“…3). The result indicates that the annual runoff and soil loss are not necessarily consistent with the annual conditions of total rainfall, which agrees with some other studies (Cantón et al, 2001;Busnelli et al, 2006). The reasons for this are complex, but mainly due to the high fluctuations and variabilities of temporal rainfall (Hogarth et al, 2004;Nearing et al, 2005;Busnelli et al, 2006).…”

“…Sediment yields of hundreds of tonnes per square kilometre and per year have been estimated Nadal-Romero et al, 2008a;Regüés et al, 2009;López-Tarazón et al, 2012), although the area considered plays a major role in determining the yield , 2012d. In semi-arid and arid regions, the dramatic badland landscapes also suggest the occurrence of high erosion rates, although the low mean precipitation results in relatively low sediment yield (Cantón et al, 2001;Gallart et al, 2002) For the arid badlands (i.e. in Near East including Turkey, Syria, Lebanon, Israel and Jordan), the low level of erosion processes has led to the conclusion that they may have been more humid areas in the past (Yair et al, 1980).…”

Intense erosion processes are widespread in the Mediterranean region, and include sheet wash erosion, rilling, gullying, shallow landsliding, and the development of large and active badlands in both subhumid and semi-arid areas. This review analyses the main environmental and human features related to soil erosion processes, and the main factors that explain the extreme variability of factors influencing soil erosion, particularly recent land use changes. The importance of erosion in the Mediterranean is related to the long history of human activity in a region characterized by low levels of annual precipitation, the occurrence of intense rainstorms and long-lasting droughts, high evapotranspiration, the presence of steep slopes and the occurrence of recent tectonic activity, together with the recurrent use of fire, overgrazing and farming. These factors have resulted in a complex landscape in which intensification and abandonment, wealth and poverty can co-exist. The changing conditions of national and international markets and the evolution of population pressure are now the main drivers explaining land use changes, including farmland abandonment in mountain areas, the expansion of some subsidized crops to marginal lands, and the development of new terraces affected by landslides and intense soil erosion during extreme rainstorm events. The occurrence of human-related forest fires affecting thousands of hectares each year is an increasing problem in both the northern and southern areas of the Mediterranean basin. Here, we highlight the rise of new scientific challenges in controlling the negative consequences of soil erosion in the Mediterranean region: (i) to reduce the effects and extent of forest fires, and restructure the spatial organization of abandoned landscapes; (ii) to provide guidance for making EU agricultural policy more adapted to the complexity and fragility of Mediterranean environments; (iii) to develop field methods and models to improve the identification of runoff and sediment contributing areas; (iv) to contribute to the conservation of landscapes (i.e. bench-terraced fields) having high cultural and productivity values; (v) to improve knowledge of the hydrological and geomorphological functioning of badlands, with the aim of reducing sediment yield and accessibility; (vi) to better understand the effect of climate change on soil erosion in the Mediterranean region; and (vii) to improve quantitative information on long-term soil erosion.

“…The technical characteristics of SBIB probes, their calibration as well as successful results with replicates of the same prototype used in different soils, are detailed in different publications (Puigdefábregas et al, , 1998Vidal et al, 1996;Domingo et al, 1999Domingo et al, , 2001Cantón et al, 2001Cantón et al, , 2004. Beginning in July 2003, six probes were installed in a 10 Â 10 m area the eddy tower at a depth of 0.06 m. Moreover, at the end of 2003, six additional y probes were installed in the same place at two depths (three at a depth of 0.06 m and three more at 0.25 m depth), such that y data at two depths are available only from 12 February 2004 to 31 August 2005.…”

This paper analyses the temporal dynamics of soil water balance components in a representative recharge area of the Sierra de Gádor (Almeria, southeastern Spain) in two hydrological years. Two approaches are used to estimate daily potential recharge (PR): Approach 1 based on deriving PR from the water balance as the difference between measurements of rainfall (P) and actual evapotranspiration (E) obtained by eddy covariance; and Approach 2 with PR obtained from the dynamic pattern of the soil moisture (y) recorded at two depths in the site's thin soil (average 0.35 m thickess). For the hydrological year 2003/04, which was slightly drier than the 30-year average, E accounted for 64% of rainfall and occurred mainly in late spring and early summer. The PR estimated by Approach 1 was 181 AE 18 mm year -1 (36% of rainfall), suggesting an effective groundwater recharge in the study area. In the unusually dry hydrological year 2004/05, E was about 215 mm year -1 , close to the annual rainfall input, and allowing very little (8 AE 12 mm year -1 ) PR according to Approach 1. Estimation of PR based on Approach 2 resulted in PR rates lower than those found by Approach 1, because Approach 2 does not take into account the recharge that occurs through preferential flow pathways (cracks, joints and fissures) which were not monitored with the y probes. Moreover, using Approach 2, the PR estimates differed widely depending on the time scale considered: with daily mean y data, PR estimation was lower, especially in late spring, while y data at 30 min resolution yielded a more reliable prediction of the fraction of total PR resulting from the downward movement of soil water by gravity.Key words potential recharge; evapotranspiration; soil moisture; soil water balance; Mediterranean; Sierra de Gádor Dynamique temporelle des composantes du bilan hydrique du sol dans une chaine karstique du sud-est de l'Espagne: estimation de la recharge potentielle Résumé Ce travail analyse la dynamique temporelle des composantes du bilan hydrique du sol dans une zone de recharge représentative de la Sierra de Gador (Almeria, SE de l'Espagne) pendant deux années hydrologiques. Deux approches ont été utilisées pour estimer la recharge potentielle journalière (RP): dans l'approche 1, RP est calculée à partir de la différence entre les mesures de pluie (P) et d'évapotranspiration réelle (E) obtenues par la méthode de la covariance turbulente; dans l'approche 2, RP est obtenue à partir de l'humidité du sol (y) mesurée à deux profondeurs dans les sols peu profonds du site (épaisseur moyenne de 0.35 m).
