In this study, the long-term tailing derived from the storage process of contaminants in low-permeability zones is investigated. The release from these areas in the groundwater can be considered a long-term source that often undermines remediation efforts. An Image Analysis technique is used to analyze the process and evaluate the concentrations of a tracer at different points of the test section. Furthermore, the diffusive flux from the low-permeability lenses is determined. To validate the proposed technique, the results are compared with samples, and the diffusive fluxes resulting from the low-permeability zones of the reconstructed aquifer are compared with a theoretical approach.
在本研究中，对低渗透带中污染物储存过程产生的长期拖尾现象进行了研究。这些区域在地下水中的释放可被视为一个长期污染源，常常会破坏修复工作。采用图像分析技术来分析该过程，并评估测试段不同点处示踪剂的浓度。此外，还确定了来自低渗透透镜体的扩散通量。为验证所提出的技术，将结果与样本进行比较，并将重建含水层低渗透带产生的扩散通量与理论方法进行比较。
