Delineation and Morphometric Characterization of Small- and Medium-Sized Caspian Sea Basin River Catchments Using Remote Sensing and GISs

Water, Journal Year: 2025, Volume and Issue: 17(5), P. 679 - 679

Published: Feb. 26, 2025

This investigation endeavors to demarcate the boundaries of small- and medium-sized river catchments within Caspian Sea drainage basin, with a specific focus on Northeastern Caucasus, Azerbaijan, Iran regions. A multi-faceted approach was employed, incorporating various remote sensing methods select key areas, including Sunzha, Sulak, Ulluchay, Karachay, Atachay, Haraz, Gorgan rivers. Subsequently, geoinformation systems (GISs) topographic maps were utilized determine morphometric characteristics these catchments, accompanied by an assessment accuracy data. The aim this study is evaluate suitability digital elevation models (DEMs) spatial resolution 30 m per pixel (including ASTER DEM, ALOS NASADEM, Copernicus SRTM DEM) 90 (Copernicus DEM for delineating basin catchments. For DEMs that successfully accurately delineated watershed boundaries, basins calculated. research has yielded novel findings regarding (area, perimeter, ruggedness catchment line (roundness coefficient), maximum height, minimum average height slope surface, length main watercourse, shape parameter (catchment elongation coefficient, slope, width basin) individual mountainous rivers in Iran, aforementioned serving as exemplars. practical significance results lies fact such detailed have been obtained first time, their clarified (burned out according DEMs), which can serve basis decision-making processes contribute development operational environmental monitoring state

Heavy Metals in Soils of the Fatala River Basin (Republic of Guinea)

Revista de Gestão Social e Ambiental, Journal Year: 2024, Volume and Issue: 18(9), P. e08309 - e08309

Published: Aug. 29, 2024

Objectives: The objectives of this research include assessing the concentrations heavy metals and trace elements in Fatala River basin (Republic Guinea), identifying primary sources these pollutants, analyzing their migration patterns, evaluating ecological health impacts, contributing to development effective pollution mitigation strategies. theoretical framework is grounded understanding anthropogenic impact on soil, role soil as a natural filter, associated risks, application Geographic Information Systems (GIS) for detailed analysis. Theoretical Framework: Pollution from presents significant threat environmental health, situation that has been exacerbated with expansion mining industrial activities. Despite advancements technology aimed at reducing contamination, many regions, particularly developing countries, continue experience unchecked due lack safeguards. This study focuses Republic Guinea, region heavily impacted by extensive activities growth population settlements, which have led accumulation soil. Methods: In analysis samples collected river basin, determination metal element content was performed using an inductively coupled plasma mass spectrometer, specifically PlasmaQuant MS Elite S-NR:11-6000ST043 instrument. spatial distribution within mapped ArcGIS 10.8 software.To create comprehensive representation distribution, mathematical interpolation values carried out Interpolation tool (Spatial Analyst Tools) 10.8. inverse distance weighted (IDW) technique employed purpose. To assess extent severity contamination area, three key parameters were calculated: hazard coefficient Ko, concentration (Kc), total index. These provide quantitative measure levels risks region. Results discussion: indicates certain elements, such silver (Ag), arsenic (As), beryllium (Be), cadmium (Cd), selenium (Se), significantly exceed regulatory limits, posing serious ecosystem whole. categorized into four groups based levels, ranging those acceptable limits exceeding them. Cadmium (Cd) highlighted its concentrations, some instances are 14 times above standard limits. It also emphasizes importance further studies identify origins effects basin's ecosystem. conclusion strategies reduce harmful including implementation system regulating measures land reclamation. Implications research: map index constructed. revealed most territory belongs moderately dangerous category, characterized increase overall morbidity rate. Originality/value: authors stress conducting additional research, implementing normalizing pollutant detrimental environment public health. serves valuable contribution implications highlights need ongoing efforts address issue.

The aim of this study is to identify the main factors anthropogenic impact and indicators landscape transformation in Fatala River Basin Republic Guinea. Our fieldwork Boke Kindia regions was source materials data. ecological situation nine key plots were characterized. These make up a representative series transformed natural landscapes. We complemented our with Landsat satellite image analysis. learned that are systematic burning vegetation, mechanical disturbances soil vegetation cover, depletion fertile topsoil, grazing, littering household waste. deforestation, changes mechanically disturbed lands. identified five stages agro-landscape development, starting from clearing plot by (stage I) ending completion agricultural activity its abandonment restore topsoil V). limiting nature management elevation differences, rapid restoration rocky/gravelly substrate. It possible landscapes large or hard-to-reach using images. Thus, quasi-natural can be based on lower surface temperature relative surrounding normalized difference index (NDVI) moisture (NDMI) could useful for identifying pasture within tropical forest long-term data series. revealed tendency deterioration middle upper parts Basin, while cover being restored part basin.
