PEYZAJ KARAKTERİ İLE ÇIĞ DİNAMİKLERİNİN ENTEGRASYONU: 2024 BİNGÖL YENİSU ÇIĞ OLAYI ÜZERİNE BİR DEĞERLENDİRME

Abstract

Bu çalışma, 2024 yılında ölümlü bir çığ olayının yaşandığı Bingöl Yenisu Köyü’nde, peyzaj karakteri ile çığ dinamikleri arasındaki etkileşimi incelemektedir. RAMMS:: Avalanche modeli ve CBS tabanlı peyzaj karakter analizi entegrasyonu ile kar kalınlığı, akış hızı ve dinamik basınç gibi parametreler mekânsal olarak değerlendirilmiştir. Bulgular, zayıf bitki örtüsüne sahip granitoyid formasyonlu kuzey yamaçlarının en yüksek çığ potansiyeline sahip olduğunu; ormanlık ve tarımsal alanların ise doğal tampon işlevi gördüğünü ortaya koymuştur. Çalışmada “doğa temelli peyzaj stratejileri”, çalışmaların kavramsal bir yaklaşımı olarak değil; bitki örtüsü yoğunluğu, arazi eğimi, topoğrafik eşikler (eğim kırımları ve yüzey pürüzlülüğü), toprak stabilitesi ve mevcut arazi kullanım türleri gibi mekânsal ve ekolojik göstergelere dayalı olarak değerlendirilmiştir. Sonuçlar, bu göstergelere dayalı peyzaj temelli yaklaşımların çığ riskinin azaltılmasında ve dağlık alanlarda ekolojik dayanıklılığın güçlendirilmesinde etkili bir planlama aracı olabileceğini göstermektedir.

INTEGRATING LANDSCAPE CHARACTER AND AVALANCHE DYNAMICS: AN ASSESSMENT OF THE 2024 YENISU AVALANCHE EVENT, BİNGOL

Abstract

This study investigates the interaction between landscape character and avalanche dynamics in Yenisu Village (Bingöl, Türkiye), where a fatal avalanche event occurred in 2024. By integrating the RAMMS::Avalanche model with GIS-based landscape character analysis, key parameters including snow depth, flow velocity, and dynamic impact pressure were spatially evaluated. The results reveal that north-facing slopes underlain by granitoid formations and characterized by sparse vegetation exhibit the highest avalanche susceptibility, whereas forested and agricultural landscape units function as effective natural buffering systems. In this study, nature-based landscape strategies are not treated as purely conceptual approaches, but are operationalized through spatially explicit and ecologically grounded indicators, including vegetation density, terrain slope, topographic thresholds (slope break zones and surface roughness), soil stability, and existing land-use/land-cover patterns. The findings demonstrate that landscape-based, nature-driven planning approaches grounded in these indicators can serve as effective tools for reducing avalanche risk and enhancing ecological resilience in mountainous environments.
