“…The process of setting up the model involved several key steps: (1) Gathering data required for the model, such as the flow, water levels, the concentration of salt, technical details of tidal sluice gates, and the shape of the river; (2) Constructing the river network with sluice gates that will be used for input data in the model; (3) Establishing the HD module, fine-tuning and verifying the water levels and discharge; (4) Establishing the AD module, calibrating and verifying the salinity concentrations; (5) Formulating different scenarios for operating tide gates; (6) Modeling and evaluating the propagation of saltwater intrusion based on predefined scenarios.…”

“…Furthermore, the model's reliability has been demonstrated in numerous studies focusing on hydraulic simulation and the spread of substances, particularly saltwater intrusion, in both domestic and international river systems. Notable studies include the Sebou estuary area in Morocco [3], the Kobadak-Sibsa river system in Bangladesh [4], the Shatt Al-Arab River in Iraq [5], the Cubatão estuary area in Brazil [6], the lower Mekong river region, and the Saigon-Dong Nai River system in Vietnam [7,8].…”

This study aims to evaluate salinity intrusion propagation in Ho Chi Minh City under the operation of six tidal sluice gates, namely, Ben Nghe, Tan Thuan, Phu Xuan, Muong Chuoi, Cay Kho, and Phu Dinh by utilizing the HEC-RAS model. The outcomes during calibration and validation procedures underscore the high performance of the HEC-RAS model in simulating salinity intrusion over the study area. In particular, R2 and NSE values were higher than satisfactory thresholds of 0.80 for water level and discharge simulations and 0.50 for salinity concentration simulations. Based on the calibrated HEC-RAS model, this study examined the potential influences of sluice gate operations on salinity distribution under different scenarios. Results indicate that salinity concentration would exhibit increasing trends when operating Ben Nghe and Tan Thuan sluices, while the closure of the Phu Xuan and Muong Chuoi sluices would cause a reduction in the salinity concentration within the areas enclosed by these sluices. In addition, the operations of the Cay Kho and Phu Dinh sluices would lead to decreases and increases in salinity concentration in the upstream and downstream areas of each corresponding sluice gate, respectively. Moreover, when closing six sluice gates simultaneously, the salinity concentration inside and outside the sluice gates would decrease and increase, respectively. In general, these findings indicate that salinity concentration and spatial distribution are significantly influenced by the location and structure of each tidal sluice gate.

“…Seawater can also travel upstream along rivers, thereby increasing the salinity of river water. Under the conditions of sea-level rise, the sea level, flow velocity and tidal strength increase, which exacerbates seawater intrusion in river areas [69]. In recent studies, more attention has been paid to research on the effect of sea-level rise on seawater intrusion.…”

With the rapid development of urbanization around the world, the sea-level-rise problem is gaining more and more attention in the 21st century. Sea-level rise is the result of a combination of climate-related factors, structural factors and human activities. Recent studies related to the contributions of these factors to sea-level rise are reviewed and analyzed in this paper. The results suggest that the melting of glaciers and ice sheets have contributed the most to sea-level rise and will continue to be the dominant factor in sea-level rise for the following decades. As sea-level rise becomes an increasingly serious problem, geological disasters related to sea-level rise are also gaining more attention. To better understand the effect of sea-level rise on geological disasters, relevant issues including storm surges, seawater intrusion, the loss of coastal wetland, seismicity, seismic liquefaction and submarine mass failure are further reviewed and highlighted. In response to the risks of those disasters caused by sea-level rise, some disaster mitigation measures are proposed, and in the end, the quantitative disaster assessment concept based on resilience is introduced to the coastal urban system, to assess its ability to resist and recover from geological disasters due to the sea-level rise.
