Modeling of groundwater flow and water use for San Luis Potosí Valley aquifer system
(2014)"Land use changes are currently one of the indisputable factors in the alteration of processes and cycles of the aquifer system in the San Luis Potosí Valley. Due to its importance, is considered indispensable to investigate ... -
The VISHMOD methodology with hydrochemical modeling in intermountain (karstic) aquifers: case of the Sierra Madre Oriental, Mexico
(2014)"Hydrogeochemistry can be studied qualitatively using graphics such as scatter plots and Piper, Durov, and Schoeller diagrams, among others, and quantitatively by applying mass balance mixing models. The VISHMOD methodology ... -
Estimation of total yearly CO2 emissions by wildfires in Mexico during the period 1999–2010
(Hindawi, 2014)"The phenomenon of wildfires became a global environmental problem which demands estimations of their CO2 emissions. Wildfires have deteriorated the air quality increasingly. Using available information on documented ... -

(2014)"Uno de los problemas más importantes en zonas áridas es el relacionado con la exploración y aprovechamiento de agua subterránea. En este trabajo se presenta el método magnético aéreo y terrestre como herramienta para la ... -
Bottom topography, recent sedimentation and water volume of the Cerro Prieto Dam, NE Mexico
(2014)"The Cerro Prieto dam, a relatively small water reservoir in NE Mexico, is one of the main resources of potable water for Monterrey, a city with a population of about four million inhabitants. A high resolution seismic ... -
Dispersion of atmospheric coarse particulate matter in the San Luis Potosí, Mexico, urban area
(Universidad Nacional Autónoma de México, Centro de Ciencias de la Atmósfera, 2014)"La contaminación atmosférica en áreas urbanas de México se ha convertido en un problema grave. Por ello, el estudio de la evolución espacial y temporal de las concentraciones del material particulado es un asunto importante. ... -
An unusual syn-eruptive bimodal eruption: The Holocene Cuicuiltic Member at Los Humeros caldera, Mexico
(2014-02)"The Cuicuiltic Member (CM) at Los Humeros Caldera, eastern Mexican Volcanic Belt is a Holocene (6.4 ka B.P.) succession of alternated fallout deposits of contrasting composition (trachydacite pumice and basaltic andesite ... -
Paleozoic exotic blocks of the crimean mountains: stratigraphy and origin
(2014-08)"Based on numerous geological data obtained by the authors for several decades, the stratification of Permian and Carboniferous ancient and exotic blocks of Crimean Mountains is performed. The sequence of geological events ... -
Transparency of cosmic radio waves caused by seismic and volcano activities
(2014-09)"The generation of different waves in the atmosphere and ionosphere caused by seismic and volcano activities has changed the transparency for cosmic radio waves. It is possible to analyze two cases: the first case caused ... -
Cálculo del índice de pobreza del agua en el acuífero de Santo Domingo, S.L.P.
(2015)"La compleja interrelación que existe entre el hombre y el agua es muy estrecha pues, este último, brinda beneficios de bienestar, producción y desarrollo. Lo que conlleva a un análisis de evaluación, de mayor detalle, en ... -
Análisis de riesgo por inundación en la zona metropolitana de San Luis Potosí
(2015)"En la Zona Metropolitana de San Luis Potosí se presentan inundaciones asociadas con lluvias de corta duración y altas intensidades éstas no corresponden a inundaciones convencionales, en el sentido que difícilmente se ... -
Air quality deterioration of urban areas caused by wildfires in a natural reservoir forest of Mexico
(Hindawi, 2015)"Many regions of the world suffer loss of vegetation and reduced air quality due to wildfires. Studies on aerosol emissions by wildfires often discuss the negative effects of atmospheric contaminants from a regional or ... -
Southward migration of magmatic activity in the Colima volcanic complex, Mexico: an ongoing process
(2015)"The Colima Volcanic Complex trends in a nearly N-S direction in western Mexico, and one of its structures, Colima volcano, is the most historically active volcano in the country. Immediately to the N, there is another ... -
