“…These massive erosion processes introduce large amounts of sediments into the channel and change the channel morphology (Simon and Darby, 2002;Kondolf et al, 2002;Stott and Mount, 2004). Several examples can be seen around Europe (Keesstra et al, 2005;Beck et al, 2009;Quiñonero-Rubio et al, 2016) and in China, where the success of the ecological restoration of the Yellow river resulted in a severe deficit of water and sediment (Fu et al, 2017). Such effects could be taken into account and prevented in specific cases, by adapting the type and quantity of the restoration or hydrological control works.…”

“…Especialmente notable fue el desarrollo de la cobertura forestal con un cambio del 245% pasando a ocupar el 49% de la superficie de la cuenca. Esta tendencia hacia una mayor extensión del bosque, y como respuesta, los cambios en las morfologías fluviales, sigue el patrón descrito en cuencas pirenaicas (Beguería et al, 2006), en otras áreas más húmedas del SE español (Boix-Fayos et al, 2007;Quiñonero-Rubio et al, 2016;Pérez-Cutillas et al, 2018), en otras cuencas europeas (Keestra et al, 2005, Beck et al, 2009 y responde al proceso de reverdecimiento de los sistemas montañosos del Mediterráneo Norte, como respuesta a políticas de restauración y cambios socioeconómicos (García-Ruiz et al, 2011). Aunque la recuperación de la cobertura vegetal en Cárcavo es menor que en otras áreas de mayor precipitación y litologías menos erosionables de la Región de Murcia (Pérez-Cutillas et al, 2018).…”

Anthropic changes in the drainage area of catchments can influence dominant erosion processes and sediment sources and mobilize specific carbon pools. It also causes changes in the sedimentary dynamics and thus in the fluvial morphology. At the same time fluvial morphologies can create the conditions for stabilizing organic carbon (OC) in sediments by burial, carbon preservation, slowing down mineralization processes, and terrestrial or aquatic plant colonization. All this might have a significant impact on the fluvial carbon sink or sources. This work explores the impact of changes in the drainage area (reforestation, check-dam building, agricultural abandonment) on fluvial morphology and on the sedimentary carbon sink of an arid and erodible catchment. The methodological approach combines cartographic analysis of land use, geomorphological photointerpretation of the channel and slope-channel connections in 1956 and 2016. Furthermore, soil and sediment sampling across the catchment for organic carbon stock determination was carried out. The watershed underwent a drastic transformation of land use from 1956, changing from an agrarian scenario to a forest pattern in 2016. This evolution altered sedimentological dynamics and fluvial morphologies. The active channel was narrowed (52%) whereas bank erosion (77%) and the adjacent gullies (11%) increased. The inner alluvial plain increased up to 31% and alluvial fans up to 37%. In addition, vegetation in the channel increased up to 16%. All this led to an increase of the total OC pool of fluvial sediments (12%), slightly above than the increase of OC total pool in the soils of the catchment (10%). The ratio of the OC stock sediments/soils was > 0.8, which indicates the large capacity of carbon sequestration of fluvial sediments, with OC stocks larger than those of agricultural soils. It was found that the geomorphological dynamics plays an important role in the OC fluvial flows. In scenarios of channel narrowing and vegetation encroachment of fluvial morphologies, the sediments can stabilize and generate OC sinks. These processes of OC sequestration in dry and ephemeral channels can have a large relevance for various ecosystem services and should be considered in the management of fluvial sedimentary areas.

“…Estas transformaciones en los usos del suelo han sido ampliamente descritas en la Península Ibérica, con incrementos de la cobertura forestal entre el 17 y el 200 % en distintas regiones de España (Nainggolan et al 2012, Gallart y Llorens 2004, Boix-Fayos et al 2007a, Boix-Fayos et al 2008, Morán-Tejeda et al 2010, Arnaez et al 2011, Quiñonero-Rubio et al 2016. Esta recuperación de la cubierta vegetal se manifiesta también en muchas cuencas europeas (Beck et al 2009) y a nivel mundial en un "reverdecimiento" de la Tierra en las tres últimas décadas, documentado recientemente a través de imágenes del satélite NOAA-AVHRR (Zeng et al 2016).…”

Important land cover changes were documented in several areas of the Mediterranean basin with associated hydrological effects. This paper aims at contributing to the characterization of land use changes and vegetation cover in a basin representative of the Mediterranean mountain range, and quantifying the impact of those changes on lateral and vertical flows (discharge and evapotranspiration, respectively). For this purpose, a series of precipitation data and some components of the hydrological cycle were analyzed: streamflow-runoff in two periods (1933-1948 and 1996-2012). In addition, a spatial analysis of land use changes was carried out; this information was used for the spatial analysis of the curve number and evapotranspiration. Main results indicated that precipitation had not changed significantly between both periods, while streamflow declined by a 43 %, together with the loss of 63 % of agricultural areas that were replaced by shrubland and forest. Evapotranspiration increased in 57 % of the drainage area, with an average increase of 20 mm year-1. In general, the partition of rainfall was readjusted due to the recovery and changes of the natural vegetation cover, facilitating a redistribution of water within the hydrological cycle. As a result, the observed increase of vertical fluxes and the decrease of horizontal ones could potentially affect the hydrological resources of the area.
