Working with Quang Nam province and Da Nang City for coastal hazards management

On 24 and 25 May 2020, in the series of activities under the project entitled “Towards Risk Reduction and Resilience to Coastal Hazards: A Big Data Analytics Approach”, a research group from Thuyloi University (TLU), Dong Nai University (DNU), and Duy Tan University (DTU) has collaborated in reviewing and proposing a proper solution for risk reduction and resilience to coastal hazards in Hoi An, Quang Nam province and discussing further cooperation in the field at the Central Vietnam Institute of Water Resource (CVIWR) in Da Nang province.

The visit began by having a meeting with the representatives of the College of Technology, Economics and Irrigation Central (CTEIC) in Hoi An, Quang Nam (Fig. 1). The meeting provided the research groups of TLU, DNU, and DTU with a brief review of coastal hazards in Hoi An and related promising solutions before onsite investigation presented as below.

It is known that since 2014, strong waves and tropical storms have caused severe erosion on Cua Dai beach, Hoi An – the ancient town on the list of UNESCO-recognized heritage sites at risk from climate change. A large region of Hoi An is about two meters above sea level, making it vulnerable to sea-level rise and storm surges. The rising sea levels have caused serious coastal erosion at Cua Dai beach in Hoi An. It is also known that between 10 and 20 meters of land to erosion are lost annually (Fig. 2). Local authorities spent around VND70 billion ($3.08 million) building a new embankment, installing iron pilings and dumping sand in the area to save Cua Dai as shown in Fig. 3. Recently, workers and machines have been working night and day to establish new dumping sand embankments (Fig. 4).

On the visit, we also went to the Dinosaur Island – an unexpected raising island in Hoi An for onsite investigation as shown in Fig. 5. It is worth checking the erosion and the establishment of the Dinosaur Island together with the other erosion at Cua Dai beach since it will help us obtain the whole picture of coastal hazards in Hoi An for future research directions.

In addition, we had an important meeting at the Central Vietnam Institute of Water Resource (CVIWR) in Da Nang province (Fig. 6). At the meeting, after listening a detailed report given by a research group led by Dr. Hoang Ngoc Tuan (Director of CVIWR) on the extreme landslide situations in Nam Tra My, Bac Tra My, and Phuoc Son districts in Quang Nam province (Fig. 7), Dr. Nguyen Dinh Long and Prof. Nguyen Trung Viet presented the proper solution for risk reduction and resilience to the erosion and landslide disasters (Fig. 8). Further discussions at the meeting on the aforementioned problems between CVIWR, TLU, DNU, and DTU have proposed a more convincing and efficient solution for applying IoT and big data analysis approach to risk reduction and resilience to coastal hazards and erosion as well as landslide disasters.

Finally, we attended a seminar on “Correcting Truong Giang River and Zoning Ky Ha Port in Quang Nam” as shown in Fig. 9. The seminar was hosted by Dr. Le Thanh Tri (Chairman of Quang Nam People’s Committee) and Prof. Nguyen Trung Viet (Vice President of TLU), for the purpose of planning the navigation channel in Cua Lo zone as well as building a closed network of experts in risk reduction and resilience to coastal hazards, to gain a sustainable economic and social development in Quang Nam. At the seminar, we were glad to work with the local representatives of Department of Transport, Department of Agriculture and Rural Development, Chu Lai Open Economic Zone, Vietnam Academy for Water Resources, and Construction Consultation Joint Stock Company for Maritime Building, who suggested many useful guidelines to maximize the achievements of the project.
