Abstract:

Microplastics have been found in all hemispheres of the world. However, studies on microplastics are mainly conducted in Europe, North America, and East Asia. Few studies are reported in the Southeast Asian region, where a large number of plastic waste is disposed of improperly into the water. This study investigated the abundance and characteristics of microplastics in the surface water of the Chao Phraya River (Thailand), Citarum River (Indonesia), and Saigon River (Vietnam). Samples were collected at urban and estuary zones of these rivers. The numbers of microplastics at the urban zones we

Abstract:

Since the 1990s, under the pressure of socio-economic growth in the Ho Chi Minh City and nearby provinces, the heavy-extraction of groundwater of this area has dramatically increased to meet high water demand for domestic and industrial purposes. Although the groundwater – Saigon River interaction significantly contributes to groundwater reserves, researchers have been less attentive to fully describe and understand the river recharge. This study attempts to explore the impact of groundwater-river interaction to aquifer system due to pumping increase via field seepage and (O18, H2) isotopic me

Abstract The Saigon River, as its economic potential and clusters and industrial parks evolve, is threatened by a high potential for water pollution. The objective is to evaluate the water quality (BOD5 and COD) under the influence of industrial wastewater incidents in the Saigon River using MIKE 21FM model. The results of model calibration and validation have high reliability with NSE values larger than 0.65 for the flow simulation and percentage error values less than 25% for the water quality simulation.

Abstract:

The Surface Water and Ocean Topography (SWOT) mission aims to provide essential data on river width, height and slope in order to estimate worldwide river discharge accurately. This mission offers a powerful tool for monitoring river discharge in dynamic coastal areas, like the Saigon-Dongnai estuary in Southern Vietnam. However, estimating discharge of tidally-influenced rivers using SWOT measurements can be challenging when hydraulic variables have the same order of magnitude as SWOT measurement errors. In this paper we present a methodology to enhance discharge estimation accuracy from SWOT

Abstract:

High concentrations of manganese and iron in the Saigon River are major problems for the water supply in Ho Chi Minh City (HCMC), Viet Nam. To identify their sources and leaching processes, we surveyed water quality along the Saigon River and ran batch leaching tests using soil and sediment samples. Two important leaching processes were identified: acidic leaching from acid sulfate soil (ASS) in the middle reaches of the river, and Mn dissolution and Fe reduction from sediments in the downstream reaches. Low pH caused the concurrent release of Fe and Mn from the ASS. In contrast, anoxia caused

Theses causes have gradually changed the hydraulic regimes of the river system. As a result, saltwater intrusion has become seriously.

After the fall of South Vietnam to North Vietnamese forces in 1975, Vietnam has remained virtually isolated from the rest of the world. With the global political changes of the past 10 years. the Hanoi Government succeeded in reducing Vietnam's international isolation in part by attempting to open the country's door to foreign visitors. The country stretches along the eastern coast of the Indo-Chinese peninsula and is slightly larger than Italy. It is ‘S-shaped’, broad in the north and south and very narrow in the centre (Fig. 1). The country's main cultivated areas are the Red River delta in

Abstract:

Surface water samples in Vietnam were collected from the Saigon River, rural and suburban canals, and urban runoff canals in Ho Chi Minh City, Vietnam, and were processed to enumerate Escherichia coli. Quantification was done through membrane filtration and quantitative real-time polymerase chain reaction (PCR). Mean log colony-forming unit (CFU)/100 ml E. coli counts in the dry season for river/suburban canals and urban canals were log 2.8 and 3.7, respectively, using a membrane filtration method, while using Taqman quantitative real-time PCR they were log 2.4 and 2.8 for river/suburban canal

Abstract:

Abstract. Plastic is an emerging pollutant, and the quantities in rivers and oceans are expected to increase. Rivers are assumed to transport land-based plastic into the ocean, and the fluvial and marine transport processes have been relatively well studied to date. However, the processes controlling the transport in tidal rivers and estuaries, the interface between fluvial and marine systems, remain largely unresolved. For this reason, current estimates of riverine plastic pollution and export into the ocean remain highly uncertain. Hydrodynamics in tidal rivers and estuaries are influenced b

Abstract:

A new species of mud lobster of the genus Thalassina Latreille, 1806 (Decapoda: Gebiidea: Thalassinidae), Thalassina cangioensis sp. nov., is described from mangrove forests of the Cần Giờ Mangrove Biosphere Reserve, located in the Soài Rạp River delta in the downstream of the Dongnai-Saigon River system, South Vietnam. The new species is morphologically mostly similar to T. anomala (Herbst, 1804) in the shape of the rostrum and anterior part of the carapace and the presence of a single median tubercle on pleonal sternites II–V. However, it differs in the strong spinulation on the posterior pa

Abstract:

Vietnam is a country with strengths in agricultural production, rich and valuable agricultural products. Vietnam is often described as a giant boom with two big granaries at both ends, the Red River Delta and the Mekong Delta. Besides, the appropriate weather and climate conditions and fertile soil have created an ideal environment for rice production, thereby making rice a strong export item for Vietnam. In order to boost export rice output, the role of the transport and logistics system is very important. If the transport system is equipped and linked together, it will create added value for

Abstract:

The Thu Thiem road tunnel located deep under the Saigon River is currently ventilated by a system of 12 jet fans that push dust and dirty air out into the environment. These jet fans are driven by Induction Motors (IMs) modeled by mathematical equations on the structural nonlinear dq coordinate system, so the conventional linear controllers partly fail to meet the response requirements. Therefore, this paper proposes the application of the exact linearization control method for the current loop in the Field Oriented Control (FOC) structure of an IM that drives a jet fan of the Thu Thiem road t

Abstract:

Can Gio (CG), a mangrove forest with a dense network of tidal creeks, gradually grew and spread seaward on a coastal platform, which was built since about 8 ka before present (BP). Along with this development, a sand ridge began to form and moved back with the shoreline withdrawal landward in the Late Holocene. This mangrove environment is likely abandoned from the mainland but was, however, the place for settlement of ancient Vietnamese a few centuries BC. The CG mangrove forest was severely destroyed during the American War and was restored since 1980. However, the historical change of the l
