  • The aim of this paper is to quantify the amount of surface water redistribution in 3 areas in Spain (Murcia, Valencia, Albacete) having different climatological characteristics, for a fine spatial scale and temporal scales of 1 yr and 10 yr
  • . Rainfall simulations experiments were carried out to determine runoff and infiltration characteristics of the bare and vegetated zones. The largest amount of redistribution during these events is found for areas having an intermediate rainfall regime

  • Vegetation arcs are near parallel bands of denser vegetation aligned perpendicular to slope and separated by barer inter-arc zones. These patterns occur in arid and semi-arid areas of gentle gradient. Similar, but much smaller scale patterns, here

  • and the underlying soil chemical properties; that bare areas have a relatively larger soluble salt concentration compared to the vegetated areas. A model that explains this distribution, and incorporates vegetation, microtopographic and infiltration differences

  • the agricultural fields, the main floral biomass and the areas which have the highest grazing value, are limited to narrow valleys filled with redeposited loessial sediments. The headcut migration and gully development in the region were studied between 1990
  • The aim of this study is to use global positioning system (GPS) to measure the morphology of gullies in a small catchment near Suide, Shaanxi Province, China. There are 3 main gully types in the study area : bank gullies, floor gullies, and hill
  • slope gullies, and this study mainly focuses on the hill slope gullies. The short-term erosion rates of hill slope gullies, slope-area relationships, and thresholds of hill slope gully initiation are investigated.

  • This paper aims to calculate water balance of an entire tiger bush unit, including bare and vegetated areas, to validate a rain redistribution hypothesis. They monitored measurements of runoff and soil moisture content in each zone composing a tiger

  • to improve the knowledge of the spatial variability of infiltration in black marl areas and to compare different field and data analysis methods.
  • Linear erosion (LE), including rilling and gullying, has been identified as the major problem for sustainable agriculture in steepland areas. The aim of this study is to quantify the spatial and temporal variations of linear erosion at the catchment
