For instance, as is shown in Figure 1, the proportion of urban dwellers has increased from 30% in 1950 to 55% in 2018 and is projected to rise to 68% by 2050. The rate of urbanisation is even more pronounced in less developed countries (United Nations, Department of Economic and Social Affairs, Population Division 2018a). Furthermore, the urban population is increasingly concentrating into so-called megacities, i.e., ‘urban agglomerations’ with 10 million or more residents; the proportion of urban residents residing in megacities has increased from 3% in 1950 to 12% in 2015 and is expected to grow to 16% in 2035 (United Nations, Department of Economic and Social Affairs, Population Division 2018b, 55, and 2018c). Because urban infrastructure is difficult to modify, as urban areas grow, new development must fit into the existing urban fabric. Moreover, as density increases, space will become more difficult to come by, requiring new ways of meeting the needs of urban dwellers. At a global scale, there is an increasing need to reduce resource use across all economic sectors, and disasters are increasing in frequency and their social and economic consequences. On top of this, the increased complexity and interdependency of infrastructure systems increases the chances of cascading infrastructure failures.","PeriodicalId":50689,"journal":{"name":"Civil Engineering and Environmental Systems","volume":null,"pages":null},"PeriodicalIF":1.8,"publicationDate":"2022-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86879654","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Electricity, water, buildings, transport networks, and communication systems are each delivered separately. Recent advancements in the development of energy micro-grids have opened the possibility of localised, intensive, and complex, nature-based infrastructure ecosystems. Designed at the scale of a village, such systems would integrate different types of infrastructure. For example, an energy micro-grid can provide electricity to buildings, power electric vehicles and cycle water through a precinct. In turn, the water system can store energy and irrigate a diverse, regenerative food system. Providing housing close to food production reduces transport costs, supply chain losses and packaging. The significant land area required for each village would result in a dispersal of populations, creating networks of villages, each with integrated infrastructure ecosystems. This challenges the orthodoxy in town planning and regional economics that accepts ever-increasing urbanisation. To synthesise ideas developed in different disciplines we adopt the epistemology of consilience. That is, a conclusion can be confirmed when different disciplines arrive at that same position. We show that literature in town planning, regional economics, ecological economics, and public health all support the argument for dispersal reached through civil engineering systems.","PeriodicalId":50689,"journal":{"name":"Civil Engineering and Environmental Systems","volume":null,"pages":null},"PeriodicalIF":1.8,"publicationDate":"2022-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89749033","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The transition from direct burial to utilidors in older, dense American cities has generally not occurred, despite the potential to increase system performance in a long-term, financially and environmentally sustainable manner, because it would require reform of local planning practices and of utility pricing to support financing within a complex regulatory system. Utilidor adoption in New York City (NYC) would be a significant local infrastructure transition, amplifying the need for locality-based research, that would occur while each utility sector undergoes its own infrastructure transitions, thereby increasing the level of regulatory complexity. This paper applies transitions analysis, recursive collective action theory, and capacity to act analysis to NYC’s experience with its PROW subsurface spaghetti problem and utilidor implementation to demonstrate a place-based methodology that identifies specific sources of resistance to innovative subsurface design and feasible pathways for resolving them. This methodology would be transferable for application to other American cities or classes of American cities to supplement the limits of generalised subsurface and subsurface resource integration research for practitioner application.","PeriodicalId":50689,"journal":{"name":"Civil Engineering and Environmental Systems","volume":null,"pages":null},"PeriodicalIF":1.8,"publicationDate":"2022-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82018033","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This breadth creates an interconnected complexity and the potential for perceived intractability. Tackling water security meaningfully therefore requires a judgement in balancing the holistic nature of water security with reductionist understanding of key processes and elements. This paper demonstrates that systems thinking can be adapted to achieve this through different systems framings of water security, tailored to local context. Through four case studies, we show how systems thinking has been adapted and applied to fit the contextual analysis and management of multiple water security issues. We show how this approach has dissolved disciplinary and sectoral silos; changed the spatial scale at which water security is addressed; improved data acquisition and analysis to better understand relationships between sub-systems; and integrated socio-ecological issues of justice and power with more traditional bio-physical understandings of water security. This is an important step towards turning systems thinking into systems transformation and making the concept of water security actionable and accessible to policy, planning, and practice.","PeriodicalId":50689,"journal":{"name":"Civil Engineering and Environmental Systems","volume":null,"pages":null},"PeriodicalIF":1.8,"publicationDate":"2022-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73135829","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The required data of the ANN meta-model was generated using 150 three-dimensional finite-difference simulations. The global sensitivity analysis was performed on 19 parameters, including 17 geotechnical parameters of soil layers and 2 operational parameters of face pressure and grouting pressure. The predicted results using ANN were in good agreement with the numerical simulations so that R = 99% and rRMSE = 1.5% are obtained. Then, back analysis was performed using the ANN-GA hybrid algorithm and the geotechnical data of the monitoring point were updated using the maximum surface settlement monitored at this point. Also, for the geotechnical parameters considered in the design phase, using the same algorithm, the number of operational parameters required for optimal settlement was predicted.","PeriodicalId":50689,"journal":{"name":"Civil Engineering and Environmental Systems","volume":null,"pages":null},"PeriodicalIF":1.8,"publicationDate":"2022-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73833424","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
