Coasts are important areas where the vast majority of the world's population lives, have important natural resources and ecosystems, and provide socio-economic opportunities for societies. However, coastal areas are under threat due to different natural disasters such as storms, tsunamis and floods that cause loss of life and property. With the rapid development of hardware and software technologies, many programs that play an important role in the assessment of the natural disasters have achieved to perform high level numerical modeling. In this thesis, Benchmark Problems of the National Tsunami Hazard Mitigation Problems (Benchmark Problem 2, Tohoku tsunami in Hilo harbor Hawaii and Benchmark Problem 4, Seaside Oregon State University Experiments) are simulated with NAMI DANCE and DELFT3D numerical models. The results of the models are compared with the field and experimental data. It is seen that the computed results are in fairly well aggrement with the field and experimental data. Furthermore, the tropical cyclone Dorian occurred in the western Atlantic and Caribbean in September 2019 was simulated by the numerical model NAMI DANCE with its new module solving tropical cyclone events. The numerical results have also been compared with the observations and records at different locations in Caribbean and Western Atlantic coasts.

Assessing the impacts of climate change on sustainable management of coastal aquifers UNSAL, Burcu; Yagbasan, Ozlem; Yazıcıgil, Hasan (2014-09-01) Water is a vital resource for the survival of not only human population, but also almost all ecosystems. Constituting 30 % of all freshwater, groundwater is the main source of available freshwater. Coastal aquifers, which serve as the major freshwater source for densely populated zones, are of vital importance and quite vulnerable to climate change. This paper examines the significant consequences of climate change, decreasing recharge rates, sea-level rise and increasing freshwater demand on the sustainabl...
Evaluation of the best management practices in a semi-arid region with high agricultural activity Özcan, Zeynep; Kentel Erdoğan, Elçin; Alp, Emre (Elsevier BV, 2017-12) The arid and semi-arid regions with water scarcity are vulnerable to several stressors such as urbanization, high water demand created by agricultural and industrial activities, point and non-point pollution sources, and climate change. Hence, proactive policies and sustainable water management strategies that are based on decision support systems are crucial in arid and semi-arid regions. Because of large expenses and implementation difficulties associated with the diffuse pollution abatement plans, many a...
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 ...
Danish and other European experiences in managing shallow lakes Jeppesen, Erik; Sondergaard, Martin; Lauridsen, Torben L.; Kronvang, Brian; Bekiloglu, Meryern; Lammens, Eddy; Jensen, Henning S.; Koehler, Jan; Ventela, Anne-Mari; Tarvainen, Marjo; Tatrai, Istvan (2007-12-01) For a century eutrophication has been the most serious environmental threat to lakes in the densely populated or agricultural areas of Europe. During the last decades, however, major efforts have been used to reduce the external nutrient loading, not least from point sources. Despite these comprehensive efforts, lake eutrophication remains a major problem. Today, the highest pollution input is derived from diffuse sources mainly from agricultural land in lake catchments. We describe the actions taken to red...
Evaluation of Walkability and Pedestrian Level of Service Tüydeş Yaman, Hediye (2018-01-01) Due to decreasing resources, living in urban regions focus on sustainability in many aspects, including transportation. Sustainable transportation encourages non-motorized modes of walking and cycling as well as public transit (which also relies on walking while accessing a station), as well. However, walking as a mode is still a big mystery itself that needs further attention and research effort especially in the evaluation part. So far, the planners have discussed the concepts of walking and walkability, ...
