Traditional numerical methods for the delineation of wellhead protection areas span deterministic and probabilistic approaches. They provide time‐related capture zones. However, none of the existing approaches identifies the groundwater contribution areas related to each source or sink. In this work, the worthiness of the so‐called double delineation approach was extended. This task was achieved by simple postprocessing of its dual outputs leading to a highly efficient screening tool. In the particular context of geothermal resources management through the well doublets of the Dogger aquifer in the Paris Basin (France), the approach was extended to forecast the compositional heat breakthrough at production wells. Hence, cold‐water breakthrough and temperature decline in production wells are timely assessed in low‐enthalpy geothermal reservoirs. The method quantifies how groundwater volumes are moving through space and time between any couple of source and sink. It provides unprecedented tools advancing the enhanced understanding of water resources systems functioning. It is highly recommended to implement the presented concepts in the current and future generations of community groundwater models.

双重描述井双峰系统中纠缠干扰的方法

界定井口保护区的传统数值方法跨越确定性和概率性方法。它们提供了与时间相关的捕获区域。但是，现有方法均未确定与每个水源或汇有关的地下水贡献区域。在这项工作中，扩展了所谓的双重划界方法的价值。这项任务是通过对其双重输出进行简单的后处理而实现的，从而形成了高效的筛选工具。在通过巴黎盆地（法国）的Dogger含水层的双重井进行地热资源管理的特殊情况下，该方法已扩展为预测生产井的成分热突破。因此，及时在低焓地热储层中评估生产井的冷水突破和温度下降。该方法量化了地下水量如何在任意两个水源和水槽之间通过空间和时间运动。它提供了空前的工具，有助于加深对水资源系统功能的理解。强烈建议在当前和未来的社区地下水模型中实施提出的概念。
