“…Generally, a greater weight value indicates that an attribute or a subattribute is more intimately correlated with the stability of a slope. The determined weight vector for the three attributes (0.6, 0.2, 0.2) shows that the rock mass characteristics play the most important role in the stability of slopes, which agrees with the common understanding that the physical, mechanical, and geological properties of rock masses govern the stability of rock slopes [4,8,14,17,25,46,47]. Meanwhile, among the three subattributes of the rock mass characteristics, rock structure has greater importance over other two indexes, which is in line with the actual situation that most studied instable slopes are formed by bedding structures with multiple joint sets [59].…”

The stability of natural rock slopes is influenced by a wide spectrum of factors, such as mechanical properties of bedrocks and spatial distribution of discontinuities. Their specific values are typically incomplete, due mainly to the lack of effective and comprehensive methods to accurately characterize these factors, especially those inside of the slopes. The neutrosophic number is a useful tool to solve problems in indeterminate environment. This study introduces the neutrosophic theory into slope stability assessment. A vector similarity measure developed under neutrosophic environment was employed to establish a stability assessment method considering multilevel attributes of slopes. Using this method, the level of stability for studied slopes, i.e., stable, mostly stable, less stable, and instable, was determined by computing the relation indices. The method was applied to a group of rock slopes located in Zhejiang province, China, and the calculated results were compared with the reality of in situ survey. The field application showed that the developed method has a good efficiency and precision in assessing the stability of rock slopes. The obtained weight vector can reveal the key influential parameters that inherently control the stability of rock slopes.

“…Limit equilibrium and numerical analysis are the most common forms of deterministic method. The limit equilibrium method utilizes the static equilibrium principle to analyze the stress state under various failure modes of slopes [4], including Bishop's, Janbu's, Morgenstern-Price's and Fellenius' techniques, etc. [5][6][7].…”

“…6b). Some authors have argued that in the mining framework, human beings are an active factor contributing to disasters (Ramani, 1995); and with the scale of mining extending, landslide disasters on the Earth's surface will become increasingly serious (He et al, 2009).…”

Human topographic signatures and derived geomorphic processes across landscapes

The Earth's surface morphology, in an abiotic context, is a consequence of major forcings such as tectonic uplift, erosion, sediment transport, and climate. Recently, however, it has become essential for the geomorphological community to also take into account biota as a geomorphological agent that has a role in shaping the landscape, even if at a different scale and magnitude from that of geology. Although the modem literature is flourishing on the impacts of vegetation on geomorphic processes, the study of anthropogenic pressures on geomorphology is still in its early stages. Topography emerges as a result of natural driving forces, but some human activities (such as mining, agricultural practices and the construction of road networks) directly or indirectly move large quantities of soil, which leave dear topographic signatures embedded on the Earth's morphology. These signatures can cause drastic changes to the geomorphological organization of the landscape, with direct consequences on Earth surface processes. This review provides an overview of the recent literature on the role of humans as a geological agent in shaping the morphology of the landscape. We explore different contexts that are significantly characterized by anthropogenic topographic signatures: landscapes affected by mining activities, road networks and agricultural practices. We underline the main characteristics of those landscapes and the implications of human impacts on Earth surface processes. The final section considers future challenges wherein we explore recent novelties and trials in the concept of anthropogenic geomorphology. Herein, we focus on the role of high-resolution topographic and remote-sensing technologies. The reconstruction or identification of artificial or anthropogenic topographies provides a mechanism for quantifying anthropogenic changes to landscape systems. This study may allow an improved understanding and targeted mitigation of the processes driving geomorphic changes during anthropogenic development and help guide future research directions for development-based watershed studies. Human society is deeply affecting the environment with consequences on the landscape. Therefore, establishing improved management measures that consider the Earth's rapidly changing systems is fundamental. (C) 2015 Elsevier B.V. All rights reserved

Esse trabalho visa analisar a evolução antropogênica do relevo em algumas áreas de mineração no distrito de Itaoca, município de Cachoeiro de Itapemirim (ES). Para a obtenção das variáveis geomorfológicas declividade, curvatura horizontal (Convergente, Planar e Divergente), curvatura vertical (Côncavo, Retilínea e Convexa) e formas de terreno, foram utilizadas curvas de nível com equidistância de 10 em 10 metros de três áreas escolhidas no distrito. Para a elaboração do mapeamento do uso e cobertura da terra do distrito na escala de 1:5.000, foram utilizadas fotografias aéreas obtidas junto ao Instituto de Defesa Agropecuária e Florestal (IDAF) no primeiro período, denominado de 1970 e, da Hiparc Geotecnologias Ltda., no segundo período, denominado ano de 2012 ; sua classificação foi realizada a partir da tabela de classificação utilizada pela HIPARC Geotecnologia Ltda, a serviço do Instituto Estadual de Meio Ambiente (IEMA) no ano de 2012. Todo o processamento e geração de mapas foi realizado no ArcGisTM 10.2. Os resultados evidenciam o predomínio do uso e cobertura da terra de Pastagem nos dois períodos, a duplicação da área de mineração de 2,07% em 1970, para 4, 65% em 2012, a ampliação da massa de água associada a exploração em lavra de 2,40% em 1970 para 2.63% no ano de 2012. As variáveis geomorfológicas das três áreas escolhidas sofreram profundas alterações de um período para o outro devido a exploração mineral, gerando em alguns casos “Lagoa antropogênica ou antrópica de mineração” e “escarpa de mineração”, bem como, modificações na dinâmica hidrológica superficial e subsuperficial.
