Application of groundwater quality index (GWQI) and principle component analysis (PCA) to assess the groundwater quality of Pleistocene aquifer in Tan Thanh district, Ba Ria – Vung Tau province
Tập 2 Số 2 - Trang 107-115 - 2019
This research applied the groundwater quality index (GWQI) and principal
component analysis (PCA) for assessing pollution levels and factors effecting
groundwater quality of Pleistocene aquifer in Tan Thanh district, Ba Ria – Vung
Tau province. Seventeen wells were colected in April (dry season) and October
(rainy season) during 5 years (2012-2017). Nine parameters of water (pH, TDS, độ
cứng, Cl-,...
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...
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...
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 ...
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.

Analysis of riverbank changes in Ho Chi Minh city in the period 1989 – 2015
Tập 2 Số 2 - Trang 80-88 - 2019
The objective of this study was to analyze the changes of riverbanks in Ho Chi
Minh City for the period 1989-2015 using remote sensing and GIS. Combination of
Modified Normalized Difference Water Index (MNDWI) and thresholding method was
used to extract the river bank based on the multi-temporal Landsat satellite
images, including 12 Landsat 4-5 (TM) images and 2 Landsat 8 images in the
period 198...
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...
Reuse shrimp pond sedimentation to produce organic fertilizer in industrial scale
Tập 5 Số 1 - Trang 273-283 - 2021
The purpose of this study is to reuse shrimp pond bottom sludge for
industrial-scale organic fertilizer production, to reduce emissions from shrimp
farming, and protect the environment. Sludge from the bottom of shrimp ponds is
collected through channel settling with a filter net of 0.25 millimeters in
size, rainwater is used to wash the salt content in the sludge of shrimp ponds.
When the EC (Ele...

Developing IDF curve of extreme rainfall at Tan Son Hoa station for the period 1980-2015
Tập 1 Số M2 - Trang 73-81 - 2017
Recently, the Intensity – Duration – Frequency (IDF) relationship of extreme
rainfalls in a local area is usually investigated to provide accurate required
data for calculating, planning, and developing urban drainage systems,
especially in the context of climate change. Traditionally, IDF curves are
computed based on a statistical method for analyzing the frequency of occurrence
or non-occurrence...
Optimizing Electro-Fenton process for removal of atrazine from aqueous solutions using Taguchi method
Tập 5 Số 2 - Trang 369-376 - 2021
The purpose of this study is centered on the removal of atrazine, one of the
popular organochlorines in Vietnam, from an aqueous solution, using an electro
Fenton process with iron and carbon plated steel electrodes at a batch electro
reactor. This study had applied the Taguchi method, one of the most
uncomplicated cases of design of experiments involving the minimum number of
experiments to be pe...
