  • The objectives of this study were to anlyse the effect of slope angle on interrill erosion for different plot sizes and to identify possible detachment and transport processes involved in the interactions between slope, rain characteristics and plot
  • size. Runoff rate, flow velocity and sediment delivery were measured in the field under different slopes and plot sizes for both natural and simulated rainfall. Rain-impacted flow conditions were also compared to flow conditions only.

  • Daily rainfall amounts were classified into dry or wet events to arrive at sequences of dry and wet spells at six rainfall stations in Zambia over a 19-year period from 1980 to 1998. In the resulting patterns, the total number of non-rain events per
