Seasonal ecosystems play a crucial role in environmental regulation and biodiversity by hosting complex ecological dynamics that vary with climatic conditions. The Chaschoc-Sejá wetlands are key example of such systems southeastern Mexico. interaction between the lagoon system Usumacinta River is highly dynamic; during rainy season, lagoons increase volume, reaching depths 8 to 10 meters. However, completely dry up leaving vegetation at surface level. This project aims...

Mexico City, located in a lacustrine basin on highly heterogeneous terrain, presents complex and unique scenario for studying sinkhole formation. Unlike karst regions, where these phenomena are typically associated with natural rock dissolution processes, City they linked to specific interaction of geological, hydrological, anthropogenic factors. Between 2017 2020, over 500 sinkholes were recorded, significantly impacting infrastructure public safety. This context is particularly significant...

Acid mine drainage (AMD) is a severe environmental issue associated with the generation of finely milled rock waste containing high concentrations sulfide minerals and potentially toxic elements (PTEs) during mining activities. The formation secondary minerals, such as sulfates iron oxyhydroxides, results from oxidation subsequent acid neutralization by carbonate silicate making them key indicators AMD. Efficient identification these crucial for monitoring their impact on soils.This study...

Endemic species comprise 16% of the floral on Guadalupe Island, including three arboreal species. Almost 96% forest coverage was lost due to impacts related feral goats and wildfires. To date, have been eradicated restoration native vegetation communities is underway. The purpose this study develop a 3D Structural Classification Method (3D-SCM) using Terrestrial Laser Scanner (TLS) for mapping vertical structure automatically characterize its physical attributes. Several TLS scans were...

Sinkholes pose a significant hazard in Mexico City (CDMX), causing substantial economic damage. While the link between sinkhole formation and groundwater extraction has been studied, specific mechanisms vary by site. Our overall aim is to characterize phenomenon of sinkholes CDMX. To achieve this, we create database with 13 influencing factors, including population density, well distance faults, fractures, roads, streams, elevation, slope, clay thickness, lithology, subsidence rate,...

El diámetro a altura pecho (DAP), total copa se obtuvieron con seis 1)...

Flooding is a constant danger in many cities. To prevent and mitigate their impacts, mathematical modeling carried out to simulate the behavior of flow within environment define possible flood zones. Incorporating vegetation hydraulic models pivotal for understanding its impact on characteristics, sediment transport, channel morphology. The Santa Catarina River Monterrey, Nuevo León, Mexico, grapples with irregular water flows. During dry seasons, minimal levels promote unchecked...

Objective: The objective of this study is to investigate the accuracy volcanic ash detection using satellite imagery, improve existing monitoring tools adapt them Popocatépetl volcano in Mexico. Theoretical Framework: Volcanic via remote sensing employs Pavolonis' algorithms that compare radiances thermal and mid-infrared spectrum. This approach differentiates from clouds water vapor by leveraging its differential absorption. Satellites such as GOES-16, which capture multispectral data,...

Sinkholes are a geological phenomenon that appears as closed funnel-shaped surface depression, where water can stagnate and drain into the subsoil. This occurs mainly in karst environments, however it also occur multiple generated by natural anthropogenic processes, such subsurface erosion, changes groundwater levels extraction, among others. The main distinctive feature of sinkholes is their presence not detectable until sudden collapse layer soil occurs, generating significant risk for...

Multiple factors influence the risk of heat stroke and that, collectively, define vulnerability population. This can be physiologically differentiated by older adults children, gender, or due to level exposure sporting activities labor, among others. During last two decades, hot extreme events are drastically increasing related climate change other phenomena such as El Niño event. The World Health Organization estimates that more than 70,000 heat-related deaths occurred in Europe...

Abstract. Flooding poses a persistent threat to urban areas, prompting the use of mathematical modeling understand flow dynamics and delineate flood zones. Integrating vegetation into hydraulic models is crucial for assessing its effects on characteristics, sediment transport, channel morphology. The Santa Catarina River in Monterrey, Mexico, experiences irregular water levels, leading unchecked growth during dry seasons loss extreme weather events like hurricanes. This study utilized two...

<p>The present project aims to make a preliminary assessment of the volcanic risk represented by Apan Volcanic Field (CVA). The methodology was divided into two parts. In first, Digital Elevation Models (DEM) published official sources were used identify unreported structures and perform morphometric analysis previously dated structures. second stage, new DEM developed from interferometric methodologies compare results with those obtained sources. Two SAR satellite images...

Land use classification studies help to quantify the changes in forest cover that may occur at a given site over time. This quantification helps us understand effect of natural and anthropogenic processes study site. Activities such as agriculture, cattle ranching illegal logging, which turn are related evolution site's public policies, can be evaluated through studies. Tenosique area, southeast Mexico, is clear example consequences these programs, being largely benefited by economic consent...
