Along with socioeconomic developments, and population increase, natural disasters around the world have recently increased the awareness of harmful impacts they cause. Among natural disasters, drought is of great interest to scientists due to extraordinary diversity of their severity and duration. Motivated by developing a potential approach to investigate future possible droughts in a probabilistic manner based on climate change projections, a methodology to consider thirteen future climate projections based on four emission scenarios to characterize droughts is presented. The proposed approach uses a hydro-climate model (watershed environmental hydrology hydro-climate model; WEHY-HCM) to generate equally likely thirteen future water supply projections. The water supply projections were compared to current water demand for detection of drought events and estimation of drought properties. The procedure was applied to Shasta Dam Watershed to analyze drought conditions at the watershed outlet, Shasta Dam. The results suggest an increasing water scarcity at Shasta Dam with severer and longer future drought events. This study presents an advantage of the future probabilistic structure in drought analysis by providing drought properties of the 100-year and 200-year return periods without resorting to any extrapolation of the frequency curve.

Assessment of recently developed inner city neighborhoods according to sustainable urban planning and design criteria: the case of Çukurambar
Köken, Kayhan; Şenyel Kürkçüoğlu, M. Anıl.; Urban Design in City and Regional Planning Department (2019)
The world population is increasing rapidly while the most significant effects can be observed in cities. Environmental, economic and social problems are increasing continuously along with this urban growth. Classical urban planning and design approaches are no longer sufficient to address these problems. Thus, more sustainable methods are being developed to solve them. Sustainable development concept addressing current environmental, economic and social issues are on the agenda of Turkey, similar to the wor...
Sensitivity analysis of 2-D flood inundation model LISFLOOD-FP with respect to spatial resolution and roughness parameter
Kıyıcı, Ezgi; Akyürek, Sevda Zuhal; Department of Civil Engineering (2019)
One of the most common disasters in the world is flooding and it’s well known that it causes environmental, social and economic damages. Since these damages could be severe and destructive due to drivers such as climate change and humane factors, the necessity of flood management studies is revealed. Europe has recognized the need for creating flood risk maps and flood hazard maps. 1-D and 2-D hydraulic models have been used to obtain these maps. This study is focused on the sensitivity of a 2-D hydraulic m...
Adaptation and validation of the sustainability consciousness questionnaire for teacher candidates
Güler, Fulden; Şen, Mehmet; Özdemir, Mine; Öztekin, Ceren (2018-09-07)
There are several problems encountered in developing countries such as rapid population growth, deforestation, urbanization and these problems lead to consumption of natural resources (UNESCO, 2006). The term sustainable development (SD) is highlighted in the last decades to deal with the problems of the globalized world. One of the earlier studies, Brundtland Report (WCET, 1987) defined SD as “development that meets the needs of the present generation without compromising the ability of future generations ...
Evaluation of the accuracy of equivalent linear analysis method for seismic isolated buildings
Mutlu, Sezer; Dicleli, Murat; Department of Engineering Sciences (2021-12-1)
Earthquakes have been the leading cause of loss of lives and properties since the beginning of human history. After major earthquakes, we see that even the buildings constructed using modern engineering solutions suffer severe damage or even collapse. Seismic base isolation systems are used to minimize earthquake-induced damage. This thesis focuses on evaluating the accuracy of the equivalent linear analysis method in the analysis of seismic base-isolated buildings. In order to do that, certain buildings wi...
