Summary: In Japan, most embankments lack seismic design, except for important ones like earth dams. However, recent seismic inspections have been conducted on existing embankments due to frequent damage caused by earthquakes, along with the implementation of countermeasures to stabilize them. This paper describes the current seismic inspection methods and countermeasures for river dikes, tailings dams, and embanked residential lands in Japan.

Summary: Green stormwater infrastructure (GSI) is an effective tool for meeting federal water regulations and mitigating urban flooding, but it also has social, ecological, physical, and economic impacts on local communities. This study conducted in Philadelphia identifies vulnerable communities and suggests equitable placements of GSI based on vulnerability indices and maintenance needs. The results reveal unequal distribution of vulnerabilities and emphasize the importance of optimizing GSI types for specific impacts.

Summary: This paper introduces a hierarchical RL formulation for maintenance planning on bridges, which addresses the challenges of complexity and scale. By utilizing state and temporal abstraction, the formulation decomposes large state and action spaces into smaller ones. Additionally, an open-source RL environment is developed to describe the propagation of deterioration condition over time, and demonstrated by solving maintenance planning problems at different levels.

Summary: Inspection planning, which involves planning motions for a robot to inspect points of interest, has wide applications in industrial, field, and medical robotics. It is computationally challenging due to the exponential growth of the search space with the number of points to inspect. We propose a novel method called IRIS that incrementally densifies a motion-planning roadmap and performs efficient near-optimal graph search. Our algorithm is proven to be asymptotically optimal and demonstrated to be significantly faster in generating higher-quality inspection plans compared to previous methods in various tasks.

Summary: Research has found that the flooding of infrastructure embankments can cause long-lasting destabilization due to internal erosion caused by seepage. The most common locations for material alteration in slopes were found to be along the base of slopes and in regions adjacent to water inflow. These findings have important implications for the stability of earthworks during and after flood events, as well as for the design of inspection and maintenance procedures.

Summary: There has been a significant increase in interest in adopting cutting-edge technologies such as monitoring IoT data and control automation systems in the civil engineering industry in recent years. Digital technologies like Digital Twin and laser scanners have become viable replacements for traditional methods, leading to changes in inspection, evaluation, and management of infrastructure, especially in bridge maintenance. The article proposes a conceptual framework for building management using Digital Twins and examines the obstacles in information standardization for the construction sector to benefit from Digital Twin technology.

Summary: Urban water utilities are increasingly adopting energy management strategies to reduce their carbon emissions and achieve zero carbon goals. A case study of the London water system suggests that a balanced approach, including self-generation of energy and purchasing green energy, can best navigate the trade-off between costs and sustainability in water supply systems.

Summary: The decarbonisation of heating and road transport are necessary but challenging steps towards achieving net zero carbon emissions. An integrated modeling approach combining national gas and electricity transmission networks with local energy systems and road transport models shows significant potential for efficiency improvements and cost savings, particularly through managed electric vehicle charging and provision of fast public charging facilities. Decarbonisation efforts require coordination between national and local governments and an integrated systems approach to energy and transport policies.

Summary: This study presents a new global modeling framework to explore the connections between ports, maritime transport, and global supply-chains. Through predicting trade flow allocation and evaluating the importance of ports for the economy, it quantifies the criticality of the world's 1300 most important ports for global supply chains. The results indicate that low-income countries and small islands are more reliant on their ports compared to the global average.

Summary: Nature-based solutions, such as sponge cities, have been advocated as a sustainable approach to urban stormwater management. However, there are limitations to their ability to absorb rainfall, making them insufficient in solving flooding problems in cities. This article argues that community-based measures are essential to transforming sponge cities into flood resilient cities. The prevalence of gated communities in Chinese cities provides a solid foundation for implementing these measures. The article discusses various community-based approaches, including resilience mapping, property-based measures, flood insurance, and social resilience building. It emphasizes the need for social transformation towards flood resilient communities.

Summary: Climate-induced extreme events could disrupt the operation of ports globally, affecting maritime transport, trade, and supply chains. The estimated impact on trade and economic activities across different sectors indicates a large global economic cost at-risk. The disruptions to ports from climate extremes have systemic impacts on global shipping, trade, and supply chains. By combining estimations of climatic-related port downtime with a global model of transport flows, the authors identify systemic risks to global maritime transport, trade, and supply-chain networks. On average annually, a total of US$81 billion of global trade and at least US$122 billion of economic activity are at-risk.
