“…A similar trend is observed for the density of geohazards in the medium susceptibility areas for debris flows, ground subsidence, soil erosion, and sea water intrusion. The Receiver Operating Characteristic (ROC) curve serves as a tool for quantitative analysis to gauge the precision of models, with the Area Under the Curve (AUC) value falling within the range of 0.1 to 1.0 [116,117]. A higher AUC value indicates enhanced model accuracy, with an AUC value of 1.0 signifying optimal accuracy.…”

Geohazards pose significant risks to communities and infrastructure, emphasizing the need for accurate susceptibility assessments to guide land-use planning and hazard management. This study presents a comprehensive method that combines Variable Weight Theory (VWT) with Analytic Hierarchy Process (AHP) to assess geo-environment vulnerability based on susceptibility to various geohazards. The method was applied to the Pearl River Delta in China, resulting in the classification of areas into high vulnerability (5961.85 km2), medium vulnerability (19,227.93 km2), low vulnerability (14,892.02 km2), and stable areas (1616.19 km2). The findings demonstrate improved accuracy and reliability compared to using AHP alone. ROC curve analysis confirms the enhanced performance of the integrated method, highlighting its effectiveness in discerning susceptibility levels and making informed decisions in hazard preparedness and risk reduction. Additionally, this study assessed the risks posed by geohazards to critical infrastructures, roads, and artificial surfaces, while discussing prevention strategies. However, this study acknowledges certain limitations, including the subjective determination of its judgment matrix and data constraints. Future research could explore the integration of alternative methods to enhance the objectivity of factor weighting. In practical applications, this study contributes to the understanding of geo-environment vulnerability assessments, providing insight into the intricate interplay among geological processes, human activities, and disaster resilience.

“…Groundwater level decline rates (WLD) were obtained by calculating the differences in water The receiver operating characteristic (ROC) curve method was used to assess the validity of the MIF analysis that was based on a variety of variables. The ROC method has been applied to a wide variety of environmental datasets and is described in detail by Taheri et al (2021). ROC curve analysis provides a method to differentiate two classes, established through a diagnostic test.…”

“…Perhaps the most common cause of aquifer overexploitation is the lack of adequate or consistent governance in the management of these vital resources resulting in the loss of water supplies. Poor water management also results in creation of environmental stress such as drying of karst springs (Taheri et al 2015a(Taheri et al , 2015c(Taheri et al , 2016, salinization of aquifers (Bagheri et al 2019;Panagopoulos 2021a), brine contamination (Panagopoulos 2020(Panagopoulos , 2021b, land subsidence (Karimi and Taheri 2010;Rezaei et al 2021), sinkhole formation (Taheri et al 2015b(Taheri et al , 2019(Taheri et al , 2021, or aquifer contamination with chemicals, radioactive materials, and combinations of contaminates that cannot be economically remediated, forcing aquifer abandonment. Unsustainable groundwater management impacts current and future populations and in many cases causes irreparable human hardship.…”

The Dehgolan aquifer, which lies in semiarid western Iran, was evaluated using a multi-influencing factor (MIF) analysis to determine groundwater sustainability. Eight indicators, including climatic variability, groundwater exploitation (pumping), groundwater quality, groundwater vulnerability, public participation, legal framework, water productivity, and occupation related to groundwater, were quantified and placed into a series of thematic maps within a GIS framework. Each factor was weighted based on the analyses obtained from the MIF model and the stacked maps were summed to yield a final map showing the degree of sustainability within the groundwater basin. The final groundwater sustainability map showed that 4% of the basin was in a critically unsustainable zone, 30% in an unsustainable zone, 40% in a semisustainable zone, 25% in a sustainable zone, and 1% in an ideally sustainable zone. The final map was validated using a receiver operating characteristic (ROC) method, cross-tabulation, and chi-square tests using groundwater-level decline as a test proxy. The analysis assessed the correlation between water levels that exhibited declines versus the degree of unsustainability of water levels and sustainable water use. The area under the curve was calculated to be 88%, cross-tabulation 64.4%, and the chi-square value was 260.5 with 4 degrees of freedom and values <0.05 (3.627E −55 ), which suggest that the final map has statistical significance. The sustainability analysis developed is useful as a baseline for development of governance laws to implement management methods in groundwater basins and it can be applied to a wide range of aquifer types in variable climates worldwide.

“…Yapay ve doğal boşluklar, yer altı suları veya doğal mağaralar gibi yer altında bulunan yapıların tam anlamıyla tespit edilememesi farklı boyut ve şekildeki obrukların ani oluşmasına ve dolayısı ile çevreye zararın boyutlarını arttırmaktadır [1]. Obruklar, genellikle dolomit ve kireçtaşı gibi kalsiyum karbonatlardan oluşan kayaçların yüzeyde çözünmesinin neden olduğu çöküntüler olduğundan karstik kayaçlı alanlar diğer bölgelere göre daha da savunmasızdır [2]. Özellikle bu gibi bölgelerde yer üstü ve yer altı doğal yapıyı değiştirecek insan faaliyetleri bölgenin savunmasızlığını daha da arttıracaktır [3][4][5].…”

Afetler, can ve mal kayıpları gibi büyük zararlara yol açan beklenmedik ve istenmedik durumlardır. Doğal afetlere örnek olarak deprem, sel, heyelan, erozyon, çığ ve obruklar gösterilebilir. Önemli bir afet türü olan obruklar meydana geldiği alanda ciddi güvenlik sorunları meydana getirmektedir. Tüm dünya da oluğu gibi Türkiye’de de, yeraltı su kaynaklarının giderek azalması, iklim özelliklerini hesaba katılmadan yapılan yoğun tarımsal faaliyetler ve bunlara ek olarak ilgili bölgelerin jeolojik yapısı gibi faktörler obruk oluşma riski bulunan alanlarda sorunlar ortaya çıkarmaktadır. Mal ve can kaybına yol açan, kontrol edilemeyen ve aniden gelişen obruk olaylarını tamamen engellenemese de, önlem alabilmek mümkündür. Bu çalışmanın amacı Aksaray ilinde hızla sayısı artan obrukların mekansal olabilirliğini tahmin eden ve gösteren duyarlılık haritalarının oluşturulmasıdır. Obruk duyarlılık haritalarının oluşturulmasında Coğrafi Bilgi Sistemleri (CBS) ve Analitik Hiyerarşi Süreci (AHS) yöntemi kullanılmıştır.
