Article Citation - WoS: 1Citation - Scopus: 1Traditional Water Harvesting Systems in Climate Change Adaptation: Insights From a Semi-Arid Mediterranean Village(Middle East Technical Univ, 2025) Gercek, Deniz; Yuceer, Hulya; Gonulal, Yasemin Ozcan; Ustuk, Ozan; Uzelli, Taygun; Guler, Selen; Baba, AlperTraditional water harvesting systems (WHS), developed over centuries by past civilizations, have long played a crucial role in addressing water scarcity in semi-arid regions. Although these systems have been largely neglected with the expansion of modern water infrastructure, they remain a valuable heritage containing significant knowledge and practices that are still relevant today, particularly in overcoming water management challenges in the face of climate change. Although traditional WHSs have been studied across various regions, their forms and functions vary significantly due to unique climatic, geological, and cultural conditions. In the Mediterranean context, small-scale WHSs have received comparatively limited attention-particularly studies that integrate both their revitalization for contemporary use and their historical and cultural significance. This study aims to help bridge that gap and contribute the existing literature by focusing on the WHSs in Barbaros, a semi-arid village on the Aegean coast of Turkey. Barbaros is particularly unique due to its special geological conditions, as the porous soil makes water retention difficult, which adds to the importance of traditional WHSs. In this context, the main objective of this research is to comprehensively assess these systems, by considering the area's topography, geological features, WHS construction techniques, and local knowledge transmitted across generations. This multidisciplinary approach, combining a literature review, field observations, expert surveys and interviews with long-time residents, enables a comprehensive analysis of the typologies, current state and socio-cultural evolution of these systems. A thorough understanding of these systems is essential to assess their resilience and relevance for climate change adaptation, especially with regard to drought management. The study concludes that, despite their partial abandonment, the traditional WHSs in Barbaros offer valuable insights into sustainable water management and demonstrate their potential as practical models for addressing today's water challenges.Article KOCAELİ İZMİT İLÇESİ’NDE PARTİKÜL MADDE (PM2.5) KONSANTRASYON SEVİYELERİ, MEKÂNSAL VE MEVSİMSEL DEĞERLENDİRİLMESİ(2021) Öztürk, Süheyla; Gerçek, Deniz; Güven, İsmail Talih; Gaga, Eftade O.; Üzmez, Özlem Özden; Civan, Mihribanİzmit İlçesi’nde yaz (Temmuz 2018 - Eylül 2018) ve kış mevsimlerinde (Kasım 2018 - Ocak 2019) yüksek hacimli örnekleyici kullanılarak partikül madde (PM2.5) derişimleri ölçülmüştür.

Turkey is one of the most at-risk countries for earthquake disasters worldwide. Therefore, it is imperative to develop effective earthquake vulnerability assessment and mapping at practically relevant scales. In this study, a holistic earthquake vulnerability index that addresses the multidimensional nature of earthquake vulnerability was constructed. With the aim of representing the vulnerability as a continuum across space, buildings were set as the smallest unit of analysis. The study area is in Izmit City of Turkey, with the exposed human and structural elements falling inside the most hazardous zone of seismicity. The index was represented by the building vulnerability, socioeconomic vulnerability, and vulnerability of the built environment. To minimize the subjectivity and uncertainty that the vulnerability indices based on expert knowledge are suffering from, an extension of the catastrophe progression method for the objective weighing of indicators was proposed. Earthquake vulnerability index and components were mapped, a local spatial autocorrelation metric was employed where the hotspot maps demarcated the earthquake vulnerability, and the study quantitatively revealed an estimate of people at risk. With its objectivity and straightforward implementation, the method can aid decision support for disaster risk reduction and emergency management.Article Perceived Safety and Affecting Factors in Urban Neighborhoods(Süleyman Demirel, 2021) Gerçek, Deniz; Güven, İsmail TalihThis study intends to explore how various aspects of safety such as criminal acts, public order, and sense of community contribute to ‘perceived safety’. A questionnaire was applied to 1050 individuals that comprise the sample set living within the urban sprawl of İzmit city. People were asked to rate their evaluations on a set of safety issues in the neighborhood they live, such as crime acts, public disorder, community relationships. Investigating relevance of these issues versus perceived safety is important to understand characteristics of perceived safety in an urbanizing city subject to industrialization and immigration. Primary demographic variables: gender, age, income, and education level were also explored for their relation with perceived safety in the city. Using the quantitative method of surveying and statistical analysis, several outcomes were inferred. Accordingly, perceived safety in the city is highly associated with peoples’ opinion about crime incidences and other safety and public order issues. Community attachment has a moderate influence on perceived safety, where more connected communities are likely to feel more safe. Descriptive statistics and tests showed that perceived safety with respect to gender differs, where female feel less safe. Perceived safety versus education level and income also showed some sort of relation pattern. However, this was attributed to the fact that poor and disintegrated urban neighborhoods are more likely to suffer from crime, rather than poverty brings lack of feel of safety.Using the quantitative method of surveying and statistical analysis, several outcomes were inferred.

