  • This paper presents the results of rill experiments accomplished in Andalusia (at Negratin, Freila, Salada and Belerda) in September 2008 using a novel experimental set up. Rill cross sections, slope values, flow velocities and sediment
  • concentrations were measured and these values were used to calculate sediment detachment and transport. In rill experiments, 4 different natural rills were flooded with the same experimental setup. Several processes like transport of loose material, erosion, bank
  • failure and knickpoint retreat and the runoff effectiveness showed different and variable intensities. The results suggest that the existing soil erosion equations based on shear forces exerted by the flowing water are not able to describe rill erosion
  • processes satisfactory. Too many different processes with a high spatial and temporal variability are responsible for rill development.

  • The objective of this paper is to investigate the relation between bed roughness and channel width using field evidence from rill and small gully channels using the extended river geometry equations for rills and gullies, with the aim to identify
  • a possible unification of the processes of channel formation. The validity of this approach is tested against channel data from Mars. Finally, an equation predicting bed roughness and based on stream power is developed and compared with measured rill

  • , this study aims (1) to provide an overview of both R and SL rates by interrill and rill erosion, measured at the plot scale; (2) to assess the variability in both R and SL rates for different land uses and different climatic regions in the study area; and (3
