Rill erosion plays an important role in soil erosion, and studying this process can provide a basis for controlling loss on sloping farmland. The objectives of study were to observe runoff sediment transport processes during two continuous intermittent natural rainfall events monitor the changing morphological characteristics rills within standard plot bare (20 m length, 5 width, slope 10°) at ...

Flow velocity is one of the most important hydrodynamic variables for both channelized (rill and gullies) interrill erosive phenomena. The dye tracer technique to measure surface flow Vs based on measurement travel time a needed cover known distance. measured must be corrected obtain mean V using factor αv = V/Vs which generally empirically deduced. can influenced by method applied dye-tracer v...

In this paper, for the first time, effect of longitudinal profile shape rill (uniform, concave, and convex) on flow resistance law was studied. The part paper is based a theoretical equation to estimate Darcy–Weisbach friction factor f, deduced from power velocity distribution measurements performed plot. At first, Γ parameter calibrated using all available measurements. Then an analysis hydrau...

Soil erosion results from an interaction of several parameters, which vary in space and time. Awareness ofenvironmental changes and their impact on the intensity and spatial pattern of water erosion can effectively help inrecognition of erosional reactions versus the affecting factors. The aim of this paper is to describe the development ofa methodology based on present knowledge and available ...
