A pioneering research project that aims to strengthen the resilience of sea walls to increased coastal flooding has been launched by Heriot-Watt University in Edinburgh, Scotland and Virginia Tech in Blacksburg, Virginia, USA. Around 148 million people worldwide are exposed to coastal flooding events, which are predicted to surge in frequency and severity in the coming decades as climate change drives sea levels higher. The research being conducted by Heriot-Watt and Virginia Tech will investigate how the soil behind sea walls is impacted by repeated wetting and drying cycles over time from waves overtopping the sea walls. It’s hoped this will highlight areas where the design and resilience of sea walls could be strengthened. Dr Melis Sutman, an Assistant Professor in Geotechnical Engineering at Heriot-Watt's School of Energy, Geoscience, Infrastructure and Society, said: “The sea level around the UK has already risen by around 1.5 millimetres a year on average from the start of the 20th century. And even in the best case climate change scenario, the sea level will continue to rise. So our coastal defence structures will be of paramount importance to defend our shorelines – not only for the UK, but also for the United States on the other side of the Atlantic.” More here: https://lnkd.in/ep_35gc4 #SustainableHWU #coastalflooding #ClimateAction Sherif Abdelaziz

Rising sea levels are causing coastal groundwater to lift closer to the ground. As they ascend, it becomes saltier and more corrosive, posing a risk to buried and partially buried infrastructure. When buried and semi-buried infrastructure, such as sewer lines, roadways, and building foundations, comes into contact with these salty waters, it can corrode and fail. #ClimateAdaptation #ClimateRisk #infrastructureresilience https://lnkd.in/dbaY3KSU

Navigating Sea Level Rise: Adapting Infrastructure to Climate Change Challenges Rising sea levels present unprecedented challenges for infrastructure worldwide. As many as 410 million people could be vulnerable to rising sea levels by the end of the century according to World Economic Forum (Dec 2022). Here's how we can tackle them: 🌊Coastal Defense Systems: Implementing robust coastal defense mechanisms, such as sea walls, surge barriers, water pumps and overflow chambers to keep water out are among the coastal defences being used, to protect critical infrastructure from inundation and erosion. 🌊Elevation and Resilient Design: Designing infrastructure with elevation in mind and incorporating resilient features to withstand the impacts of sea level rise and extreme weather events. 🌊Infrastructure Redesign: Retrofitting existing infrastructure and incorporating climate resilience into new construction projects to enhance durability and longevity. 🌊Natural Solutions: Embracing nature-based solutions like wetland restoration and mangrove conservation to provide natural buffers against rising sea levels and storm surges. 🌊Integrated Planning: Adopting comprehensive planning approaches that consider the interconnectedness of infrastructure systems and their vulnerability to climate change impacts. 🌊Investment in Innovation: Investing in research and development of innovative technologies and solutions for climate-resilient infrastructure, such as floating infrastructure and adaptive building materials. Together, by prioritizing adaptation strategies and collaboration across sectors, we can build a more resilient future in the face of climate change-induced sea level rise. #ClimateChange #Infrastructure #Resilience #bnz #cleanenergy #verdianpower 🌍💡 Photo’s reference : Mataro (Barcelona,Spain) ‘s Sant Simo beach vanishes recently after storm Nelson (1/1/2024)

Assessment of relative land surface deformation over time using InSAR can enable improvements in planning for resilient critical infrastructure design. Climate change, geologic hazards, and over-drafting of ground water aquifers all contribute to the instability of urban landscapes. InSAR monitoring analysis at regional scale can help!

🌍 𝐔𝐧𝐝𝐞𝐫𝐬𝐭𝐚𝐧𝐝𝐢𝐧𝐠 𝐭𝐡𝐞 𝐂𝐚𝐮𝐬𝐞𝐬 𝐨𝐟 𝐋𝐚𝐧𝐝 𝐒𝐮𝐛𝐬𝐢𝐝𝐞𝐧𝐜𝐞 𝐢𝐧 𝐑𝐚𝐩𝐢𝐝𝐥𝐲 𝐃𝐞𝐯𝐞𝐥𝐨𝐩𝐢𝐧𝐠 𝐂𝐨𝐚𝐬𝐭𝐚𝐥 𝐂𝐢𝐭𝐢𝐞𝐬 🌊🏙️ In rapidly developing coastal cities, it is vital to explore the underlying causes of land subsidence. The primary factors that contribute to this pressing issue are as follows. 𝙂𝙧𝙤𝙪𝙣𝙙𝙬𝙖𝙩𝙚𝙧 𝙀𝙭𝙩𝙧𝙖𝙘𝙩𝙞𝙤𝙣: Urban populations lead to an increased demand for groundwater, which can result in aquifer compaction and land subsidence when extracted excessively. 𝐔𝐫𝐛𝐚𝐧𝐢𝐳𝐚𝐭𝐢𝐨𝐧 𝐚𝐧𝐝 𝐈𝐧𝐟𝐫𝐚𝐬𝐭𝐫𝐮𝐜𝐭𝐮𝐫𝐞: The construction of buildings, roads, and other infrastructure adds weight to the land surface, causing it to sink. Poor land-use planning exacerbates this impact. 𝙉𝙖𝙩𝙪𝙧𝙖𝙡 𝙋𝙧𝙤𝙘𝙚𝙨𝙨𝙚𝙨: Coastal cities are particularly vulnerable to natural processes like soil compaction, sediment consolidation, and erosion, which can accelerate land subsidence. 𝙎𝙚𝙖 𝙇𝙚𝙫𝙚𝙡 𝙍𝙞𝙨𝙚: Rising sea levels due to climate change increase hydrostatic pressure on coastal land, exacerbate subsidence, and pose significant threats to infrastructure and communities. 𝐒𝐞𝐝𝐢𝐦𝐞𝐧𝐭 𝐄𝐱𝐭𝐫𝐚𝐜𝐭𝐢𝐨𝐧: Sand and gravel extraction for construction purposes further destabilizes coastal areas, leading to land subsidence and increased susceptibility to erosion and flooding. Addressing these issues requires a multi-faceted approach involving sustainable urban planning, responsible groundwater management, coastal protection measures, and climate change mitigation efforts. As professionals committed to sustainable development, it is crucial that we raise awareness about the reasons for land subsidence and advocate for comprehensive solutions to safeguard the future of our coastal cities. Let us collaborate and drive meaningful changes in resilient and thriving coastal communities. Thus, we can make a difference: 🌊💡 If you are attending European Geosciences Union (EGU) 2024, let connect together.

Technically known as “subsurface heat islands,” #undergroundclimatechange is the warming of the ground under our feet, caused by heat released by buildings and subterranean transportation such as subway systems. Another piece in this puzzle…

To better predict and prepare for how extreme rainfall might intensify in the future, a UConn professor is leading a team of researchers investigating the relationship between the intensity of extreme precipitation and temperature. UConn professor of civil and environmental engineering Guiling Wang and her collaborators received a $900,000 U.S. Department of Energy grant to conduct climate research. Precipitation events of extreme intensity are causing more frequent flash floods worldwide. In the United States, especially in the Northeast, flash floods in recent years have claimed lives and destroyed property, roads, bridges, and other critical infrastructure. #uconnresearch #climatechange #climatechangeresearch #precipitationresearch #precipitation #flashflood #flooding #climatemodels https://lnkd.in/eckNhGWj
