A methodology to estimate surface water quality using remote sensing is presented based on Landsat satellite imagery and in situ measurements taken every six months at four separate sampling locations a tropical reservoir from 2015 2019. The uses the Box–Cox transformation model normalize data three parameters: total organic carbon (TOC), dissolved solids (TDS), chlorophyll (Chl-a). After transformation, mathematical was generated for parameter multiple linear regression correlate normalized...

Este estudio analiza las variaciones espaciales y temporales en la calidad del agua de acuíferos Sinaloa, centrándose parámetros fisicoquímicos clave. Los niveles pH se mantuvieron un rango saludable, indicando condiciones ligeramente alcalinas. Sin embargo, los sólidos disueltos totales (SDT) mostraron alta variabilidad, especialmente el acuífero Río Mocorito (ARM), sugiriendo posible contaminación. nitratos, cloruros sulfatos fueron elevados ARM, reflejando influencia actividades agrícolas...

Este estudio evalúa la calidad del agua acuífero Río Sinaloa mediante un enfoque integral que incluye análisis espacial y temporal, así como correlaciones entre parámetros fisicoquímicos, microbiológicos e iónicos. El permitió identificar variaciones en distribución de contaminantes distintos puntos muestreo, vinculando estos patrones con actividades antrópicas. realizado a lo largo 10 años (2012-2022), reveló tendencias fluctuaciones los calidad, destacando eventos contaminación...

The knowledge of the soil quality plays a vital role in agricultural sector. Despite its importance, there is scarce scientific information concerning this regard. objective research to develop methodology identify and select most appropriate indicators Soil Quality Index (SQI) region with high activity. For conformation, descriptive statistical analysis Pearson correlation matrix were performed that showed greater variation identified using Principal Components Analysis (PCA). A sensitivity...

Abstract The planimetric and altimetric accuracies of the Digital Elevation Model (DEM) obtained from Unmanned Aerial Vehicle (UAV) depend on some photogrammetric parameters such as flight height, speed, and/or ground sample distance. In last few years, study computer vision algorithms has increased focusing their importance reconstruction process for land surface mapping. According to this, main goal this paper was evaluate performance different processing software, Open Drone Map (ODM),...

The use of whey as a natural culture medium to produce hydrolysates with antimicrobial from Bacillus clausii is the objective this research. fermentation process was carried out at 25 ℃ for five days, where proteolytic activity, soluble peptides quantification, and activity using disc diffusion method were determined every day. fermented reached values ​​of between 90 260 U ml-1 production 100 2070 µg ml-1. maximum ​​were after three days all determinations. In addition, inhibition zone...

Agricultural activities are highly related to the reduction of availability water resources due consumption freshwater for crop irrigation, use fertilizers and pesticides. In this study, quality Adolfo López Mateos (ALM) reservoir was evaluated. This is one most important reservoirs in Mexico since stored used mainly irrigation productive agricultural region. A comprehensive evaluation carried out by analyzing behavior 23 parameters at four sampling points period 2012-2019. The analysis...

Abstract The dynamics of water temperature, dissolved oxygen and total solids concentrations in Aguamilpa Reservoir was analysed by considering horizontal column variations. reservoir model, CE‐QUAL‐W2, used to simulate the temporal variations calibrated with data gathered every 2 months from June 2008 2009. Temperature depth profiles indicated a typical asymmetry reservoirs exhibiting large stratification lower part near dam. Dissolved concentration exhibited some degree anoxia bottom...

Abstract A statistical assessment was used to assess if a tropical reservoir had reached stable condition, permitting the use of water quality models predict dynamics system under different climatic or management scenarios. This approach applied Aguamilpa Reservoir in western Mexico, one largest reservoirs world. Water data collected by National Commission, and hydrological from Federal Electricity Commission period January 2000 December 2007 served as base. Time‐series analysis identified...

Electrochemical techniques have been used for the discolouration of synthetic textile industrial wastewater by Fenton's process using a parallel plate reactor with reticulated vitreous carbon (RVC) cathode. It has shown that RVC is capable electro-generating and activating H2O2 in presence Fe(2+) added as catalyst stainless steel mesh anode material. A catholyte comprising 0.05 M Na2SO4, 0.001 FeSO4.7H2O, 0.01 H2SO4 fed oxygen was to activate H2O2.The anolyte contained only 0.8 H2SO4. The...

The present study focuses on identifying and describing the possible proximate underlying causes of deforestation its factors using combination two techniques: (1) specialized consultation (2) spatial logistic regression modeling. These techniques were implemented to characterize process qualitatively quantitatively, then graphically represent from a temporal point view. area is North Pacific Basin, Mexico, 2002 2014. map difference technique was used obtain land-use vegetation maps. A...

Groundwater is an important source of fresh water in the world. However, excessive extraction and increasing pollution represent a major challenge for sustainability Mexico. Nowadays, since quality changes aquifers are not noticeable, aquifer monitoring assessment imperious. In this study, Cuernavaca was evaluated using database 23 parameters 4 sampling points from 2012 to 2019. The spatial behavior variables described by interpolation. temporal evaluation groundwater carried out through...
