The objective of this research was to determine the relationship between the inefficiency of furrow irrigation, the geometric characteristics of agricultural plots and the depletion of the aquifer conditions of the Laguna Bustillos basin (Chihuahua, Mexico) in recent decades (1991-2012). The main results were: a) the analysis of geometric characteristics showed that the Mennonite properties have the least favorable conditions for the use of furrow irrigation; b) the index of inefficiency of furrow irrigation demonstrated the existence of agricultural plots that exceed 2.5 to 13 times the maximum allowed 2019, Instituto Mexicano de Tecnología del Agua.
Groundwater is a strategic resource for economic development, social justice, environmental sustainability, and water governance. The Lower Casas Grandes Basin located in the state of Chihuahua, Mexico is in a semi-arid region that has increasing groundwater demands while confronting regional challenges such as adverse climate change scenarios and depleting aquifers. Even though there is official information about the availability of groundwater, comprehensive aquifer characterization is still uncertain and needs interdisciplinary investigation using a diverse suite of tools and multiple data sources. This study presents a multi-technique framework to evaluate potential sites to drill for groundwater resources. The main components of the methodology included: wellhead leveling correction with a differential global positioning survey to define piezometric levels, principal component analysis using Landsat-8 images, application of geospatial tools, geophysics using Time Domain Electromagnetic Surveys and Vertical Electric Soundings and structural geohydrology to define aquifer characteristics. Results show that the application of the framework enhances the possibility of successful drilling for groundwater while saving time and money using “pin-point” positioning for drilling sites as compared to a traditional extensive groundwater exploration approach. Low resistivity values (35 Ohm-m) were found at depths from 50m to 85m at sites where the regional static water level reached 245 m deep adding a shallow groundwater potential at sites where the intersection of fracture trace was identified. This procedure can be used at other sites where limited or minimum information is available for groundwater exploration to reduce the risk of drilling dry wells in complex hydrogeological environments.
In hydrogeology it is of great interest to examine the temporal and spatial evolution of aquifers. There are different ways of modeling an aquifer: physical models, models based on analog and mathematical techniques. Usually, mathematical techniques involve complex operations difficult to understand for some people, such as differential or partial equations. In contrast, our method requires only a basic knowledge of geometry and trigonometry. Moreover, it is only necessary to know the static level of the aquifer at three different dates. Of course, the results may be limited compared to those that use advanced mathematical methods; however, our method provides a first approximation to determine the behavior of the aquifer through time. Overall, our results allowed us to follow the evolution of the aquifer in detail of various areas of increased extraction and in which removal has been increasing, but also of areas with a considerable recharge during the study period.
Este documento tiene como objetivo identificar modelos de escurrimientos superficiales en la última década. Se realizo una revisión de literatura y se encontraron 56 estudios publicados en los buscadores Google Scholar, Red de Revistas Científicas de América Latina y el Caribe, España y Portugal (Redalyc), Difusión de Alerta en la Red (Dialnet), Scientific Electronic Library Online (SciELO) y Science Direct durante el periodo de 2012 hasta el 2022. La búsqueda se delimitó en artículo científico de libre acceso. Se genero una base de datos en Microsoft Excel 2010. Se registraron referencia, año de publicación, nombre de la revista, área de estudio, entidad, país, objetivo de la investigación, variables utilizadas y abreviación de modelos de escurrimientos superficiales. El 7 % de los artículos publicados se concentran en la revista Tecnología y Ciencias del Agua. Argentina ocupa el primer lugar en estudios publicados y 80 % de las áreas de estudios es en cuencas hidrográficas. Los modelos más utilizados para estimar, evaluar, predecir, modelar y simular los escurrimientos superficiales son Herramienta para la Evaluación del Suelo y Agua (SWAT) y Servicio de Conservación de Suelo-Número de curva (SCS-CN).
Groundwater is a strategic resource for economic development, social justice, environmental sustainability, and water governance. The lower Casas Grandes River Basin, located in the state of Chihuahua, México, is in a semi-arid region with increasing groundwater demand and regional challenges such as drought and depletion of aquifers. Even though there is official information about the availability of groundwater, a comprehensive aquifer characterization requiring an interdisciplinary investigation using a diverse suite of tools and multiple data sources has yet to be carried out. This study presents a multi-technique framework to evaluate potential sites to drill for groundwater resources and reduce the risk of unsuccessful drilling. The main components of the methodology include wellhead leveling correction with a differential global positioning survey to define piezometric levels, principal component analysis using LANDSAT-8 images, application of geospatial tools, geophysics analysis using time domain electromagnetic surveys (TDES) and vertical electric soundings (VES), and structural geohydrology to define aquifer characteristics. The results showed that using the proposed framework steps improved the possibility of identifying subsurface layers with lower resistivity values that could be related to groundwater. Low resistivity values (35 Ohm-m) were found at depths from 50 to 85 m at sites where the regional static water level reached a depth of 245 m, indicating the potential location of a shallow groundwater resource at a site where the intersection of a fracture trace was identified. This procedure can be used in other regions in the world where limited information is available for groundwater exploration, thus reducing the risk of drilling dry wells in complex hydrogeological environments.
La presente investigación tiene como objetivo la monitorización del cambio en los patrones de distribución espacial del uso del suelo urbano que se ha presentado en la zona de presión intermunicipal de Chihuahua en el periodo 1995-2015. Se utilizó el software FRAGSTATS para el cálculo de las métricas de análisis de la ecología del paisaje. Los resultados indican que el crecimiento del suelo destinado a vivienda que se presentó en el periodo de estudio se encuentra en consonancia con el modelo de ciudad dispersa, caracterizado por la baja densidad edificatoria y la preponderancia del transporte privado por carretera.
Este artículo presenta los resultados de una investigación sobre el índice de motorización en Ciudad Cuauhtémoc,una ciudad al norte de México que tiene condiciones de oferta vehiculares anormales debido a la importación ilegal de coches. Los datos fueron generados a partir del análisis de una muestra de 1296 vehículos mediante una técnica de transecto, que consiste en una selección aleatoria de muestras en una zona de forma lineal. La investigación fue repetida en dos ocasiones con resultados similares. Los resultados revelan la existencia de entre 38 979 y 40 074 coches de circulación ilegal de los 124 686 coches totales en la ciudad. Se contrastan los resultados obtenidos con losíndices de motorización ofrecidos por el Instituto Nacional de Estadística y Geografía (INEGI), que solo contabiliza los coches de circulación legal. Asimismo, se ofrece una reflexión sobre las posibles consecuencias de la política actual de gasto público, así como el efecto de este en la toma de decisiones de las personas cuando no tienen acceso a un vehículo de circulación legal.
