Concentrated flow erosion in Mediterranean cultivated areas is considered a major process of land degradation. Rills and ephemeral gullies in a 6.4 ha olive orchard catchment located in an intensive commercial farm, which could represent a common degradation scenario in hilly areas, were measured and compared with the sediment loads at the outlet. Four GPS survey campaigns were carried out between March 2009 and March 2014, for periods with cumulative precipitation ranging between 728 and 121 mm. Chopped pruning residues were kept on the lanes during campaigns 2–4, whereas a grass cover crop was seeded in campaign 4. Rainfall, runoff and sediment loads were measured in a flume gauge station at the catchment outlet.

西班牙一个小橄榄树小流域的小溪和临时沟壑侵蚀：管理措施与保护措施之间的相互作用

地中海耕种区集中的水流侵蚀被认为是土地退化的主要过程。测量了位于集约化商业农场的6.4公顷橄榄园集水区中的小坑和临时沟壑，这可能代表了丘陵地区常见的退化情况，并将其与出口处的泥沙量进行了比较。在2009年3月至2014年3月之间进行了四次GPS调查，累积降水量在728至121 mm之间。在活动2-4中，修剪过的修剪残留物保留在车道上，而在活动4中播种了草皮作物。在集水区出口处的水槽计量站测量了降雨，径流和泥沙量。
