ABSTRACT

The development of the Monterrey Metropolitan Area (MMA) and human carelessness have severely altered the Santa Catarina River (SCR). The objective of this research was to integrate fieldwork, a digital elevation model, exploratory surveys and satellite images analysis to develop a GIS-based map scale 1:40,000 and 1:5,000 of the Quaternary alluvial terraces and Cretaceous geologic formations present in the SCR. In addition, this study presents river geologic cross-sections, hydraulic conductivity estimates per terrace, a piezometric chart (dry season), and a database of contaminant sources along the river. The main results were the following: three terraces levels were identified, the distribution and hydrogeological properties of the terraces were documented, groundwater flow direction was southwest (SW) to northeast (NE), and 154 contaminant sources were georeferenced. This investigation lays down the basis for future environmental assessments and studies related to the quality and water supply for the MMA.

摘要

蒙特雷都会区 (MMA) 的发展和人类的粗心大意已经严重改变了圣卡塔琳娜河 (SCR)。这项研究的目的是整合实地工作、数字高程模型、探索性调查和卫星图像分析，以开发 SCR 中存在的第四纪冲积阶地和白垩纪地质构造的基于 GIS 的地图比例为 1:40,000 和 1:5,000。此外，这项研究还提供了河流地质横截面、每个阶地的水力传导率估计值、压力图（旱季）和沿河污染物来源的数据库。主要结果如下：确定了三个阶地水平，记录了阶地的分布和水文地质特性，地下水流向为西南（SW）到东北（NE），154 个污染源进行了地理参考。该调查为未来与 MMA 的质量和供水相关的环境评估和研究奠定了基础。
