We consider a problem of high-resolution array radar/SAR imaging formalized in terms of a nonlinear ill-posed inverse problem of nonparametric estimation of the power spatial spectrum pattern (SSP) of the random wavefield scattered from a remotely sensed scene observed through a kernel signal formation operator and contaminated with random Gaussian...
The method's development to detect oil-spills, and concentration monitoring of marine environments, are essential in emergency response. To develop a classification model, this work was based on the spectral response of surfaces using reflectance data, and machine learning (ML) techniques, with the objective of detecting oil in Landsat imagery. Add...
This paper proposes an approach of fusion geo-referenced and non-georeferenced data. These data can be acquired by a) unmanned surface vehicles (USVs), b) unmanned aerial vehicles (UAVs), c) airborne and submersible optical sensors, d) acoustic sensors and e) aquatic sound profiling instruments. The test scenario consisted of monitoring and morphol...
The city of Morelia has been affected by Structurally-Controlled Differential Subsidence (SCDS) since at least 1983, modifying civil structures and infrastructure through the appearance of ground failures and differential ground subsidence. The resulting damage to streets, homes, hydraulic lines, and government facilities has caused economic losses...
Structurally-Controlled Differential Subsidence (SCDS) is the gradual sinking of the ground, characterized by the development of a damage band, terrain discontinuities and collapses, aligned according to the strike of a controlling geological structure. SCDS has been reported since the 1980s in several cities settled on tectonic valleys in central...
Marine oil spills pose significant ecological and economic threats worldwide, requiring effective decision-making tools.

First, a new Sentinel-1 image dataset was created. Nine...
The presence of deep convective clouds is directly related to potential convective hazards, such as lightning strikes, hail, severe storms, flash floods, and tornadoes. On the other hand, Mexico has a limited and heterogeneous network of instruments that allow for efficient and reliable monitoring and forecasting of such events. In this study, a qu...

This study aims to improve the current method of studying potentially toxic elements (PTEs) in urban dust using direct chemical evidence (from dust, rock, and emission source samples) and robust geochemical methods. The provenance of urban dust was determined using REEs and geochemical diagrams (V-Ni-Th*10, Zr vs. TiO2, and Zr/Ti vs. Nb/Y). The geo...
The Villa de Reyes Graben (VRG) is located in the Mesa Central (MC) province and is composed of felsic Oligocene volcanic rocks. In this paper, we present new petrography and whole-rock geochemistry for felsic volcanic rocks to understand their origin, evolution, petrogenesis and their tectonic relation with the MC. Based on geochemical composition...
Groundwater occurrence in semi-arid regions is variable in space and time due to climate
patterns, terrain features, and aquifer properties. Thus, accurate delineation of Groundwater Potential Zones (GWPZs) is essential for sustainable water resources management in these environments. The present research aims to delineate and assess GWPZs in a sem...
In this work, we introduce families of multimodal maps based on logistic map, i.e., families of m-modal maps are defined on an interval I ⊂ ℝ , which is partitioned into non-uniform subdomains, with m ∈ ℕ . Because the subdomains of the partition are not uniform, each subdomain contains a unimodal map, given by the logistic map, that can have diffe...
In the Colorado River Delta, the interaction of tidal currents and sea-bottom sediment formed, in geological times, large-scale seabed patterns known as sandbanks. These patterns are oriented along the delta, almost parallel to the dominant tidal flow, with the bathymetry having an undulating character across the delta. Calculations and analysis sh...
Groundwater has become an alternative water supply for various sectors of the population and the economy, and its extraction is increasing worldwide. The water poverty index (WPI) is a holistic tool that enables the establishment of links between poverty, social marginalization, environmental integrity, water availability and health. The index incl...
The present investigation focused on solving the significance of tidal currents in the sediment resuspension process revealed by satellite imagery in the tidal basin of the Colorado River Delta, located in the northernmost part of the Gulf of California. A depth-integrated finite difference hydrodynamic model, coupled with a suspended sediment tran...
The rapid population growth in urban areas stresses the underlying aquifers in both quantity and quality. The identification of aquifer vulnerability and quality characteristics help decision makers in managing groundwater resources and mitigating potential contamination pathways. For this purpose, the units composing complex aquifer systems should...
In arid and semi-arid regions, unregulated land use changes as a result of poor planning, and the expansion of agricultural and livestock activities increase the risk of desertification and other potentially severe environmental impacts. Several consequences of improper land management practices are soil deterioration and erosion, which may be inte...
Different idealized geometries, resembling shallow tidal-dominated seas with different geographical features like bays, islands, and headlands, were investigated by applying a two-dimensional hydrodynamic-numerical and morphological model. The geometries were exposed to fast oscillatory tidal velocities and unbounded sediment availability. The inte...
Numerical simulations revealed a profound interaction between the severe dust storm of 2007 caused by Santa Ana winds and the Gulf of California.

Recent monitoring techniques employ multiple sources of information for the characterization of the phenomenon to be studied, being the coupling and adjustment of multi-source data one of the first challenges to consider and solve.

Tornadoes are violent and destructive natural phenomena that occur on a local scale in most regions around the world. Severe storms occasionally lead to the formation of mesocyclones, whose direction or sense of rotation is often determined by the Coriolis force, among other factors. In the Northern Hemisphere, more than 99% of all tornadoes rotate...
