  • Hydraulic conditions for rill incision under simulated rainfall : a laboratory experiment
  • Downcutting;Incision ; Experimentation ; Gully erosion ; Hydrodynamics ; Rainfall ; Rill wash;Runoff ; Roughness ; Sediment load ; Sedimentary ; Simulated rainfall ; Soil erosion
  • A series of controlled laboratory experiments were conducted in order to obtain precise data on the hydraulic and sediment transport conditions during rill formation.

  • A relationship betwen discharge, flow velocity and flow area in rills is established using data from four field and laboratory studies. The proposed relationship may be used to improve performance of deterministic flow routing models when applied
  • to rilled catchments. Furthermore, it allows the calculation of unit stream power, which has been shown to be related to the transporting capacity of overland fow, in terms of slope and discharge.

  • factors are calculated for the top layer of soils where rill and interrill erosion occur. The K-values generated by each model are then compared throughout the range of soil types varying erodibility. For both models average K-values per unit area
