Protecting coastlines and developing cities

Wei Xinchen || An innovative researcher in the field of coastal resilience.

Coastal resilience and soft urban planning are important initiatives to ensure sustainability and safety in areas vulnerable to the effects of climate change. Based on this theme, we aim to protect communities from natural disasters while promoting biodiversity and enhancing the quality of life in cities. Coastal resilience requires technical solutions such as seawalls, tidal energy utilization, and nature-friendly coastline conservation measures. On the other hand, soft urban planning focuses on improving the quality of residents' living spaces, such as the creation of parks and green belts, the development of waterside recreational areas, and planning with citizen input. These initiatives aim to transform cities into stronger and more attractive places while minimizing the impact on the environment. The integration of coastal resilience and soft urban planning is a challenge that we all need to work on together to provide a safe and sustainable environment for future generations.

I received my Bachelor of Engineering degree from Tsinghua University and further received my Master of Landscape and Regional Planning and Certificate in Urban Resilience from the University of Pennsylvania. I worked as a student researcher in three different research groups, each of which made a unique contribution to my expertise in coastal resilience. In particular, I participated in the Retreat by Design project, a collaboration with government agencies and flood management authorities in New York City, focusing on coastal resilience and managed retreat. This effort combined geospatial analysis from above with community workshops from below, where I also conducted simulations of coastal dynamics and identified previously unrecognized risk areas. My work at Tsinghua University was dedicated to assessing the impacts of climate change on coastal communities and habitats, with a particular focus on the proposed Marin National Park. Additionally, earlier this year, I joined a research team studying climate migration and land use change at a global scale. These roles sharpened my abilities in spatial analysis, oceanography, and design, and enhanced my ability to translate theoretical solutions into practice, especially in delta environments.

Risk assessment and feasibility study

Sea-level rise can accelerate coastal erosion, threatening infrastructure, homes, and ecosystems. Erosion reduces natural barriers that protect coastal towns from the sea, making them more vulnerable to typhoons and floods. Subsidence and saltwater intrusion amplify the effects of sea-level rise, which could have long-term effects on local communities. Amid this complex transformation and widespread retreat of coastal industries, the selection of sites and measures to be protected is key to making feasible decisions to incorporate limited local and state budgets in disadvantaged locations. Coastal protection plans will require a systematic framework to function. Isolated project sites cannot withstand the scale of disasters brought by typhoons, and mesoscale events tend to be too intense to develop any kind of mitigation plan.

Planning, Zoning and Infrastructure Systems

We find that while local infrastructure has limited function for the area, its impacts go beyond the local limit, and that a set of infrastructure placed at choke points may meet the local requirements for risk mitigation. Developing this type of strategy requires more modeling and data processing, but it can open up opportunities to make town resilience planning more cost-effective. Recognizing the complexity of the decision-making process, which involves many iterations and ramifications, is key to establishing a nuanced scale for the extent of protective measures to be built in coastal cities and rural areas, and this detailed scale, combined with thorough assessments, can help predict changes in urban form, including road networks, zoning, and waterfront activities, rather than relying on a single, inflexible proposal.