The UHI effect shows substantial intra-urban variation at the city microscale, causing disparities in thermal comfort and energy consumption. Therefore, air temperature assessment should be prioritized for effective heat mitigation and climate adaptation. However, meteorological stations’ spatial distribution is far from meeting the scale that the UHI and its driving parameters operate. This limitation hampers demonstrating the intra-city variability of UHI and its origin of sources; for example, most studies employ Land Surface Temperature (LST), usually without demonstrating the relationship between UHI and LST. The current body of knowledge on urban climate implies a much better understanding and more detailed information on the spatial pattern of UHI and the driving factors to provide decision-makers with tools to develop effective UHI mitigation and adaptation strategies. In an attempt to address the adequacy of the use of LST and UPs in describing the intra-city variability of UHI, this study investigates the relationship between LST daytime and nighttime, and air temperature (Ta) daytime and nighttime, and driving urban parameters (UPs) of UHI together. Although it is well recognized that the intensity of the UHI is characterized by Ta, particularly at night, so-called nocturnal UHI, the use of remotely sensed LST is common, owing to the lack of spatially detailed Ta data in cities. Our findings showed that nocturnal UHI is weakly correlated with nighttime LST with a Pearson correlation (r) of 0.335 at p > 0.05 and that it is not correlated with daytime LST for the case study, highlighting the need for Ta observations for representing the intra-urban variation of nocturnal UHI. Among UPs, Sky View Factor (SVF), Building Volume Density (BVD), and Road Network Density (RND) explained 69% of the variability of Ta nighttime that characterizes nocturnal UHI. Therefore, UPs that performed well in estimating nocturnal UHI may be used in the absence of densely distributed Ta measurements. In a further investigation of the urban cooling phenomenon based on UHI diurnal changes, a particular region with high nighttime temperatures spoiled the Ta daytime and nighttime coherence. This region is characterized by high Mean Building Height (MBH), BFD, and BVD that re-emits heat, low SVF that prevents urban cooling, and high RND that releases extra heat at night. These particular UPs can be of prior interest for urban cooling. The present study, exploring the relationships of LST and Ta in a diurnal context, offers a further understanding of the preference of LST, Ta, or UPs to characterize UHI. Ta, in relation to major causative factors (UPs), provides insights into addressing the localities most vulnerable to the UHI effect and possible strategies targeting heat mitigation for sustainability and climate change resilience. © 2023 by the authors.Article Citation - WoS: 6Citation - Scopus: 6Valuing Groundwater Heritage: the Historic Wells of Kadıovacık(Springer, 2021) Yüceer, Hülya; Baba, Alper; Özcan Gönülal, Yasemin; Uştuk, Ozan; Gerçek, Deniz; Güler, Selen; Uzelli, TaygunThe consideration of the subject of water resources, seen as a part of cultural heritage, generally includes water-related architectural structures such as bridges, aqueducts, and cisterns. Groundwater resources and related structures, however, receive little attention as heritage assets, and they are mostly forgotten together with the valuable information they hold. In this sense, this study aims to provide an accurate assessment of groundwater heritage and to suggest proposals for conservation through the case of the historic wells of Kadıovacık village in the Urla district of İzmir. Although the region where the village is located is rich in groundwater resources, the residents have suffered from drought for ages due to the specific geological characteristics of the Kadıovacık polje. The limited amount of water resources in Kadıovacık village have karstic characteristics and have shaped the life and topography of the region. To access and harvest this limited groundwater, a group of wells had been constructed on the ridge of the hill. These wells have been idle since 1980s with the supply of city main water. In line with the aim, a comprehensive heritage valuation by an interdisciplinary group of experts is essential to reveal the significance of the relatively humble wells. Accordingly, a multi-method system is used, including historical, social, cultural, architectural, geological, hydrogeological, and environmental aspects. The results show that although the wells are generally considered to be less important as heritage assets in terms of their physical features, an in-depth evaluation demonstrates their high significance for the village community.
