Mechanics of interrill erosion with wind-driven rain
The vector physics of wind-driven rain (WDR) differs from that of wind-free rain, and the interrill soil detachment equations in the Water Erosion Prediction Project (WEPP) model were not originally developed to deal with this phenomenon. This paper
with an experimental setup to study different raindrop impact velocity vectors. Synchronized wind and rain simulations with different wind velocities were applied to a test surface placed on windward and leeward slopes. The results suggested that along with the fall
Soil detachment caused by divided rain power from raindrop parts splashed downward on a sloping surface
In modelling interrill erosion caused by raindrops splashed on the soil surface, the parameters most frequently considered are the kinetic energy of the raindrops, the rain power and the rainfall intensity. This paper presents arguments supporting
of dyed sediment by wind, runoff and rain splash in 5 × 5 cm areas on shrub-mounds, placed under the canopy and on mound margins, and on the biological soil crust-covered intershrub space. As experimental treatments, they used artificial rain covers

were tested with 4 different slopes and subjected to 5 different rainfall intensities. It is showed that : Vegetation cover yields a greater soil moisture increase than do bare land; Water storage initially grows and then reduces as the rain intensity
rise; Water storage increase firstly rises but then falls as the slope grew from 8.8 to 36.4%; IRC rise with growing coverage and falling rain intensity, angle, initial moisture.

A set of rainfall simulations were carried out on bare loess-burden soil with different antecedent soil moisture content. All treatments were compared with controls protected from rain drop impact using a fine-meshed geotextile. As expected, runoff

that sediment yields were related to rain intensity, time since fire, and ground cover. Wood strand mulch reduced sediment yields for up to 4 post-fire years. Straw mulch reduced first post-fire year sediment yields at 2 of 4 fires. Hydromulch did not reduce
