Abstract

Hydrogeochemistry is an essential tool for the verification of conceptual models, especially of groundwater flow models. This is even more relevant when dealing with complex hydrogeological models that have intercalating layers with different degrees of permeability, and regional flows contributing to the system. The hydrogeochemical characteristics of the Uraba-Colombia Aquifer and geological cross-sections were studied to establish possible processes that explain the groundwater flow evolution and the recharge zones. 4 flow lines were considered to show the groundwater evolution from Ca2+-HCO3 - facies and a TDS concentration of approximately 400 mg/L, trough Ca2+-Mg2+-HCO3 - and Na+ -Mg2+-HCO3 - facies, ending with Na+ -HCO3 - facies close to discharge area, with TDS=1,550 mg/L. Data on stable isotopes confirmed the groundwater flow directions. It is also clear that evolution orders correspond to the possible flow rates in areas with a homogeneous gradient, but with higher hydraulic conductivity conditions to the south and center, compared to the north.

区域流系统的水文地球化学特征与识别。案例研究:哥伦比亚乌拉布湾的含水层

水文地球化学是验证概念模型，特别是地下水流动模型的重要工具。当处理复杂的水文地质模型时，这一点甚至更为重要，因为这些模型具有不同渗透率的夹层，以及对系统有贡献的区域流动。研究了乌拉巴-哥伦比亚含水层的水文地球化学特征和地质剖面，建立了解释地下水流动演化和补给带的可能过程。考虑了4条流水线，表明地下水从Ca2+- hco3 -相演化，TDS浓度约为400 mg/L，通过Ca2+- mg2 +- hco3 -和Na+ - mg2 +- hco3 -相，以靠近排放区的Na+ - hco3 -相结束，TDS= 1550 mg/L。稳定同位素的数据证实了地下水的流向。同样清楚的是，演化顺序对应于具有均匀梯度的区域的可能流速，但与北部相比，南部和中部的水力导率条件更高。

期刊介绍： Revista Facultad de Ingenieria started in 1984 and is a publication of the School of Engineering at the University of Antioquia. The main objective of the journal is to promote and stimulate the publishing of national and international scientific research results. The journal publishes original articles, resulting from scientific research, experimental and or simulation studies in engineering sciences, technology, and similar disciplines (Electronics, Telecommunications, Bioengineering, Biotechnology, Electrical, Computer Science, Mechanical, Chemical, Environmental, Materials, Sanitary, Civil and Industrial Engineering). In exceptional cases, the journal will publish insightful articles related to current important subjects, or revision articles representing a significant contribution to the contextualization of the state of the art in a known relevant topic. Case reports will only be published when those cases are related to studies in which the validity of a methodology is being proven for the first time, or when a significant contribution to the knowledge of an unexplored system can be proven. All published articles have undergone a peer review process, carried out by experts recognized for their knowledge and contributions to the relevant field. To adapt the Journal to international standards and to promote the visibility of the published articles; and therefore, to have a greater impact in the global academic community, after November 1st 2013, the journal will accept only manuscripts written in English for reviewing and publication. Revista Facultad de Ingeniería –redin is entirely financed by University of Antioquia Since 2015, every article accepted for publication in the journal is assigned a DOI number.
