Andalusia's lowland countryside has a network of small geographically isolated playa lakes scattered across an area of 9000 km2 whose watersheds are mostly occupied by clayey rocks. The hydrological model proposed by the authors seeks to find equilibrium among usefulness, simplicity, and applicability to isolated playas in a semiarid context elsewhere. Based in such model, the authors have used monthly climatic data, water stage measurements, and the basin morphometry of a particular case (Los Jarales playa lake) to calibrate the soil water budget in the catchment and the water inputs from the watershed (runoff plus groundwater flow) at different scales, from monthly to daily. After the hydrologic model was calibrated, the authors implemented simulations with the goal of reproducing the past hydrological dynamics and forecasting water regime changes that would be caused by a modification of the wetland morphometry.

Sierra de Segura is an extensive mountain range, about 3000 km2 in area, with 800–1200 mm/year of precipitation and groundwater resources assessed as 236 hm3/year. Calar del Espino forms a small and representative hydrogeological unit that discharges almost all groundwater flow through the El Tejo spring. Carbonate rocks nearly 500 m thick are exposed over 6 km2 in the core of a synclinal structure and constitute a hanging aquifer. The summit of Calar del Espino (1600–1700 m asl) is a karstic plateau corresponding to a remnant of the Segura post-Miocene paleosurface. Hydrograph analysis and physical and chemical characteristics of the water lead to the conclusion that the El Tejo karstic system shows a heterogeneous degree of karstification, little variability in the physical and chemical characteristics of the water, high dynamic reserves, and a long water residence time.

