ABSTRACT Viguier et al. propose an alternative conceptual model to the one presented by Scheihing to explain observed groundwater table variations at the foothills of the Andean piedmont in the Pampa del Tamarugal. It is demonstrated that the conceptual model of Viguier et al. is deficient. New findings underline that the confined aquifer of the Pampa del Tamarugal exhibits a hydraulic continuity over regional scales as proposed by Scheihing. Accordingly, short hydraulic response times of several months to distant recharge events can be confirmed. It is suggested that the investigated confined aquifer exhibits transient easterly boundary conditions, with easterly boundaries located in the Andean piedmont. These boundaries underly a periodic forcing due to occasional recharge. Several arguments are presented that support that alluvial fan channel recharge is in the investigated cases likely not a significant recharge mechanism (not to be confused with fan apex recharge).

摘要 Viguier 等人。提出了 Scheihing 提出的概念模型的替代概念模型，以解释在 Pampa del Tamarugal 的安第斯山麓山麓观察到的地下水位变化。证明了 Viguier 等人的概念模型。不足。新发现强调，Pampa del Tamarugal 的承压含水层表现出 Scheihing 提出的区域尺度上的水力连续性。因此，可以确认对远程补给事件的几个月的短液压响应时间。这表明调查的承压含水层表现出短暂的东向边界条件，东向边界位于安第斯山麓。由于偶尔的补给，这些边界处于周期性强迫之下。
