Abstract
Determining hydrogeological properties of the rock materials that constitute an aquifer through stress tests or laboratory tests presents inherent complications. An alternative tool that has significant advantages is the study of the groundwater-level response as a result of the pore-pressure variation caused by the internal structure deformation of the aquifer induced by barometric pressure and solid Earth tide. The purpose of this study was to estimate the values of the physical/hydraulic properties of the geological materials that constitute the Guadalupe Valley Aquifer based on the analysis of the groundwater-level response to barometric pressure and solid Earth tide. Representative values of specific storage (1.27 × 10−6 to 2.78 × 10−6 m−1), porosity (14–34%), storage coefficient (3.10 × 10−5 to 10.45 × 10−5), transmissivity (6.67 × 10−7 to 1.29 × 10−4 m2∙s−1), and hydraulic conductivity (2.30 × 10−3 to 2.97 × 10−1 m∙d−1) were estimated. The values obtained are consistent with the type of geological materials identified in the vicinity of the analyzed wells and values reported in previous studies. This analysis represents helpful information that can be considered a framework to design and assess management strategies for groundwater resources in the overexploited Guadalupe Valley Aquifer.
Highlights
Water supply for human consumption, agricultural, and industrial activities is a crucial topic for developing the northwest semi-arid zones of Mexico
This study synthesized methods for estimating hydraulic aquifer properties from water-level fluctuations measured in a set of monitoring wells at Guadalupe Valley, Mexico
Based on our literature review, the calculated specific storage values correspond to the first estimations reported in the Guadalupe Valley Aquifer
Summary
Water supply for human consumption, agricultural, and industrial activities is a crucial topic for developing the northwest semi-arid zones of Mexico. The Guadalupe Valley has had groundwater exploitations as its primary source of water. This intense anthropogenic activity has led to a recharge-extraction deficit, resulting in an excessive decrease in groundwater levels, compromising water availability in the region [1,2,3,4]. This situation raises the need to conduct interdisciplinary studies that provide technical and scientific information to design and evaluate new water-resource-management strategies. As part of the hydrogeologicalmonitoring recommendations, continuous monitoring wells were instrumented by using pressure transducers [6]
