Preliminary assessment on the microplastic contamination in the atmospheric fallout in the Phuoc Hiep landfill, Cu Chi, Ho Chi Minh city
Abstract: Microplastic pollution has become a global issue in recent years. Since the early 2000s, scientists have investigated the occurrence of microplastics (MiPs) in the environment. While research on marine MiPs is more advanced at present, there are immense gaps of knowledge regarding continental MiPs. Airborne MiPs are one source of M...

The zoning of surface water quality by WQI index in the Tien Giang province, Vietnam
Abstract: According to Decision No. 711/QD-TCMT of the Ministry of Natural Resources and Environment, the water quality index (WQI) formula has been adjusted toward localisation, particularly, for the Nhue Day and Cau river basins. In this work, the WQI formula was amended by adjusting the weights of the components of surface water quality. ...

Assessing existing surface water supply sources in the Vietnamese Mekong delta: case study of Can Tho, Soc Trang, and Hau Giang provinces
Abstract: In the recent past, the quality of surface water for domestic use in the Vietnamese Mekong delta (VMD) has been seriously affected by severe water pollution and intense saltwater intrusion. This study aims to assess existing surface water sources in the provinces of Can Tho, Hau Giang, and Soc Trang. By assessing the existing salin...

Application of EBN to predict the dry discharge in Ta Trach river, Thua Thien Hue province, vietnam
Abstract. Predicting dry season flows play an important role in distributing and managing water resources. Hydrological models can predict the flow with good quality results for the flow in large basins, mainly affected by rainfall and buffer surface properties. The discharge is usually very small flow in the dry season and influenced by many fa...

Variation in morphology of the Red river and Duong river near Hanoi from 2000 to 2018
Abstract: In recent years, the construction of upstream reservoirs and the extraction and structural construction activities on the river banks and beds have caused downstream changes in river morphology and hydrological regime of the Red river system, which has especially accelerated from 2000 to 2018. These dramatic variations have signifi...

Assessment of phosphorus release from alluvial sediments using single extraction: A case study in Can Gio, Southern Vietnam
Abstract: Sediment-water interaction is a complicated process; hence, it is essential to know the potential mobility of an element from sediment to the aquatic environment. In this study, the potential mobility of phosphorus (P) in sediment from Can Gio was investigated. Three single extractions were applied including a mild salt (NH4Cl), an...

Using a numerical model with moving boundary conditions to study the bed change of a Mekong river segment in Tan Chau, An Giang, Vietnam
Abstract: Numerical models that calculate bed change are becoming increasingly popular because of their longterm forecast projections and their ability to identify causes of bed change. However, the reliability of the simulation results depends on the length of the data series and the algorithms in the model, in which the boundary condition m...
