Abstract An important first step in the geotechnical asset management of Great Smoky Mountains National Park (GRSM) is the creation of an unstable slope inventory along major transportation corridors. Slope-stability problems are frequent in GRSM, often initiated in highly weathered and fractured metasedimentary rocks. In this study, an unstable slope inventory was created using the Unstable Slope Management Program for Federal Land Management Agencies protocols. Hazards and risks were evaluated for 285 unstable slopes along 243.67 km of roadway. Kernel density estimation was used to identify unstable slope hotspots and establish 14 sites for site-specific investigations to evaluate potential impacts of discrete unstable slopes along major roadways. Two-dimensional probabilistic rockfall simulations and acid-base accounting tests were used to predict rockfall pathways and evaluate the acid-producing potential of rocks. Simulations indicated that rock material would likely enter the roadway at all 14 sites. Acid-base accounting test results indicated that slaty rocks of the Anakeesta Formation and graphitic schist of the Wehutty Formation are primary acid-producing rocks in rockfall-prone areas. This research illustrates an approach for prioritizing areas for site-specific investigations towards the goal of improving safety in GRSM, including developing mitigation strategies for rockfall by widening ditches, installing barriers, and encapsulating acidic rockfall material.

The Republic of North Macedonia undertakes intensive activities aimed at replacing fuels - fossil fuels with renewable energy sources and natural gas, to monitor the modern trends of exit from the energy crisis and environmental protection. Under the efforts of the National Gasification System in the country, i.e. the development of the existing gas infrastructure, the project for construction of the gas pipeline section Sveti Nikole – Veles was developed. The route of the gas pipeline starts east of the city of Sveti Nikole and ends south of the city of Veles with characteristics: DN 200, Ø 8” and length of 27.67 km. The Environmental Impact Assessment process is intended to serve as a primary input for the decision-making process by Macedonian authorities and the IFI in charge (EBRD in this case), which have to approve the Project before its implementation. The decision-making process includes the preparation of all documentation in accordance with the EBRD’s Performance Requirement (PR), The National Legislation, and Good International Practice (GIP). This EIA study identifies the potential negative impacts on the media in the environment from the relevant stages of the project i.e. pre-construction, construction, operations, and decommissioning and reinstatement, and proposes measures for their reduction or mitigation, i.e. improvement of the environment in the Environmental and Social Management Plan.

Even though the European roads are among the safest in the world, the number of road accidents is still a cause for concern. To reduce their number and consequences, many studies are being conducted, including knowledge of the factors that influence the occurrence of accidents. Forensic traffic experts are also part of the treatment of traffic accidents, and they often must base their conclusions on proven incomplete studies of data collected by police officers. In some cases, traffic accident data are still collected in classical ways and with classical measuring equipment. This is often a source of error. This paper defines these errors and offers solutions that are shown primarily through data capture using 3D scanners and photogrammetry. In this way, we can perfectly recreate the situation in the event of a traffic accident through 3D models, thus eliminating many shortcomings of police drawings and records. The article also proposes a central database of traffic accidents as an additional solution to gain a deeper insight into the causes and consequences of traffic accidents.

Residential wood combustion is the dominant source of particulate matter PM2.5 in the Republic of Croatia. Although the wood biomass is considered a green, sustainable energy source, at the same time the inhalation of PM2.5 particles from residential wood combustion, is associated with harmful effects on human health. The paper analyzes the variability of PM2.5 emission regarding three factors, which are closely related to climate policy and climate change. The first factor is related to the introduction of new, more environmentally friendly wood biomass combustion technologies. The second factor relates to the consumption of wood biomass depending on climate variability. The third factor refers to the implementation of measures for energy renovation of family houses. The aim of this paper is to distinguish the contribution of individual factors, both on the historical PM2.5 emissions from residential wood combustion, and on the emission projections up to the year 2050.

The paper presents the design of deep excavation support system in an urban environment. Excavation is carried out in the vicinity of surrounding buildings whose structural stability must be ensured during the execution of the construction works. The 60 cm thick diaphragm wall supported by the two rows (17.00 m and 18.25) of geotechnical anchors was selected as an excavation support system. The approximate floor plan dimensions of the diaphragm wall are 81x118 m, and the maximum excavation depth is 10.5 m. An additional challenge in designing the diaphragm wall is the presence of groundwater, whose maximum level is observed at a depth of approximately 5.8 m. In order to ensure the execution of construction works in dry conditions, a system of drainage trenches and wells is designed at the bottom of the pit. The diaphragm wall is designed in accordance with Eurocode 7.

