  • Effect of bed topography on soil aggregates transport by rill flow
  • The aim of this work is to investigate the ability of the flow to transport soil aggregates along a real rill at discharges below the formative discharge; and to analyse the influence of the rill pools on this transport process. This subject
  • is an important issue as the transport capacity of rills is highly relevant for phenomena such as soil exportation from fields, catchment-scale sediment redistribution, and sedimentation in streams.
  • Hydraulics of interrill overland flow on rough, bare soil surfaces
  • Model ; Overland flow ; Rill wash ; Roughness ; Slope
  • on detailed surface roughness data. Roughness profiles perpendicular to the flow are used to calculate the wet cross-sectional area and hydraulic radius given a certain water level. The algorithm of Savat is then applied to calculate the hydraulic resistance
  • . The model is able to predict flow velocities reasonably well from discharge and roughness data only.
  • Concentrated flow erosion rates as affected by rock fragment cover and initial soil moisture content
  • Concentrated flow experiments using a small hydraulic flume and a constant flow discharge and bed slope have been conducted in order to investigate the effects of rock fragment cover (Rc) on sediment yield for an initially wet and an initially air
  • The objectives of this study were to test the hypothesis of Gimenéz and Govers (2001) by investigating whether rill flow is indeed characterized by an alternation of sub- and superficial flow reaches and, if so, how these variations are related
  • to rill bed morphology. In order to achieve these objectives, detailed data on longitudinal variations in rill flow hydraulics were collected using an miniaturized acoustic Doppler velocimeter (mADV)
  • An automated salt-tracing gauge for flow-velocity measurement
  • This article introduces the SVG (salt-velocity gauge), a novel automated technique for measuring flow velocity by means of salt tracing. Two implementations of the SVG technique are described : an outdoors simulated rainfall experiment in Senegal
  • The main aim of this study was to develop an approach to predict soil detachment by rill flow in the presence of freshly incorporated vegetation residue that is compatible with current understanding of rill hydraulics and requires no additional
  • information on rill geometry. Laboratory experiments were carried out. The data are presented and analyzed. An approach to calculate the erosivity of rill flow on surfaces with fresh vegetation residue is proposed. Finally, this new procedure is evaluated
  • This study focuses on problems related to estimating the exact exported suspended sediment quantity and quality from flow-proportional samples taken at a fixed height at the outlet of a small, agricultural catchment in central Belgium
