Air emission inventory and application TAPM-AERMOD models to study air quality from 34 ports in Ho Chi Minh City
Tập 2 Số 2 - Trang 97-106 - 2019
The port system of Ho Chi Minh City including 34 ports, serves as the gateway to the South (including the South East and the Mekong Delta) in export and import activities. In which contribute a huge amount of pollutants to the atmosphere in Ho Chi Minh City. The objective of this study is to: (i) Calculating air emissions from ports system in Ho Chi Minh city using the SPDGIZ model which emits a l...... hiện toàn bộ
Evaluate of air pollution dispersion and propose planing scenerios to reduce air pollution for livestock activities in Tan Thanh district, Ba Ria – Vung Tau province
Tập 2 Số 2 - Trang 26-37 - 2019
Livestock is one of the main activities of the agricultural sector in Tan Thanh district, Ba Ria – Vung Tau province. Beside of pollution sources such as waste water, solid waste, livestock activity in Tan Thanh district, Ba Ria - Vung Tau province in recent years has caused air pollution in the livestock area and surrounding area. This research was carried out to evaluate the process of air pollu...... hiện toàn bộ
A separation of plastic debris in Saigon river sediment using a microplastic sediment separator
Tập 5 Số SI1 - Trang SI137-SI146 - 2021
Plastic debris was separated from Saigon river sediment using a microplastic sediment separator (MPSS) for the first time. A separation fluid of ZnCl2 solution (1.6 kg/L) was used to separate lower density materials (floating on the top) from higher density materials (sinking in the bottom). Plastic and plastic-like materials were collected and analyzed by a FTIR spectrometer to determine plastic ...... hiện toàn bộ
Application of multivariate statistical analysis in the assessment of groundwater quality of Tan Thanh district, Ba Ria – Vung Tau province
Tập 1 Số M2 - Trang 66-72 - 2017
In the present study, Multivariate Statistical Analysis (MSA) such as Principle Component Analysis (PCA) and Cluster Analysis (CA) were applied to determine the temporal and spatial variations of groundwater quality in Tan Thanh district, Ba Ria – Vung Tau province. Groundwater samples were collected from 18 monitoring wells in April (dry season) and October (wet season) during the year 2012. Fift...... hiện toàn bộ
Application of material flow analysis (MFA) for estimating the potential of Nitrogen recirculation in closed-ecosystem based catfish farming
Tập 5 Số SI1 - Trang SI1-SI12 - 2021
The purpose of this study is to evaluate and analyze the possibility of nitrogen recirculation when applying a closed eco-system for intensive catfish ponds in the Mekong Delta in accordance with the existing available natural conditions in the local area. A closed ecosystem is proposed for optimizing N emissions from intensive pangasius farming on the basis of closed flows of materials, waste, an...... hiện toàn bộ

Application of GIS and remote sensing to build up a map of environmental geological suitability for residential buildings on Thi Vai river basin
Tập 3 Số 1 - Trang 1-11 - 2019
Geological environment zonation is to divide the areas into relatively homogeneous units based on their natural factors such as hydrology, topography, geology, disasters... to create geoenvironmental units which suit a specific type of exploitation for the purpose of research or regional management. This study presents a process of integrating GIS and remotely sensed data to develop a map of envir...... hiện toàn bộ

Assessment of capacity of using sentinel-1 images in monitoring land subsidence in Ho Chi Minh City
Tập 2 Số 2 - Trang 19-25 - 2019
Permanent Scatterer InSAR (PSInSAR) technique is used commonly to evaluate land subsidence for some cities in the world and the pilot project in Ho Chi Minh City has shown the capability of this technique for mapping land subsidence in the period from 2006 to 2010. The result shows that PSInSAR can be applied to study the land subsidence phenomenon more efficiently than any traditional methods. Ho...... hiện toàn bộ
The Triassic suture between Indochina and Sibumasu blocks - the first discovery of a backarc basin within Vietnam teritory
Tập 1 Số M2 - Trang 14-22 - 2017
A backarc basin represented by a mafic/ultramafic magmatic ophiolitic sequence has been discovered first time within Vietnam territory. Backarc basin/forearc basin and other features of a convergent tectonic system are being considered as a location of the two geological blocks that almagamated together and preferred as a geological suture. The middle Triassic suture resulted from the welding of t...... hiện toàn bộ
3D numerical modeling of flow and sediment transport in rivers and open channels
Tập 3 Số 1 - Trang 23-36 - 2019
Numerical model is a useful tool in studying the flow and sediment transport, change in river bed and is built on solving governing differential equations. Numerical model has many different levels and three-dimensional model is the highest level, allowing detailed simulation of flow and sediment transport process in 3D space. The paper presents a method calculating three - dimensional flow and se...... hiện toàn bộ
