1. Vu Thi Hoai Thu, Toshinori Tabata, Kazuaki Hiramatsu, Trieu Anh Ngoc, Harada Masayoshi, Impact of gate operating modes of sea dikes on hydrodynamic regime and inundated area in Can Gio Bay, Coastal Engineering Journal, 10.1080/21664250.2019.1579460, 61, 2, 171-186, 2019.05, [URL], Ho Chi Minh City gets severely inundated by upstream flooding and a combination of rising spring tides and rain, owing to the combined impacts of rapid urbanization and sea level changes. A sea dike to close Can Gio Bay has been proposed to regulate storage and control water levels in the drainage and sewer system of Ho Chi Minh City. However, this proposed sea dike and different gate operating modes could significantly change the hydrodynamic regime in Can Gio Bay. In this study, a two-dimensional hydrodynamic model was developed to assess changes in the hydrodynamic regime after construction of the sea dike, including fluctuations in the inundated areas in Can Gio Bay mangrove forests. The results show that sea dike construction is an effective solution for controlling water levels and reducing inundation, especially considering a sea level rise scenario in the year 2050. Further, the gate operation mode also affects the effectiveness of inundation reduction, which is approximately 10% better than the same sea dike type without gate operation. However, the sea dike was less effective in a sea water level rise scenario in 2100 for all scenarios..

Vu Thi Hoai Thu, Toshinori Tabata, Kazuaki Hiramatsu, Trieu Anh Ngoc, Harada Masayoshi, Effects of sea level rise and sea dike construction on the downstream end of the Saigon River Basin (Can Gio Bay), Japan Agricultural Research Quarterly, 10.6090/jarq.52.229, 52, 3, 229-239, 2018.01, [URL], Located at the downstream end of the Dong Nai-Saigon river basin, near the mouth of the Saigon River, which is known as the "green lungs" of Ho Chi Minh City (HCMC) due to the ecosystem functions of the Can Gio mangrove forest, is a very complex hydrodynamic and geomorphic region with crossing estuaries, forming the so-called Can Gio Bay. Given its flat, low-lying topography, this area is strongly influenced by two main factors: (1) upstream flooding and (2) tidal regimes. The historical flood event of 2000 indicated that the downstream region of HCMC suffers from serious flooding, and that the Can Gio area is the worst affected, with approximately 90% of its area being inundated. This research aims to investigate the impact of tides and inflows in Can Gio Bay in the context of sea level rise and a sea dike structure connecting Go Cong to Vung Tau. A two-dimensional hydrodynamic model combined with a wetting and drying scheme is used to determine the locations of inundated areas. This research also shows how sea level rise and upstream flows cause flooding in Can Gio Bay, and identifies the negative and positive impacts of sea dike construction on Can Gio Bay..

Toshinori Tabata, Kodai Nakashima, Kazuaki Hiramatsu, Harada Masayoshi, Investigation of the effects of human activities using multi-box ecosystem model in the Ariake sea, Japan, 21st Congress of International Association for Hydro-Environment Engineering and Research-Asia Pacific Division: Multi-Perspective Water for Sustainable Development, IAHR-APD 2018, 2018.09, In this research, the effect of human activities has been investigated in the Ariake Sea located in Kyushu Island. Japan. The Ariake Sea has been suffering from environmental degradation for more than a decade with unstable fisheries productivity. Therefore, it is important to understand the change of environmental characteristics in the Ariake Sea quantitatively. Moreover, it is concerned that the fertilizer applied for the aquaculture is effecting to the ecosystem in the sea. Also, since nutrient loading from rivers are so high that red tide or anoxic water mass occurs every year, it is significant to evaluate the effect of nutrient load to the sea. Therefore, in order to characterize the coastal environment and investigate the effect of human activities, Muti-Box Ecosystem model have constructed to simulate the water quality items in the Ariake Sea. The sea was divided into 12 boxes. Each box is comprised of three layers which is water, oxidative bottom and reductive bottom layer. Simulation period was set from 1st January 2000 to 31st December 2012. The model reproduced the water quality items well. Then, the model calculated with two different scenarios about the fertilizer application to the aquaculture and nutrient load from the river. The result showed that the fertilizer for the aquaculture has no effect to the coastal ecosystem and coastal environment would improve if the nutrient load reduced by half..
