Microplastic pollution in tropical urban rivers has become an increasing environmental concern due to rapid urbanization, inadequate waste management, and hydrological transport processes. This study investigated the occurrence, characteristics, and spatiotemporal distribution of microplastics in the Can Tho River, Vietnam, along an urban– peri...

Microplastics (MPs) (<5 mm) are hydrophobic and can't be easily degraded. These particles accumulate due to the excessive discharge of plastic waste from domestic and industrial sources, along with several toxic compounds attached to their surface, are also being deposited in environmental matrices, hampering the sustainable environment and human...

Salinity intrusion has become a critical threat to agricultural stability and water resource management in the Vietnamese Mekong Delta (VMD), particularly in coastal regions. This study evaluates the efficacy of the Long Short-Term Memory (LSTM) neural network, a sophisticated deep learning (DL) architecture, for predicting salinity concentrations...

Drought is a recurrent hazard in the Vietnamese Mekong Delta (VMD), with major implications for agriculture, water resources, and rural livelihoods. This study assesses drought variability in Kien Giang Province, Vietnam, from 1992 to 2024 using two multiscale indicators: the Multivariate Standardized Precipitation Index (MSPI) and the Multivariate...

Suspended sediment concentration (SSC) and sediment flux (SF) are critical indicators of sediment delivery in the Lower Mekong and underpin deltaic geomorphic stability and ecosystem services. With recent evidence of declining sediment supply caused by upstream regulation and intensive in-channel extraction, there is a pressing need for...

Fluvial sediment fluxes are reshaping coastal water colour, geomorphology, and ecological processes, yet schemes based on single-river loads or shoreline change may miss land-sea responses. We combine SSC records from 19 river stations across nine Chinese basins (2004-2024) with MODIS reflectance to characterize clearing, brightening, regional...

Changes in land use over space and time are key drivers of water pollution. However, current studies on landuse–water-quality relationships in small watersheds are insufficient to support regional development. Comparative research across large-scale watersheds can better inform water environmental protection, yet such studies remain limited. This...

This research focuses on the global issue of heavy metal (HM) contamination in coastal systems and provides the first baseline investigation of the surface sediments in Tiruchendur Taluk, southern Thoothukudi, while evaluating potential sources and associated ecological risks. A total of 25 sediment samples were analyzed for particle size...

The intensification of agriculture, coupled with unregulated fertilizer application and groundwater overexploitation, has led to widespread nitrate (NO3􀀀 ) contamination in many agrarian regions, including the Malwa region of Punjab, India. This study employs the Water Evaluation and Planning (WEAP) system to simulate the spatio-temporal evolution...

Plastic waste in Indonesia threatens environmental sustainability and health. This study explores waste bank as a social innovation based on the 3R principle, as a means of education, behavior change in waste management, and the implementation of the circular economy. Aims: This study aims to identify and describe the practices and reasons of...
