“…Mckim, 1992, defined risk as "an uncertainty associated with any outcome". This implies that the risk-based approaches focus on the negative impacts and their prevention (Hokstad & Steiro, 2006). As such, the www.ccsenet.org/jsd Journal of Sustainable Development Vol.…”

Every Environmental Management System [EMS] requires implementing organizations to identify the environmental aspects of their activities, products or services and clearly show how the identification of aspects that may have significant impacts on the environment are identified. However, procedures for the identification of aspects that are significant are not clearly defined. This paper adapt and modify the process used to identify project risks as a framework to develop a generic framework that can be used by all manufacturing and service organizations to identify the environmental aspects of their activities as well as those that are significant. The proposed framework outlines four key steps in identifying impacts that are significant, viz. Environmental Aspects Identification; Environmental Risk Assessment; Environmental Risk Profiling; and Environmental Risk Threshold Values.The paper assesses the usability of the proposed framework by choosing one of the key activities in the mining sector as a test case. In this text case, the model identified dust as the most significant environmental impact in a typical hauling operation in a mine.

“…In this sense, RMas -also known as Risk Analysis architectures (RAas) -focus on this target, trying to identify, classify, and evaluate the hazards in order to delimit their effects and coverage. [28,29] Besides, since RMas are generic evaluative frameworks, they have been employed in multitude of fields and areas. Economists, engineers, consultants, or merchants have adapted similar structures to their workspace and requirements.…”

Safe operation of mini UAVs: a review of regulation and best practices

This paper is focused on the safety of mini UAV (mUAV) systems. It presents the great efforts that are being done in air legislation, including the present and future normative. Nevertheless, considering that the work is not finished yet, a low-level risk analysis concept is introduced. Based on the international regulations, a specific three-step structure for mUAV hazard analysis is presented: identification, assessment, and reduction in a recursive loop that provides a solid architecture for facing the wide range of possible risks.

“…At present, risk analysis of water conservancy is focused on the hydrological risk and hydraulic risk, but there is hardly risk analysis for the structural aspects. The only relevant literatures [9][10][11] are mainly on the issues of overtopping and instability failure of embankment dam, since the structure and failure mechanism are relatively simple. Risk analysis for concrete dam especially the high arch dam is just in the infancy stage, and its main research results are as follows.…”

To develop national economy and use the water resources and hydropower resources sufficiently, a lot of high arch dams, with the height of more than 200 m, have been and will be built in China. Although arch dams have good mechanical behavior, there is still failure possibility due to the huge water pressure and high stress level in dam, complex topographic and geologic conditions, formidable environment and high intensity earthquake. As one of the three main aspects concerning the safety of high arch dam, the study on global destruction, has been elaborated in the literatures, and research advance in the other two aspects, namely the failure risk and local damage of high arch dams, will be reviewed in this paper. In recent years, the failure risk of high arch dams has been investigated, and the model for identifying dam failure risk factors has been established. It is shown that the foundation deterioration and strong earthquake are the major risk sources for high dam failure. With the fault tree method, the failure mode and failure probability of high arch dams are studied, and the principle for determining failure mode and the method of calculating failure probability are proposed. Meanwhile, the determination principle of acceptable risk standard for high arch dam was proposed, and the acceptable risk rate and the acceptable standard value of various risk losses were given. For the local damage of arch dam, it is pointed out that the local damage belongs to the strength failure at material level. The study on local failure mechanism of arch dam is reviewed, based on the theories that from traditional strength theory to damage mechanics and meso-mechanics theory. Aiming at the cracking, the main pattern of local failure of high concrete dam, the research advances in the analysis methods and cracking criteria for smeared crack model and discrete crack model are summarized, and the research findings of preventive measures for local failure are shown. high arch dam, failure risk, local damage, research advance Citation:Ren Q W, Li Q, Liu S. Research advance in failure risk and local strength failure for high arch dams. Chin Sci Bull, 2012Bull, , 57: 46724682, doi: 10.1007 To develop national economy, to save energy and to reduce emission, exploitation and utilization of water resources and hydropower resources are continued in China. At present, the height of arch dams under construction and to be built are of 300 m high level, such as Jinping arch dam (305 m high), Xiaowan arch dam (294.5 m high), Xiluodu arch dam (285.5 m high), and Baihetan arch dam (289 m high). The construction scale and difficulty of these dams are beyond the current design specifications, and there is hardly successful precedential reference. Moreover most of these high arch dams are located in the western region of China, where the topographic and geologic conditions are quite complex, with harsh environment and high seismic intensity as well as frequent geological disasters. In addition the resistance of dam and foundation may be red...
