Assessment of urban flooding in Yen Hoa - Hoa Bang area, Cau Giay, Hanoi
ABSTRACT Hoa Bang street is known as one of flooding hot spots in Hanoi with 30 inundated times during last 4 years. In 2019, a new conduit has been set up to drain the water from Hoa Bang street to To Lich River. However, the flooding situation has not been significant improved. Therefore, it is necessary to evaluate the capacity of the dra...

Assessing the impacts of the changes in the upstream flow and sea level rise due to climate change on seawater intrusion in Ho Chi Minh city using the HEC - RAS 1D model
ABSTRACT The aim of this study was to assess the impacts of the changes in upstream flow and sea level rise due to climate change on seawater intrusion in the Sai Gon and Dong Nai Rivers in Ho Chi Minh City. The HEC-RAS model was used for simulating the salinity intrusion. The results of model calibration and validation indicated that the HEC-R...

Artifical neuron network for flood forecasting as inflow of pleikrong reservoir in Poko river
ABSTRACT In Vietnam, modern and small hydropower reservoirs play an important role in socio-economic development. However, the effective operation of such reservoirs based on the argument of the release function and expected future inflow is one of the most important variables that the operators will reply on to control such release. In other w...

Application on shallow neuron network (SNN) in flood forecasting, case study in Vu Gia Thu Bon river basin
Abstract: Flood forecasting is one of the most important thing for flood prevention. Upto date, there are many techniques that can be used for this work, from simple ones like linear regression model (AR, ARX, ARMA, etc.) to very comlex models like hydrological and hydrodynamic models). Recently, Artificial Inteligent (AI) become an cleve approa...

Application of remote sensing techniques for analyzing operation of upstream reservoirs in transboundary river basins of Vietnam
Abstract: Operation of upstream reservoirs in transboundary river basins strongly influences water resources in Vietnam. However, due to the lack of observation data, it is difficult to have sufficient information on their operation. In that context, remote sensing with a global coverage has a great potential to provide this information. This st...

Application of ecosystem modeling of phytoplankton size structure using stella to analyze asan bay coatal estuary
ABSTRACT The phytoplankton dynamics considering size structures were investigated in Asan Bay. The contribution of netphytoplankton (>20µm) was high in spring, whereas contributions of nanoplankton (2<20µm) increased from summer to winter. The enrichment of PO43- in winter and the increase of radiance in spring often appeared to control phy...

Application of constructed wetland for advanced treatment of industrial wastewater
Abstract: An experimental study to use a pilot vegetated submerged bed (VSB) wetland for the advanced treatment of effluent from the central wastewater treatment plant (CWWTP) of an industrial zone was carried out. The pilot VSB wetland included reeds (Phragmites australis), cattail (Typha orientalis), and blank cells in parallel. The constr...
