Abstract. Quantifying groundwater recharge in crystalline rocks presents great difficulties due to the high heterogeneity of the underground medium (mainly, due to heterogeneity in fracture network, which determines hydraulic parameters of the bedrock like hydraulic conductivity or effective porosity). Traditionally these rocks have been considered to have very low permeability, and their groundwater resources have usually been neglected; however, they can be of local importance when the bedrock presents a net of well-developed fractures. The current European Water Framework Directive requires an efficient management of all groundwater resources; this begins with a proper knowledge of the aquifer and accurate recharge estimation. In this study, an assessment of groundwater resources in the Spanish hydrologic district of Galicia-Costa, dominated by granitic and metasedimentary rocks, was carried out. A water-balance modeling approach was used for estimating recharge rates in nine pilot catchments representatives of both geologic materials. These results were cross-validated with an independent technique, i.e. the chloride mass balance (CMB). A relation among groundwater recharge and annual precipitation according to two different logistic curves was found for both granites and metasedimentary rocks, thus allowing the parameterization of recharge by means of only a few hydrogeological parameters. Total groundwater resources in Galicia-Costa were estimated to be 4427 hm 3 yr −1 . An analysis of spatial and temporal variability of recharge was also carried out.

“…Visual Balan (VB) is a widely used hydrological model (Samper et al 1999, Samper and García-Vera 2004, Espinha Marques et al 2011. It is relatively simple to use and has fewer data requirements than HB.…”

“…In turn, Visual Balan 2.0 (VB) presents an intermediate degree of complexity. This model runs a sequential water balance for the soil, the unsaturated zone and the aquifer and has proven effective in estimating groundwater recharge in different hydrogeological settings (Samper et al 1999, Espinha-Marques et al 2011. The results obtained by means of both models are compared with the classic Thornthwaite model (TW) (Thornthwaite and Mather 1955), a simple and widely used approach that has been modified by different authors (Dripps and Bradbury 2007).…”

Estimating groundwater recharge is essential to ensure the sustainable use of groundwater resources, particularly in arid and semi-arid regions. Soil water balances have been frequently advocated as valuable tools to estimate groundwater recharge. This article compares the performance of three soil water balance models (Hydrobal, Visual Balan v2.0 and Thornthwaite) in the Ventós-Castellar aquifer, Spain. The models were used to simulate wet and dry years. Recharge estimates were transformed into water table fluctuations by means of a lumped groundwater model. These, in turn, were calibrated against piezometric data. Overall, the Hydrobal model shows the best fit between observed and calculated levels (r 2 = 0.84), highlighting the role of soil moisture and vegetation in recharge processes.Key words groundwater recharge; soil water balance; lumped groundwater model; karst aquifers; semi-arid region; Alicante, Spain Performances comparées de modèles de bilan hydrique des sols pour le calcul de la recharge d'aquifères en conditions semi-arides Résumé L'estimation de la recharge des eaux souterraines est essentielle pour permettre l'utilisation durable des ressources en eaux souterraines, en particulier dans les régions arides et semi-arides. Les bilans hydriques des sols ont souvent été recommandés comme de précieux outils pour estimer la recharge des eaux souterraines. Cet article compare les performances des trois modèles de bilan hydrique du sol (Hydrobal, Visual Balan v2.0 et Thornthwaite) sur l'aquifère de Ventós-Castellar, en Espagne. Nous avons appliqué les modèles de simulation sur des années humides et sèches. Les estimations de la recharge ont été transformées en fluctuations du niveau de la nappe au moyen d'un modèle global d'eau souterraine. Ces fluctuations ont été calées à leur tour par rapport aux données piézométriques. Globalement, le modèle Hydrobal donne le meilleur ajustement entre les niveaux observés et calculés (r 2 = 0,84), mettant en évidence le rôle de l'humidité des sols et de la végétation dans les processus de recharge.Mots clefs recharge des eaux souterraines ; bilan hydrique du sol ; modèle global d'eau souterraine ; aquifères karstiques ; région semi-aride ; Alicante ; Espagne

“…The first step was to assess flow regime (streamflow) and recharge through modelling for the historical period . HEC-HMS 3.4 [29] and Visual-BALAN 2.0 [30] were the basic tools used for the baseline (or reference historical period) and future time period, according to the selected climate scenario, the change of crop type cultivation and land use/land cover. Secondly, streamflow and recharge for the A2 (medium high) and B1 (medium low) climate scenarios and the 2025 (2000-2024) and 2050 (2025-2050) time slices were simulated from downscaling the ECHAM5 (GCM) results (Max Plank Institute für Metereologie).…”

Climate change impact on water resources (streamflow and deep natural recharge) based on the downscaled outputs from the ECHAM5 general circulation model (GCM) has been investigated in the Mediterranean basin (Fluvià, Spain) for the A2, B1 greenhouse scenarios and 2000-2024/2025-2050 time slices. The HEC-HMS 3.4 rainfall-runoff numerical model was the basic tool used to generate streamflow for the historical period, and deep natural recharge was calculated from Visual-BALAN 2.0, a water-soil-plant distributed model. The hydrologic and recharge models were employed to generate future climate change hydrographs and the deep recharge amount. Furthermore, the selected future climate scenarios, subject to possible changes in the land use/land cover forecast, were integrated into the models, and water resource impacts were assessed. The multiple combinations of climate model, time slices, greenhouse scenarios, land use/land cover scenarios and hydrological estimation methods resulted in six scenarios. The obtained results estimate an increase in temperature (1.5˝C), a decline in precipitation (17%) and a maximum decrease of 49.5% and 16.8% in runoff and groundwater recharge, respectively, for 2050 (A2) compared to the historical values. Planned land cover scenarios, implying small changes of agricultural and forested land, show no major contribution to future water resource changes. According to the results, the most sensitive parameters conditioning future water resources are changes in temperature and precipitation.
