HIGH ARSENIC CONCENTRATION IN GROUNDWATER RELATED TO SEDIMENTARY FACIES IN THE MEKONG RIVER DELTA, VIETNAM
Vietnam Journal of Earth Sciences - Tập 38 Số 2 - 2016
Nguyen Van Lap, Ta Thi Kim Oanh*
Arsenic (As) contamination in groundwater has been recognized in the Mekong River Delta (MRD) since 2001, especially in Dong Thap and An Giang provinces. The investigations were carried out during 2008-2009 and from 2012 to present. The investigations of As distribution in groundwater and sediments were based upon the field, and laboratory analyses using field kit (Hironaka, 1998) and AOAC laborat...... hiện toàn bộ
Monitoring spatial-temporal dynamics of small lakes based on SAR Sentinel-1 observations: a case study over Nui Coc Lake (Vietnam)
Vietnam Journal of Earth Sciences - Tập 24 Số 3 - 2022
Son Tong Si, Binh Pham Duc
For the first time, this study estimates the variation of surface water extent of Nui Coc Lake located in Thai Nguyen province in North Vietnam at high spatial (20 m) and temporal resolution (bi-weekly). The classification methodology was developed based on the use of the Otsu threshold algorithm on the histogram of the backscatter coefficient of the SAR Sentinel-1 signal. Totally, more than 150 S...... hiện toàn bộ

Earthquake affects subsidence in Jakarta using Sentinel-1A time series images and 2D-MSBAS method
Vietnam Journal of Earth Sciences - Tập 45 Số 1 - 2023
Mokhamad Yusup Nur Khakim, Takeshi Tsuji, Supardi Supardi
Excessive groundwater extraction has been well known as the main factor causing land subsidence in several cities in Jakarta Basin, Indonesia. This area is surrounded by active geological structures and has thick sediments. This study emphasizes the impacts of earthquakes on subsidence over Jakarta and its surroundings by using the Sentinel-1A images and 2D-MSBAS (Multidimensional Small Baseline S...... hiện toàn bộ
