1) were observed using the outwards splash cups, while the lowest rates (1.62 and 0.67 g. m-2 min-1) were observed using inwards splash trays, respectively. The results of one-way ANOVA showed significant differences between total and net splash components in four different studied tools at 95% level of confidence. |
