Abstract. The Vallcebre catchments are located in a middle mountain area of the Pyrenean ranges, built up by sedimentary rocks and loamy soils. vegetation cover is pastures forests Pinus sylvestris, mostly occupying former agricultural terraces. Some relatively small, heavily eroded landscapes (badlands) occur catchments, playing relevant hydrological geomorphic role. Annual precipitation 924 mm potential (reference) evapotranspiration about 700 mm. Rainfall interception represents 24%...
Abstract The suspended sediment response of a small catchment subjected to farmland abandonment and subsequent plant recolonization was studied in relation its hydrological functioning. analysis data over seven‐year period demonstrated that yield greatly influenced by the occurrence intense, low‐frequency events. Greater amounts were exported during spring, when hydrologically more active. Rainfall intensity baseflow at start flood event had strong influence on response, suggesting several...
Abstract Regolith surface characteristics and response were examined over a three‐year period in badland area Mediterranean middle‐mountain zone near Vallcebre (Eastern Pyrenees). Preliminary work carried out this indicated clear seasonal patterns of regolith properties driven by frost heaving winter crusting erosion the rest year. Rainfall simulations performed with small portable nozzle simulator order to study changes runoff generation, rates raindrop effect on bulk density changes. The...
This study investigates the geomorphological dynamics of badland areas in Araguás catchment (0.45 km 2 ) Central Pyrenees. The genesis and development badlands Pyrenees is favoured by presence Eocene marls a markedly seasonal climate. has been monitored since 2004. Analysis weathering processes regolith showed that alternating freeze-thaw wetting-drying cycles are main causes weathering, effectiveness intensity these maximum winter summer. Evolution surfaces related to moisture level...
Abstract The genesis and development of badlands is controlled by bedrock lithology, topography climate. in the Central Spanish Pyrenees favoured presence marls a climate with marked seasonality; combination these factors results active hydrosedimentological processes. aim present work was to study dynamics Pyrenees, focus on temporal spatial patterns dominant weathering area small mountain catchment, we focussed continuous observation number physical parameters that control regolith Samples...
The Vallcebre catchment (Llobregat river head-waters) shows an important variety on land uses and geomorphic environments: forest, pasture, farmed abandoned agricultural terraces, badlands. Three nested catchments (Cal Rodó, Ca L'Isard Can Vila) were equipped to measure hydrological sedimentological yield from different conditions. There was also set a raingauge net two weather stations in the basin. Badland areas, that occur only Cal Rodó l'Isard catchments, are relatively small but very...
Abstract The effects of afforestation on water resources are still controversial. aim this paper is to (i) analyse the hydrological response an afforested area in Central Pyrenees and (ii) compare with observed a natural undisturbed forest. Araguás catchment was cultivated until 1950s, then pines effort control active degradation processes. variable complex, because discharge generated by combination distinct runoff showed that produced moderate peak discharges, stormflows recession limbs,...
Relationships between discharge and suspended sediment are very complex in most Mediterranean catchments. In the case of Arnás catchment (Central Spanish Pyrenees), with a long history human activity, main factors that explain variability concentration (SCC) during floods peak flow intensity precipitation. A cluster analysis distinguishes four types according to different characteristics precipitation, discharge, transport antecedent moisture conditions. G1 G2 occur under dry conditions...
This article considers the effects of forests on hydrology a Mediterranean mountain area. Variations climate factors, discharge, interception, and water table depth in San Salvador forested experimental catchment Central Spanish Pyrenees were studied results compared with those from two deforested catchments. The hydrological response had following properties: 1) it both smaller peak flows low than catchments; 2) most rainstorm events produced almost no discharge response; 3) intensity...
Vegetation expansion following farmland abandonment is a complex process that depends on multiple natural and human-induced factors, resulting in differences the evolution of land cover former cultivated fields, with various environmental implications. To assess complexity hydrogeomorphological consequences abandonment, Instituto Pirenaico de Ecología (CSIC) University La Rioja monitored three small catchments, representative different post scenarios, Pyrenees Iberian Range respectively. In...
Abstract In this study, we investigated rainfall, run‐off, and sediment transport dynamics (414 run‐off events 231 with information) of a humid mountain badland area—the Araguás catchment (Central Pyrenees, Spain)—from October 2005 to September 2016. Use long‐term database allows characterization the hydrological response, which consist low‐magnitude/high‐frequency high‐magnitude/low‐frequency events, identification seasonal rainfall‐run‐off thresholds. Our results indicate that catchment,...
