EFFECT OF THE CURVATURE PARAMETER AND İTS CLASSİFİCATİON ON LANDSLİDES

Abstract

The first question that generally comes to mind about the curvature parameter is whether this parameter is suitable for the study area. This question uses every parameter to be asked, but some effects that are implemented incorrectly, such as curvilinearity, raise question marks. As a result of technical errors and conceptual confusion regarding the parameter, the landslide area defined as concave by one researcher may be defined as convex by another researcher. For this reason, some researchers state that they contradict the literature and produce results contrary to their expectations. Due to such negativities, there is no consensus in the literature regarding curvilinearity parameters. This determination was used for 64 areas selected for curvature parameters in three different classes and the prices of their changes in total. By examining the maximum and minimum distributions in the landslide area, it was investigated what kind of change it caused in concave, convex and flat areas depending on the terrain. As a result of the analysis, it was revealed that class intervals that could not be determined correctly resulted in cracks in the landslide capacity proportional distributions. Thus, the study achieves the main goal that will facilitate the use of the curvature parameter.

EĞRİSELİK PARAMETRESİ VE SINIFLANDIRILMASININ HEYELANLARA ETKİSİ

Abstract

Eğrisellik parametresini seçerken akla gelen ilk soru, bu parametrenin çalışma alanına uygun olup olmadığıdır. Genellikle bu soru kullanılan her parametre için sorulur, ancak eğrisellik gibi uygulama hatası yapılan bazı parametreler soru işaretlerine neden olur. Parametre ile ilgili yapılan teknik hatalar ve kavram karmaşası sonucu, bir araştırmacı tarafından içbükey olarak tanımlanan heyelanlı alan, diğer bir araştırmacı tarafından dış bükey olarak tanımlanabilmektedir. Bu nedenle bazı çalışmalarda, araştırmacılar literatürle çelişmekte ve kendi alanlarının beklentilerinin aksine sonuçlar verdiğini belirtmektedir. Bu gibi olumsuzlular nedeniyle, eğrisellik parametresi konusunda literatürde fikir birliği sağlanamamaktadır. Yapılan bu çalışmada seçilen 64 alan için üç farklı sınıftaki eğrisellik parametresi kullanılmış ve bunların toplamdaki değişimleri incelenmiştir. Heyelanlı alandaki maksimum ve minimum dağılımlar incelenerek bunun araziye göre içbükey, dışbükey ve düz alanlarda nasıl bir değişime neden olduğu araştırılmıştır. Analizler sonucunda, doğru belirlenmeyen sınıf aralıklarının, heyelan alanlarının oransal dağılımlarında farklılıklar çıkarttığı ortaya çıkmıştır. Böylece çalışma ana hedefine ulaşarak, eğrisellik parametresinin kullanımını kolaylaştıracak ip uçları vermiştir.
