Öğe A Review on the Critical Factors Causing Delay of Delivery Time in Construction Projects(İstanbul Gelişim Üniversitesi Yayınları / Istanbul Gelisim University Press, 2020) Tafesse, ShitawCompleting the construction projects as per the scheduled time is an underlined issue for the success of the projects. However, several construction projects are confronted in completing within the agreed contractual project duration. In addressing influential factors contributing to delay of delivery time in construction projects, a remarkable number of studies have been conducted and published over the past decades. However, it seems that a summary and organizing of the research development in this discipline is not popularized. Therefore, this paper aims to review the existing research trend on the factors causing delays in construction projects. The review is very useful for industry practitioners and scholars to provide comprehensive and precious sources. Also, it provides a discussion, conclusion, and future research directions.Öğe Influence of Climate Change on the Flood Disasters in Bursa, Turkey(İstanbul Gelişim Üniversitesi Yayınları / Istanbul Gelisim University Press, 2020) Balov, Mustafa NuriThe recent increase in the frequency and intensity of the floods resulted from huge precipitation events in Bursa Province, Turkey, is the main motivation of this study. For this purpose, the daily precipitation values from the historical data recorded between 1971 and 2000 together with the projected data of the NorESM1-M general circulation model under RCP4.5 and RCP8.5 scenarios between 2031 and 2100 were used to calculate eight extreme precipitation events. The Spearman's rho and the Mann-Kendall trend tests were used to detect the trend in the indices. The results of the trend tests showed that any change is not expected in the total amount of the yearly precipitation amount, whereas the occurrence of the intense and short duration precipitation events is expected to be more probable by the end of the current century, compared to the last 30 years of the previous century. The positive significant trends were detected in some indices. However, the magnitude of the change in the climatic parameters and the increase in the number of extreme precipitation events cannot solely explain the increase in the number of destroying flood events in the province. Other parameters such as the dramatic increase in urbanization as a result of rapid population growth during the past years (since 1960) may have a more prominent effect on the increase of the flood risk in the province which is in need of comprehensive modeling and investigation.
