Only by understanding the local, national, and global contexts and processes of urban regeneration can inferences, lessons, and best practices be made. The objective of this study is to review the literature on urban regeneration and evaluate contemporary alterations and their implications for future city renewal. The rehabilitation of Ovidiu’s waterfront is a unique issue, considering the city’s location, its openness to Lake Siutghiol, which is separated from the Black Sea by only a 400m wide cordon, and the presence of the Roman camp and the aqueduct that previously supplied the Roman castle of Tomis. Lake Siutghiol has considerable growth potential due to the direct connection between Ovidiu and Mamaia, a popular tourist destination recently attracting many investors.","PeriodicalId":345086,"journal":{"name":"Ovidius University Annals of Constanta - Series Civil Engineering","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130762722","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Since the pollution level of the Nokoué Lake (Benin) became a concern, the present study was carried out to better understand and manage the quality of the surface water of this lake, to reduce the risks to damage the population health and the ecosystem equilibrium. The objective of the present work is the statistical study of the pollutants concentration data using Principal Component Analysis (PCA) and clustering. The concentration of five pollutants, namely NO3−, NH4+, NT (total nitrogen), PO43−, and total phosphates (PT) were sampled on thirty-three sites of the Nokoué Lake and analyzed. Three principal components have been selected and the sites have been grouped in three clusters, one of them containing only the sites on Cotonou.","PeriodicalId":345086,"journal":{"name":"Ovidius University Annals of Constanta - Series Civil Engineering","volume":"88 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132748226","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For the present study three structures with six storeys are subjected to a time history analysis. To study the effect of dampers in structures in comparison with structures stiffened by large sections and centrally braced, are analysed the relative level displacements, maximum displacement on the top, variation of lateral acceleration at the last level and variation of the maximum seismic base shear force depending on the lateral rigidity. The results indicate that placement of friction dampers improve the response of structures in all analyzed terms.","PeriodicalId":345086,"journal":{"name":"Ovidius University Annals of Constanta - Series Civil Engineering","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130085781","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Once completed, it will have the ability to cover around 10% of gas needs of Romanian population. Currently there is about 10 Bcm of resources to be produced at a rate of about 1 Bcm per annum. The infrastructure was thought to be used for the production of gas from the reservoirs of Ana and Doina, in the first place. But the long term vision of the project consists in converting the already existent infrastructure to develop green energy projects, such an offshore wind plant, solar panels fields or production of hydrogen, projects that may start time before decommissioning of the gas production platform.","PeriodicalId":345086,"journal":{"name":"Ovidius University Annals of Constanta - Series Civil Engineering","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129532389","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, the purpose of the present article is to identify the areas that present a high susceptibility to flash-floods in the Vărbilău catchment. The area, located in the Prahova region, was chosen due to the complexity of the hydrological phenomena. To determine the susceptibility to flash floods, the Flash Flood Susceptibility Index (FFSI) was calculated by integrating ten factors that play an essential role in the flash floods formation. Areas located downstream and in the middle of Vărbilău basin present a low risk, while locations in the northwest (upstream of Luţu Roşu and Scurteşti) present a high risk to flash-floods due to steep slope, narrow valleys, solid rocks, and land use.","PeriodicalId":345086,"journal":{"name":"Ovidius University Annals of Constanta - Series Civil Engineering","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130802144","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The comfort criteria depend of the frequencies and accelerations of the structure and have to be situated between certain limits. If the frequencies and accelerations of the structure are in the critical domains, measures to modify them have to be taken, some of them being presented in this paper as they are the most usually used.","PeriodicalId":345086,"journal":{"name":"Ovidius University Annals of Constanta - Series Civil Engineering","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121552515","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
