Solid waste landfills serve as municipal waste containment facilities. Presently, landfills are required to accommodate as much volume of waste as possible while isolating the waste from surrounding air, soil and ground water. With the intention to provide sufficient space for the increasing waste volumes, modified landfill designs have been implemented which incorporate designs with steep side slopes. Although the National Norms and Standards for Disposal of Waste to Landfill provide the minimum requirements and state that alternative design layouts for landfill slopes exceeding 1H:4V may be considered, the new implementation could increase the risk of landfill instability (Department of Environmental Affairs, 2013a; Emery, 2014). Research has shown that instability problems may be associated with shear failure (Russell, et al., 1998; Kim, 2006; Feng, et al., 2010; Duffy, 2016). In such cases, the safety of these containment facilities depends on the shear strength properties of the landfill boundary conditions and construction materials. As a result, proper understanding of shear strength parameters is essential in ensuring safe designs.
This book presents select proceedings of the Third International Conference on Environmental Geotechnology, Recycled Waste Materials and Sustainable Engineering (EGRWSE-2022). It covers state-of-the-art research on environmental geotechnology, sustainability, and use of recycled waste materials for civil infrastructure along with latest accomplishments, trends, concerns, innovations, practical challenges encountered, and the solutions adopted in this field. Given the contents, this book is useful for researchers, engineers, and professionals working in the areas of geoenvironmental engineering, waste management, and sustainable engineering and associated fields.
During the eleventh and twelfth centuries A.D., the Mogollon Rim region of east-central Arizona was a frontier, situated beyond and between larger regional organizations such as Chaco, Hohokam, and Mimbres. On this southwestern edge of the Puebloan world, past settlement poses a contradiction to those who study it. Population density was low and land abundant, yet the region was overbuilt with great kivas, a form of community-level architecture. Using a frontier model to evaluate household, community, and regional data, Sarah Herr demonstrates that the archaeological patterns of the Mogollon Rim region were created by the flexible and creative behaviors of small-scale agriculturalists. These people lived in a land-rich and labor-poor environment in which expediency, mobility, and fluid social organization were the rule and rigid structures and normative behaviors the exception. Herr's research shows that the eleventh- and twelfth-century inhabitants of the Mogollon Rim region were recent migrants, probably from the southern portion of the Chacoan region. These early settlers built houses and ceremonial structures and made ceramic vessels that resembled those of their homeland, but their social and political organization was not the same as that of their ancestors. Mogollon Rim communities were shaped by the cultural backgrounds of migrants, by their liminal position on the political landscape, and by the unique processes associated with frontiers. As migrants moved from homeland to frontier, a reversal in the proportion of land to labor dramatically changed the social relations of production. Herr argues that when the context of production changes in this way, wealth-in-people becomes more valuable than material wealth, and social relationships and cultural symbols such as the great kiva must be reinterpreted accordingly. Beyond Chaco expands our knowledge of the prehistory of this region and contributes to our understanding of how ancestral communities were constituted in lower-population areas of the agrarian Southwest.
Acclaimed geologist Robert Thorson has been fascinated by kettle lakes ever since his youth in the upper Midwest. As with historic stone walls, each kettle lake has a story to tell, and each is emblematic of the interplay between geology and history. Beyond Walden covers the natural history of kettle lakes, a band of small lakes that extends from the prairie potholes of Montana to the cranberry bogs of Cape Cod. Kettle lakes were formed by glaciers and are recognizable by their round shape and deep waters. Kettles are the most common and widely distributed "species" of natural lake in the United States. They have no inlet or outlet streams so they are essentially natural wells tapping the groundwater. Isolated from one another, each lake has its own personality, and is vulnerable to pollution and climate warming. The most famous kettle lake is Walden Pond in Concord, Massachusetts; but northern Wisconsin, Michigan, and Minnesota are most closely associated with them. These lakes have had a tremendous impact on the livelihood and lifestyles of peoples of the area--Native Americans, early explorers and settlers, and the locals and tourists who now use the lakes for recreation. Thorson explores lake science: how kettle lakes are different from other lakes, what it takes to keep all lakes healthy, how global warming and other factors affect lakes. Beyond Walden has a strong environmental message, and will do for the kettle lakes of America's Heartland--and beyond--what Stone by Stone did for the historic stone walls of New England.
The construction materials industry is a major user of the world’s resources. While enormous progress has been made towards sustainability, the scope and opportunities for improvements are significant. To further the effort for sustainable development, a conference on Sustainable Construction Materials and Technologies was held at Coventry University, Coventry, U.K., from June 11th - 13th, 2007, to highlight case studies and research on new and innovative ways of achieving sustainability of construction materials and technologies. This book presents selected, important contributions made at the conference. Over 190 papers from over 45 countries were accepted for presentation at the conference, of which approximately 100 selected papers are published in this book. The rest of the papers are published in two supplementary books. Topics covered in this book include: sustainable alternatives to natural sand, stone, and Portland cement in concrete; sustainable use of recyclable resources such as fly ash, ground municipal waste slag, pozzolan, rice-husk ash, silica fume, gypsum plasterboard (drywall), and lime in construction; sustainable mortar, concrete, bricks, blocks, and backfill; the economics and environmental impact of sustainable materials and structures; use of construction and demolition wastes, and organic materials (straw bale, hemp, etc.) in construction; sustainable use of soil, timber, and wood products; and related sustainable construction and rehabilitation technologies.
"Advances in Environmental Geotechnics" presents the latest developments in this interdisciplinary field. The topics covered include basic and advanced theories for modeling of geoenvironmental phenomena, testing and monitoring for geoenvironmental engineering, municipal solid wastes and landfill engineering, sludge and dredged soils, geotechnical reuse of industrial wastes, contaminated land and remediation technology, applications of geosynthetics in geoenvironmental engineering, geoenvironmental risk assessment, management and sustainability, ecological techniques and case histories. This proceedings includes papers authored by core members of ISSMGE TC5 (International Society of Soil Mechanics and Geotechnical Engineering---Environmental Geotechnics) and geoenvironmental researchers from more than 20 countries and regions. It is a valuable reference for geoenvironmental and geotechnical engineers as well as civil engineers. Yunmin Chen, Xiaowu Tang, and Liangtong Zhan are Professors at the Department of Civil Engineering of Zhejiang University, China.
