  • This paper discusses the effects of water quality on the hydrological and erosion response of non-saline, non-sodic soils during simulated rain experiments. Two soils, a well-aggregated clay-rich soil developed on marine silty clay deposits
  • and a soil developed on silt loam, were selected and subjected to a series of simulated rainstorms using demineralized water and tap water. The hydrological response (infiltration, runoff), the physical degradation (soil surface roughness change and top-soil

  • Ephemeral gully erosion is a significant water erosion process, accounting for 50% of the total sediment production in agricultural catchments in the Belgian loess belt. Therefore the aim of this study is to address 4 basic questions : what
  • are the ephemeral gully characteristics ? why is ephemeral gully erosion an important water erosion process ? when/where will ephemeral gullies occur ? how do ephemeral gullies evolve over time ?
