Abstract

A literature review of the impacts of anticipated climate change on unconfined aquifers is presented along with a conceptual framework for evaluating the complex responses of surface and subsurface hydrology to climate variables in cold regions The framework offers a way to conceptualize how changes in one component of the system may impact another by delineating the relationships among climate drivers hydrological responses and groundwater responses in a straightforward manner The model is elaborated in the context of shallow unconfined aquifers in the boreal environment of Finland In cold conditions climate change is expected to reduce snow cover and soil frost and increase winter floods The annual surface water level maximum will occur earlier in spring and water levels will decrease in summer due to higher evapotranspiration rates The maximum recharge and groundwater level are expected to occur earlier in the year Lower groundwater levels are expected in summer due to higher evapotranspiration rates The flow regimes between shallow unconfined aquifers and surface water may change affecting water quantity and quality in the surface and groundwater systemsL’étude présente un inventaire bibliographique des impacts du changement climatique prévisible sur les aquifères libres ainsi qu’un cadre conceptuel pour l’évaluation des réponses hydrologiques complexes en surface et subsurface aux variables climatiques dans les régions froides L’étude propose un mode de conceptualisation de l’incidence de la variation de l’une des composantes du système sur les autres en établissant des relations linéaires entre paramètres climatiques et réponses hydrologiques de l’aquifère Le modèle élaboré concerne les aquifères libres peu profonds dans l’environnement boréal de la Finlande Dans des conditions climatiques froides on s’attend à ce qu’un changement climatique entraîne une réduction de la couverture neigeuse et des gelées ainsi qu’une augmentation des inondations hivernales La crue maximale a lieu plus tôt au printemps et les niveaux d’eau décroissent en été en raison d’un taux d’évapotranspiration plus élevé La recharge et le niveau maximal de la nappe sont attendus plus tôt dans l’année L’étiage de la nappe est attendu en été en raison de taux d’évapotranspiration plus élevés Le régime des échanges entre aquifères libres peu profonds et eaux de surface peut changer affectant la qualité et les réserves des eaux de surface et celles des nappesSe presenta una revisión de la literatura del cambio climático anticipado sobre acuíferos no confinados conjuntamente con un marco conceptual para evaluar las respuestas complejas de la hidrología superficial y subsuperficial a las variables climáticas en regiones frías El marco de referencia ofrece una manera de conceptualizar como los cambios en una componente del sistema pueden impactar en otras delineando las relaciones entre las forzantes climáticas respuestas hidrológicas y respuestas de las aguas subterráneas en una forma directa El modelo está elaborado en un contexto de acuíferos no confinados someros en el ambiente boreal de Finlandia En regiones frías se espera que el cambio climático reduzca la cubierta de nieve y el suelo congelado e incremente las inundaciones de invierno El máximo nivel anual de agua superficial ocurrirá antes en primavera y los niveles de agua decrecerán en verano debido a los más altos ritmos de evapotranspiración Se espera que la recarga máxima y niveles de aguas subterráneas ocurran antes en el año Los niveles más bajos de aguas subterráneas son esperados en verano debido a más altos ritmos de evapotranspiración El régimen de flujo entre los acuíferos no confinados someros y el agua superficial puede cambiar afectando la cantidad y calidad del agua en los sistemas superficiales y subterráneos评述了未来气候变化对潜水含水层影响的研究 并阐述了评价寒冷地区地表和地下水文对气候变化综合响应的概念框架。该框架通过直接描述气候驱动力、水文响应及地下水响应之间的相互关系 提供了一种概化系统内一种组分变化影响另一种组分的方法。在芬兰北部的浅层潜水含水层对该模型进行了详细研究。在寒冷条件下 气候变暖预计会减少积雪量和冻土含量并增加冬季径流量。年地表水最高水位在春季会来的更早 夏季则由于蒸散发量大而使水位有所降低。最大补给量和最高地下水位预计会提前到来。由于蒸发量较大 夏季地下水位会相对较低。潜水含水层和地表水之间的水流场可能会改变并影响到地表和地下水的质和量。Apresentase uma revisão bibliográfica sobre os impactes das alterações climáticas em aquíferos livres juntamente com um enquadramento conceptual de avaliação das respostas complexas dos meios hidrológicos superficiais e subterrâneos às variáveis climáticas em regiões frias O enquadramento permite conceptualizar o modo como mudanças numa componente do sistema podem traduzirse em impactes noutra componente através da definição expedita das relações entre variáveis climáticas comportamento hidrológico e comportamento das águas subterrâneas O modelo é elaborado no contexto de aquíferos livres pouco profundos dos ambientes setentrionais da Finlândia Em regiões frias esperase que as alterações climáticas se traduzam numa redução da cobertura de neve e no aumento de cheias durante o inverno O máximo anual do nível de água superficial ocorrerá mais cedo durante a primavera e os níveis de água diminuirão no verão devido ao aumento da evapotranspiração A recarga e os níveis de água subterrânea máximos devem registarse mais cedo durante o ano Esperase que os níveis de água subterrânea durante o verão sejam mais baixos devido ao aumento da evapotranspiração Os regimes de fluxo entre águas superficiais e aquíferos livres pouco profundos podem ser alterados afectando o volume e qualidade da água nos sistemas hidrológicos superficiais e subterrâneos
