La determinación precisa de la variación de la recarga de agua subterránea es una tarea fundamental para la planificación sostenible de los recursos hídricos subterráneos, sobre todo en acuíferos fuertemente presionados. Con el objetivo de determinar la variabilidad espacial y temporal de la recarga de agua subterránea en un acuífero urbano con cli...
Article
Groundwater overexploitation occurs throughout Central Mexico and is a major threat to the sustainable development of the region. The two most direct impacts are on groundwater/surface water interactions and uneven land subsidence causing ground fracturing. The latter implies frequent and costly repairs to linear urban infrastructure such as roads...

Las características químicas e isotópicas del acuífero urbano de San Salvador, y de los sistemas de agua potable (SAP) y aguas residuales (SAR) se evaluaron en un área de 362 km2 para detectar si las fugas en dichos sistemas están recargando el acuífero y modificando su calidad natural. Un total de 37 sitios de muestreo conformados por pozos, manan...

Population pressure, urbanization, and industrial developments, among other factors, have resulted in severe degradation of environmental resources such as wetlands. Thus, a groundwater model (MODFLOW) was integrated with a particle tracking MODPATH model to simulate the hydrodynamic flow head field and to analyze the vulnerability of the Salburua...
Article
Urban infrastructures built over karst settings may be at risk of collapse due to hydro-chemical erosion of underlying rock structures. In such settings, mapping cave networks and monitoring ground stability is important to assure civil safety and guide future infrastructure development decisions. However, no technique can directly and comprehensiv...
Article
This paper illustrates how InSAR alone can be used to delineate potential ground fractures related to aquifer system compaction. An InSAR-derived ground fracturing map of the Toluca Valley, Mexico, is produced and validated through a field campaign. The results are of great interest to support sustainable urbanization and show that InSAR processing...

The estimation of soil hydraulic properties in the vadose zone has some issues, such as accuracy, acquisition time, and cost. Thus, the estimation of the unsaturated flow should be precisely analyzed; their evaluation has important implications in transient process of infiltration due to the high nonlinearity of soil water characteristics. It is al...

The estimation of soil hydraulic properties in the vadose zone has some issues, such as accuracy, acquisition time, and cost. In this study, an inexpensive automated test column (ATC) was developed to characterize water flow in a homogeneous unsaturated porous medium by the simultaneous estimation of three hydraulic state variables: water content,...
Article
Full-text available
Groundwater deficits occur in several areas of Central Mexico, where water resource assessment is limited by the availability and reliability of field data. In this context, GRACE and InSAR are used to remotely assess groundwater storage loss in one of Mexico's most important watersheds in terms of size and economic activity: the Lerma-Santiago-Pac...

Hard water causes many problems in domestic and industrial usage, which has to be removed using cost-effective technologies. To achieve this, the main goal of this study is to assess and optimize the factors controlling water softening applications. The research approach included a combined use of batch and column experiments performed in laborator...

Full-text available
Significant structural damages to urban infrastructures caused by compaction of over-exploited aquifers are an important problem in Central Mexico. While the case of Mexico City has been well-documented, insight into land subsidence problems in other cities of Central Mexico is still limited. Among the cities concerned, we present and discuss the c...

Water from karstic springs contains high concentrations of total hardness from the dissolving of geological carbonate formations, which prohibits its use for domestic and industrial purposes in these zones. The approach used consisted of analyzing geochemical and natural softening process to estimate the factors that control water hardness in karst...

Groundwater is the main source of water supply in Central Mexico. In the last decades, overexploitation of the aquifer led to environmental and socioeconomic issues, impacting more than 25 million Mexicans. In a context of a lack of reliable data in assessing groundwater overexploitation, space borne sensors bring useful information for groundwater...

In the context of a lack of reliable data in assessing groundwater overexploitation, space borne sensors bring useful information. While space-borne SAR and gravimetric data are now used to study groundwater, their interoperability is still poorly studied. In this paper, we apply two cutting-edge techniques for the deficit assessment of one of Mexi...

In the Toluca valley, important surface displacements have occurred in response to the activation of recently generated fractures, which locally condition the infiltration of contaminated surface water. This is the case of a fractured zone in the community Santiago Tianguistenco (Mexico State), to which wastewater, mainly domestic, from about 14,00...
