Splash erosion is recognized as the first stage in the process of erosion that results in bombardment of the soil's surface with rain drops. Two basic processes in soil erosion are the dispersion of soil particles by rain drops and the changes caused to the soil's structure, which are then moved by runoff. In this research, the effect of various rainfall intensity (60, 90 and 120 mm/hr) on the ...

[1] Long-term observational data reveal that both the frequency and amount of light rain have decreased in eastern China (EC) for 1956–2005 with high spatial coherency. This is different from the trend of total rainfall observed in EC, which decreases in northern EC and increases in southern EC. To examine the cause of the light rain trends, we analyzed the long-term variability of atmospheric ...

The relationship between cloud and surface rain rate varies significantly from cloud patch to cloud patch. Therefore, a rainfall estimation model characterized by significant transience, heterogeneity, and variability is needed to associate rainfall with the extremely complex and still imperfectly understood precipitating processes to produce higher quality estimates. We have responded to this ...

The objective of this paper is to describe an autoregressive regression framework with respect to metered sewer flow and simultaneous rainfall data series. The main purpose is to produce more reliable estimates for rain derived inflow and infiltration RDII characteristics in a sanitary sewer basin. The discussion is centered at three specific points: 1 a justification for an autoregressive erro...