Despite being potential historical sites, old embankment dams are subjected to many stability challenges due to many factors, including a lack of sufficient stability assessment tools by the time the dam was built and changes in embankment material properties induced by natural and human activities. Therefore, with the current advancement in technology is of great importance to investigate the state of old embankment dams under different potential loading conditions. The stability challenges become of more significant concern when the embankment is subjected to a rapid drawdown loading scenario. In this study, the Samarkand dam located in Karaganda province in Kazakhstan which was put into operation in 1941 is investigated in terms of seepage and slope stability with the help of numerical modelling. Both steady and transient (rapid drawdown) flow conditions are taken into consideration. e finite element method-based modelling is achieved using SEEP/W and SLOPE/W of the GeoStudio software. From the analysis results, it was observed that the old dam can be subjected to a potential failure under rapid drawdown conditions as the minimum factor of safety values were decreasing with the increase in the drawdown rates. For instance, the minimum factor of safety from the instantaneous drawdown rate was equivalent to 32.85% less than the factor of safety retrieved from the long-term steady-state conditions. Also, from Analysis of Variance (ANOVA), a p-value of 9.97× 10-29 was obtained after subjecting the factor of safety values from instantaneous, 5 days, 10 days, and 1 m per day drawdown rates to ANOVA, indicating that the factor of safety differences among the analyzed drawdown rates were statistically significant.
尽管是潜在的历史遗迹，但由于许多因素，包括大坝建成时缺乏足够的稳定性评估工具以及自然和人类活动引起的堤防材料特性的变化，旧堤防大坝受到许多稳定性挑战。因此，随着技术的进步，研究不同潜在荷载条件下老旧堤防坝体的状态具有重要意义。当路堤承受快速下拉荷载时，稳定性挑战变得更加重要。本文以1941年投入运行的哈萨克斯坦卡拉干达省撒马尔罕大坝为研究对象，采用数值模拟的方法对坝体渗流和边坡稳定性进行了研究。考虑了稳态和瞬态(快速下降)流动条件。利用GeoStudio软件的SEEP/W和SLOPE/W实现基于有限元法的建模。分析结果表明，随着落水速率的增大，最小安全系数逐渐减小，旧坝在快速落水条件下可能发生潜在破坏。例如，从瞬时降速获得的最小安全系数相当于从长期稳态条件获得的安全系数低32.85%。从方差分析(ANOVA)中，将瞬时、5天、10天、1 m / d的缩水率的安全系数进行方差分析，得到的p值为9.97× 10-29，表明所分析的缩水率之间的安全系数差异具有统计学意义。

Through the Natura 2000 policy, EU member states are committed to maintaining or restoring the favourable conservation status of a list of habitats and species throughout their territory. We show here that evaluating the effectiveness of this policy regarding its assigned objectives requires translating these objectives into normative reference and then describing the constraints on habitats and species that the policy seeks to conserve. We propose a strategic evaluation framework based on this principle, applied at the level of the Metropolitan French territory, by relying on the exploitation of several data sets, whose are generally not mobilised by the standard evaluation procedure. The results are broken down by natural ecosystems and biogeographical regions, providing a dashboard for the policy that is the basis for a comprehensive strategic evaluation.

Climate change implies a statistically significant change in the long-term mean state or characteristics of the variability of climate elements. It can be caused by natural and/or anthropogenic factors. Recent global warming is often cited as an example of human-induced climate change. Global warming refers to the increasing trend of the average global surface temperature of the Earth, defined as the global average of the mean annual surface temperature of the ocean, usually to a depth of 30-100 cm, and the mean annual surface temperature of the air above the land at a height of 1-2 m above the ground. In 1988, the World Meteorological Organization (WMO) and the United Nations Environment Program (UNEP) established the International Panel on Climate Change (IPCC), which assesses the state of the climate and the risk of climate change caused by human activities.To project climate change, it is necessary to determine the future emissions of greenhouse gases in the atmosphere. According to the IPCC, with appropriate scenarios of greenhouse gas emissions, an increase in the average global surface temperature of 1.5 °C to 4 °C is predicted by the end of the 21st century. The purpose of this paper is to show the relationship between the trend and variability of the global average of the mean annual surface temperature on Earth and the trend of the mean annual air surface temperature in Varaždin for the period 1949-2021. The results show significant correlations among them because Varaždin is located in an big area of surface air temperature anomalies which has a significant contribution to a global average anomalies in several last decades.

It is important to perform research to the degree that it is adequate to identify the features of the terrain composition, before, during, and after the building of facilities since predicting the behaviour of rock mass during tunnel construction is a complicated engineering challenge. Engineering research works in laboratories and in the field are of different scope and methodology during testing. In this paper, the established interdependencies of some of the basic parameters obtained during the testing of rock mass are presented: Edyn = f(Vp), Edyn = f(RMR) i Edyn = f(Q). Also, the relations between the engineering systems of rock mass classification and seismic primary waves are derived. RMR = f(Vp), Q = f(Vp). The relations were based on the examination of the rock mass for the construction needs of the tunnel on the Nis-Merdare highway. The results obtained in this study can be applied in environments that have similar lithological and structural characteristics.
