  • Preliminary regional landslide susceptibility assessment using limited data

    Igor Peshevski, Milorad Jovanovski, Biljana Abolmasov, Jovan Papic, Uroš Đurić, Miloš Marjanović, Ubydul Haque, Natasha Nedelkovska (2019)
    In this paper a heuristic approach for preliminary regional landslide susceptibility assessment using limited amount of data is presented. It is called arbitrary polynomial method and takes into account 5 landslide conditioning parameters: lithology, slope inclination, average annual rainfall, land use and maximum expected seismic intensity. According to the method, in the first stage, a gradation is performed for each of the carefully selected conditioning parameters by assigning so called rating points to the grid cells on which the ...

Extraction of a particular land- slide conditioning parameter and repetition of the validation pro- cess is one approach to test model sensitivity (LEE & TALIB, 2005; GUZZETTI et al., 2006).

    ... Total Landslide Susceptibility Rating (TLSR) model is obtained by summing the individual rating points of each parameter and divid- ing the region into five susceptibility zones according to Jenks natural breaks classification. Ver- ification of the TLSR model is then performed by overlaying the landslide ...

    ... Belgrade in Serbia, has been holding over a hundred years the gypsum model of triangular shape that represents the replica of one of the world’s largest native gold nugget weighing 36.2 kg, known as “The Great Triangle”. Nugget model is golden metallic in colour with a shape similar to a rectangular ...
