Chronic seismic hazards and resulting secondary impacts as natural conditions of the country, and the loss of robust building and prudent settlement practices as aggravated by rapid population growth make cities the most vulnerable geographical and social entities in Turkey. For the development of risk reduction policies, an essential step is to prioritize settlements according to their vulnerability levels. This could be determined by hazard probabilities and attributes of the building stock of each settlement. Measurement of vulnerability levels allows the ordering of settlements into risk categories. Vulnerability levels of settlements are then assumed to depend on a number of attributes of cities to explore whether vulnerability could be related to a set of urban properties. Results of statistical analyses indicate that total building loss is related to the ratio of population over the total number of buildings in mid-range settlements, and directly related to population in metropolitan cities. Relative loss on the other hand is related with the rate of agglomeration and development index in almost every size category of settlements. Observations provide guiding principles for effective mitigation practices in Turkey by ordering settlements and offer means of differential implementation. These could contribute to improved safety measures in urban standards, building codes, building supervision procedures, insurance systems, and investment priorities.

Seismic vulnerabilities and risks for urban mitigation planning in Turkey Sönmez Saner, Tuğçe; Ersoy, Melih; Balamir, Murat; Department of City and Regional Planning (2013) Chronic seismic hazards and resulting secondary impacts as natural conditions of the country, and loss of robust building and prudent settlement practices as aggravated by rapid population growth make cities the most vulnerable geographical and social entities in Turkey. In contrast, Turkish disaster policy is solely focused on post-disaster issues and no incentives or provision exist to encourage risk analysis or risk mitigation approaches, despite current international efforts. For the development of risk...
ANALYZING THE RELATIONSHIP BETWEEN DISASTER RISK MITIGATION AND URBAN PLANNING PROCESSES: THE CASE STUDY OF ESKISEHIR CITY Sert Özkiremitçi, Merve; Balaban, Osman; Department of City and Regional Planning (2022-5-11) The aim of this study is to discuss the effectiveness and efficiency of urban planning in reducing the risk of natural disasters in cities and to analyse the relationship between planning and disaster mitigation processes. The study focuses particularly on the analysis of Eskişehir case with reference to data and information on disaster risk analysis, existing urban development plans as well as the plan implementation processes. After the 1999 Gölcük and Düzce Earthquakes, Eskişehir has also faced and to a ...
Contamination risk assessment for groundwater of the Kucuk Menderes River basin, Izmir, Turkey Pusatli, OT; Camur, MZ; Yazıcıgil, Hasan (2000-04-01) A new water management plan is needed for the Kucuk Menderes River basin in Turkey, due to increasing water demand and decreasing quality of the groundwater. Vulnerability, quality and risk assessments were performed using a hybrid model containing both hydrogeological and hydrochemical parameters for managing irrigation waters in the basin. The relative contamination (quality) distribution of groundwater at present was established using an irrigation water quality index. The distribution shows the contamin...
Seismic response of hunchbacked block type gravity quay walls Yuksel, Z. Tugce; YÜKSEL, Yalçın; Çetin, Kemal Önder; ÇEVİK, Esin (2017-10-01) Earthquakes near major cities may cause big social and economic impacts. Damages to port facilities may cripple the economy. The past twenty years' experience has proven the high vulnerability of the port facilities. This fact, along with the economic importance of port structures, indicates the need for better seismic design approaches for berth structures and cargo handling facilities. In the recent decades, there have been many incidences of failure of gravity type quay walls. These failures have stimula...
Urban disaster risk management with compulsory earthquake insurance in Turkey Taylan, Arzu; Balamir, Murat; Werner, Ute; Department of City and Regional Planning (2009) Turkish Compulsory Earthquake Insurance (ZDS) introduced after the 1999 Earthquakes aimed to lower financial burdens of the State and to promote safer building construction. High earthquake risk in Turkey necessitates risk mitigation, in line with the priority of the new international policy. Yet, the ZDS system operates without regard to risk mitigation, and it is far from being a compulsory condition. The ZDS system has low penetration ratios due to expectations of State-aid in the event of a disaster, wh...
