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.","PeriodicalId":50518,"journal":{"name":"Environmental & Engineering Geoscience","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135627863","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.","PeriodicalId":50518,"journal":{"name":"Environmental & Engineering Geoscience","volume":null,"pages":null},"PeriodicalIF":0.9,"publicationDate":"2022-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85274851","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.","PeriodicalId":50518,"journal":{"name":"Environmental & Engineering Geoscience","volume":null,"pages":null},"PeriodicalIF":0.9,"publicationDate":"2022-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73511824","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.","PeriodicalId":50518,"journal":{"name":"Environmental & Engineering Geoscience","volume":null,"pages":null},"PeriodicalIF":0.9,"publicationDate":"2022-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82275648","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.","PeriodicalId":50518,"journal":{"name":"Environmental & Engineering Geoscience","volume":null,"pages":null},"PeriodicalIF":0.9,"publicationDate":"2022-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72455335","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