The carbonate aquifers of Lora and Mingo form part of the hydrogeological unit of Sierra de Estepa (SE Spain). By means of time series analysis and a 1D numerical groundwater model, groundwater exploitation was quantified and the mean annual recharge in both systems was estimated (2001–2004). During this period, the Lora and Mingo aquifers received an average groundwater recharge of 0.29 × 106 m3/year and 0.14 × 106 m3/year, respectively, whereas an average of 0.34 × 106 m3/year and 0.21 × 106 m3/year, respectively, was extracted. These conditions led to a conspicuous lowering of the water table in both systems. In addition, the analysis of the evolution of the main hydrogeochemical parameters of the groundwater showed that the increased pumping rates produced an increase in total dissolved solids, and chloride and sodium ions in both aquifers. In the case of the Lora aquifer, the only ion that presented decreased levels was nitrate. The results show that groundwater pumping in both aquifers should not exceed the mean annual recharge of 0.29 × 106 m3/year and 0.14 × 106 m3/year in the Lora and Mingo aquifers, respectively. Nevertheless, it would be advisable to reduce pumping rates to below these values in order to restore piezometric levels and improve groundwater quality for different uses in the future. Les aquifères carbonatés de Lora et Mingo constituent une partie de l’unité hydrogéologique de la Sierra de Estepa (S.E. de l’Espagne). Au moyen d’analyses de séries chronologiques et d’un modèle de nappe unidimentionnel, l’exhaure a été quantifiée et la recharge annuelle des deux aquifères estimée (2001–2004). Durant cette période, les recharges moyennes annuelles des aquifères Lora et Mingo ont été respectivement 0.29 × 106 m3 et 0.14 × 106 m3, alors que les prélèvements étaient respectivement 0.34 × 106 m3 et 0.21 × 106 m3. Cette situation a conduit à un abaissement sensible du niveau piézométrique des deux systèmes. De plus l’analyse de l’évolution des principaux paramètres hydrochimiques a montré que l’augmentation des volumes pompés a entraîné dans les deux aquifères une augmentation de la concentration des sels dissous et des ions chlore et sodium. Dans le cas de l’aquifère Lora, une concentration est en diminution, celle de l’ion nitrate. Les résultats montrent que les prélèvements ne devraient pas excéder la recharge annuelle des aquifères Lora et Mingo, soit 0.29 × 106 m3 et 0.14 × 106 m3 respectivement. Il serait souhaitable de ramener les volumes pompés à des niveaux inférieurs à ces valeurs afin de rétablir les niveaux piézométriques et d’améliorer la qualité de la nappe pour divers usages futurs. Los acuíferos carbonáticos de Lora y Mingo forman parte de una unidad hidrogeológica de Sierra de Estepa (SE de España). Se cuantificó la explotación de aguas subterráneas y se estimó la recarga media anual en ambos sistemas (2001–2004) por medio de análisis de series temporales y un modelo numérico de aguas subterráneas unidimensional. Durante este período, los acuíferos Lora y Mingo recibieron una recarga promedio de aguas subterráneas de 0.29 × 106 m3/año y 0.14 × 106 m3/año, respectivamente, mientras que se extrajeron un promedio de 0.34 × 106 m3/año y 0.21 × 106 m3/año, respectivamente. Estas condiciones condujeron a un notable descenso de los niveles de agua en ambos sistemas. Además, el análisis de la evolución de los principales parámetros hidrogeológicos de las aguas subterráneas mostraron que el incremento de los ritmos de bombeo produjo un incremente en los sólidos disueltos totales, y en los iones cloruro y sodio en ambos acuíferos. En el caso del acuífero de Lora, el único ión que presentó niveles decrecientes fue el nitrato. Los resultados muestran que el bombeo de aguas subterráneas en ambos acuíferos no debe exceder la recarga media anual de 0.19 × 106 m3/año y 0.15 × 106 m3/año en los acuíferos Lora y Mingo respectivamente. Sin embargo, sería aconsejable disminuir los ritmos de bombeo por debajo de estos valores para restaurar los niveles piezométricos y mejorar la calidad de las aguas subterráneas para diferente usos en el futuro. Lora和Mingo的碳酸盐岩含水层组成了西班牙东南Sierra de Estepa地区的部分水文地质单元。通过时间序列分析和1维地下水数值模拟, 量化了两个含水层系统的地下水开采量和年均补给量 (2001–2004) .在此期间, Lora和Mingo含水层接受的平均补给量分别为29万 m3/y and 14万 m3/y, 而平均开采量分别为34万 m3/y 和 21万 m3/y。导致两系统中地下水位显著下降。另外, 对地下水的主要水文地球化学参数的演变分析表明, 开采量的增加导致了两含水层中总溶解固体、氯、钠离子浓度的增加。在Lora含水层中, 惟一下降的是硝酸盐。结果表明, Lora和Mingo含水层中的地下水开采量不应超过各自的补给量19万 m3/y 和15万m3/y. 应该降低开采量使其低于补给量, 从而恢复含水层测压水位和改进地下水水质, 以备将来之需 Os aquíferos carbonatados de Lora e Mingo fazem parte da unidade hidrogeológica de Serra de Estepa (SE de Espanha). Por intermédio da análise de séries temporais de dados e usando um modelo numérico 1D de fluxo de água subterrânea, a exploração de águas subterrâneas foi quantificada, e estimada a recarga média anual em ambos os sistemas (2001–2004). Durante este período, os aquíferos de Lora e Mingo receberam uma recarga média em termos de águas subterrâneas de 0.29 × 106 m3/ano e 0.14 × 106 m3/ano, respectivamente, ao passo que uma média de 0.34 × 106 m3/ano e 0.21 × 106 m3/ano foi extraída, respectivamente, de cada um dos aquíferos. Estas condições levaram a uma descida conspícua do nível piezométrico em ambos os sistemas. Além disso, a análise da evolução dos principais parâmetros hidrogeoquímicos das águas subterrâneas demonstrou que os aumentos dos caudais de bombagem produziram uma subida no total de sólidos dissolvidos e nos teores de cloretos e de sódio, nos dois aquíferos. No caso do aquífero de Lora, o único ião que apresentou níveis decrescentes de concentração foi o nitrato. Os resultados mostram que os volumes de bombagem de água subterrânea em ambos os aquíferos não deveria exceder o valor da recarga média anual, que é de 0.19 × 106 m3/ano e 0.15 × 106 m3/ano nos aquíferos de Lora e Mingo, respectivamente. Deste modo, será aconselhável reduzir os caudais de bombagem para valores abaixo dos da recarga média anual, de modo a restaurar os níveis piezométricos e a melhorar a qualidade das águas subterrâneas, com vista, no futuro, à possível diversificação dos seus usos.

The analysis and interpretation of physical and limnological parameters combined with hydrochemical (major ions and stable isotopes) analyses enabled us to evaluate the hydrogeological functioning and the hydrogeochemical evolution of groundwater in two adjacent lakes related to a karstic aquifer (Archidona, southern Spain). Lake water, groundwater and the outflow from a spring, were monitored periodically from 1998 to 1999 and sporadically from 2000 to 2006. The evolution of groundwater chemistry from recharge (dolines) to discharge areas (spring) showed an increment of 20% in magnesium and 15% in sulphate, and such higher increments were recorded for the water from the lakes, suggesting the existence of different hydrogeological paths. A simple water budget model, together with morphological interpretation, suggests that groundwater discharge into the lakes is of relative importance to the input into these systems. Finally, we believe that the development of a new typology for hydro-morphological elements, by means of several hydrological factors and the assessment of pressures and impacts will be useful for the correct management of these lakes and other semi-arid aquatic ecosystems.
