澳大新語 • 2021 UMAGAZINE 24 37 專題探討 • TOPIC INSIGHT Offshore Civil Engineering Macao is a coastal city. There have been many major marine projects in recent years and there will be more in the coming decades. These include the construction of sea bridges and underwater tunnels, as well as land reclamation. These major infrastructure projects must be well managed and maintained in order to ensure safety, extend their service life, and provide a real impetus to economic and social development. Prof Hannah Zhou Wanhuan, head of the Department of Civil and Environmental Engineering and interim head of the Centre for Regional Oceans, says she and her colleagues plan to focus on systematic monitoring, life cycle assessment, and smart maintenance of coastal buildings and sea-crossing clusters, and to develop smart monitoring systems and professional simulation analyses to address a variety of disastercausing factors, such as major natural hazards like typhoons, durability of marine structures, and settlement of reclaimed land. Their work aims to provide life cycle risk assessment and maintenance decisions for the safety of major infrastructure projects and civil engineering works in service. As all of the above-mentioned projects affect water quality, marine ecosystems, and marine biodiversity, the university is also working with government departments and companies to evaluate the actual effectiveness of marine projects and to promote research synergies in the fields of offshore environmental ecology, urban natural disaster prevention and control, and ocean engineering. The Guangdong-Hong Kong-Macao Greater Bay Area (GBA) is one of the largest port areas in the world. As one of the core cities in the GBA, Macao is taking a step further towards sustainable development by increasing its efforts to protect the marine ecosystem and optimise the use of marine resources. At the University of Macau (UM), researchers are working with various institutions in the field of regional oceanology, focusing on offshore civil engineering, the marine environment and ocean ecology, as well as marine disaster prevention and control. Increased Investment in Regional Oceanology In 2015, the State Council demarcated a maritime space of 85 square kilometres under the control of the Macao Special Administrative Region, bringing new opportunities for maritime activities and marine research in Macao. In view of this, the university has made regional oceanology an important part of its ‘3+3+3+3’ strategic research blueprint. Researchers are working on cutting‑edge topics to help the government address challenges in the use of the ocean, marine disaster prevention and control, and marine environmental protection. In August 2021, with the support of the Macao Marine and Water Bureau, 23 researchers from UM, Hong Kong University of Science and Technology’s (HKUST) Centre for Ocean Research in Hong Kong and Macau, and Xiamen University launched their first summer marine research expedition to the Greater Bay Area. At the launch ceremony, UM Rector Yonghua Song said: ‘We hope to help the Macao SAR government address the challenges in the use of the ocean, in the prevention and control of marine disasters, and in the protection of the marine environment. So we have identified regional oceanology as a key research area. We train young researchers and focus on emerging topics with an interdisciplinary approach.’ 區域海洋研究中心的重點研究內容框架 The research framework of the Centre for Regional Oceans 海洋多圈層動力與環境調節機制 Ocean Multi-Sphere Dynamics and Environmental Regulation Mechanism 濱海城市自然災害與工程 Natural Disasters and Offshore Engineering in Coastal Cities 濱海環境治理與資源開發 Engineering System Simulation and Maintenance Multi-scale dynamic processes in South China Sea-Shelf-Estuary Sediment transport and evolution of coastal morphology Water pollution capacity and storage-retention mechanism Pollutant multi-phase transformation and transport Storm surge and typhoon secondary disasters Urban flood monitoring and risk prevention Ocean geological disaster chain Engineering system simulation and maintenance Salt tide and associated hazards Land and seawater interactive pollution prevention and control Urban air pollution prevention and control 南海 - 陸架 - 河口多尺度動力過程 水沙通量與海岸地貌變化 水體污染容量與蓄滯機理 污染物多相轉化遷移 風暴湖及颱風次生災害 城市洪澇監測與風險防範 海洋地質災害鏈 工程系統模擬與維養 鹹潮及其次生危害 陸海統籌水污染防治 城區空氣污染防控 海洋生物資源與生態 Ocean biological resources and ecology
