Public descriptionVietnam is one of the most vulnerable countries to the impacts of climate change. The frequency and severity of typhoons are expected to increase consequently increasing the risks of wind damage, flooding and landslide. Low lying areas of Vietnam, the Mekong Rive Delta (MRD), are particularly vulnerable to sea level rise.In recent years rapid economic growth has been enabled by improvements to the transportation infrastructure including major bridges replacing less reliable ferries. These bridges allow efficient transportation of goods manufactured in MRD to HCMC and provide emergency access during natural disasters such as typhoons and flood events when ferries are unable to operate safely.In southern Vietnam, particularly in MRD, land subsidence due to excessive ground water extraction is exacerbating the risks of sea level rise due to climate change. This has an impact on daily life and key infrastructure assets, including major bridges.UbiPOS and the University of Nottingham (UNOTT) have collaborated to develop GeoSHM, an SHM solution that exploits satellite data for bridge monitoring and remote sensing of ground motion. GeoSHM will be deployed in Vietnam to develop sustainable communities and cities (SDG 11) and mitigate the risks of climate change (SDG 13) by (i) monitoring the impact of climate change on bridge performance and long-term ground level, (ii) empowering the maintenance of key bridge assets through smart data processing and (iii) ensuring the ongoing safe operation of these assets to underpin future growth and maintain emergency access. GeoSHM will enable the implementation of plans to efficiently maintain the bridges and ensure fully functioning road networks during and after extreme events (T11.5; T13.1). The data provided by GeoSHM will support the development of national policies and strategies to mitigate the risks of climate changes (T11.b; T13.2) and enable more effective climate-change-related planning (T13.3).This feasibility project will enable UbiPOS and UNOTT to extend their work to the Vietnamese context. An SHM workshop in HCMC will demonstrate the capabilities of SHM to local engineers and researchers, and establish the key user needs of infrastructure operators in Vietnam. The Vietnamese partner will visit the UK to meet the SHM research group at Nottingham and see the implementation of the GeoSHM system on the Forth Road Bridge (Edinburgh, UK). Having established the feasibility of deploying GeoSHM in Vietnam and developed working relationships with researchers, engineers and government officials, UbiPOS will be well prepared to move on to a demonstration project.

公共宣传越南是最容易受到气候变化影响的国家之一。预计台风的频率和严重程度将增加，从而增加风灾、洪水和山体滑坡的风险。湄公河三角洲（MRD）是越南的低洼地区，特别容易受到海平面上升的影响。近年来，通过改善交通基础设施，包括大型桥梁取代不太可靠的渡轮，经济快速增长。这些桥梁可以有效地将MRD制造的货物运输到胡志明市，并在台风和洪水等自然灾害时提供紧急通道，当渡轮无法安全运行时。在越南南部，特别是MRD，由于过度抽取地下水而导致的地面沉降加剧了气候变化导致海平面上升的风险。UbiPOS和诺丁汉大学（UNOTT）合作开发了GeoSHM，这是一种利用卫星数据进行桥梁监测和地面运动遥感的SHM解决方案。GeoSHM将在越南部署，以发展可持续发展的社区和城市（SDG 11），并通过以下方式减轻气候变化的风险（SDG 13）：（i）监测气候变化对桥梁性能和长期地面的影响，（ii）通过智能数据处理增强关键桥梁资产的维护能力，以及（iii）确保这些资产的持续安全运行，以支持未来的增长并保持紧急访问。GeoSHM将使计划的实施，以有效地维护桥梁，并确保道路网络在极端事件期间和之后的充分运作（T11.5; T13.1）。GeoSHM提供的数据将支持制定国家政策和战略，以减轻气候变化风险（T11.b; T13.2），并实现更有效的气候变化相关规划（T13.3）。该可行性项目将使UbiPOS和UNOTT能够将其工作扩展到越南的背景。胡志明市的SHM研讨会将向当地工程师和研究人员展示SHM的能力，并确定越南基础设施运营商的关键用户需求。越南合作伙伴将访问英国，在诺丁汉会见SHM研究小组，并在福斯公路桥（爱丁堡，英国）上看到GeoSHM系统的实施。在确定了在越南部署GeoSHM的可行性，并与研究人员、工程师和政府官员建立了工作关系后，UbiPOS将为进入示范项目做好充分准备。
