This study provides a comprehensive review of the efforts utilized in measurement water quality parameters (WQPs) with focus on total dissolved solids (TDS) and suspended (TSS). The current method used TDS TSS includes conventional field gravimetric approaches. These methods are limited due to associated cost labor, spatial coverages. Remote Sensing (RS) applications have, however, been over past few decades as an alternative overcome these limitations. Although they also present underlying atmospheric interferences images, radiometric spectral resolution issues. Studies WQPs RS, therefore, require knowledge utilization best mechanisms. use RS for retrieval TDS, TSS, their forms has explored many studies using images from airborne sensors onboard unmanned aerial vehicles (UAVs) satellite such those Landsat, Sentinel-2, Aqua, Terra platforms. properties serve inputs deep learning analysis statistical, machine models. Methods retrieve WQP measurements dependent optical inland bodies. While is optically active parameter, inactive low signal–noise ratio. detection visible, near-infrared, infrared bands some process that (usually) co-occurs changes affecting active. revealed significant improvements incorporating approaches estimating WQPs. findings reveal improved spatiotemporal potential effectively detect For effective monitoring we recommend employing correction mechanisms reduce image interference, exploration fusion microwave bands, high-resolution hyperspectral ML models, calibration validation observed data measured methods.

Assessing water quality is necessary to ascertain its viability for domestic, industrial, and agricultural purposes. A total of 48 samples were, respectively, drawn from the Rivers Karawa Iyiaji located in Ezeagu Uzo-uwani which are typical rural areas Enugu State, Nigeria. These were taken two seasons (early rainy season late dry season). Physicochemical properties determined using standard methods. The scaling corrosivity potentials evaluated Larson-Skold index, aggressive Puckorius Ryznar stability index models. Additionally, seven irrigation evaluation criteria, as well spatial distribution maps, used determine suitability river waters purposes interpolate parameters. Major ion chemistry was assessments. physicochemical fell within recommended values.

In recent decades, water pollution has become a major concern, threatening both humans and natural ecosystems. This study aims to analyze seasonal variations in the quality of surface Nador Canal Morocco, using index (WQI) principal component analysis (PCA). Surface samples from 22 sites along canal were analyzed for physical, chemical, heavy metal parameters. The results revealed significant variations, with decreasing summer months, while its generally improved winter. predominant type was Na+-Cl− summer, it mixed Ca2+-Na+-HCO3− WQI values also varied seasonally, an average 113.04 160.6 winter, classifying as unsuitable drinking but suitable irrigation throughout year. are consistent Canal, where showed that there quality. ions like magnesium, sodium, calcium predominantly indicate influences anthropogenic sources. metals nutrients, signaling industrial agricultural runoff, especially prominent.

Impacts of land use/land cover on water quality: a contemporary review for researchers and policymakers

Water Quality Research Journal, Год журнала: 2024, Номер unknown

Опубликована: Апрель 22, 2024

Abstract Few factors are as important in determining water quality land use/land cover (LULC). Many use activities, including agriculture, urban development, mining, and commercial forestry, tend to be sources of diffuse pollution. By contrast, indigenous vegetation can act a sink, thus providing some protection from anthropogenic contamination. Notwithstanding the large body research demonstrating these facts, decision-makers require clear accessible information assist them developing effective management plans that fully cognisant manifold impacts LULC on resources. Reviewing available literature, this article, therefore, offers critical overview typical quality. An strategy for managing highlighted article is maintenance sufficient amount unfragmented natural vegetation, not only within riparian zones but also across catchment areas. However, knowledge gaps identified review indicate further context-specific required determine types minimum vegetative protect resources pollution potential impact landscape fragmentation ability A discussion therefore provided.
