Assessment of torrential flood and landslide susceptibility of terrain: Case study - Mlava River Basin (Serbia)

Abstract

Torrential floods and landslides are frequent natural disasters in Serbia, but also in the Mlava River Basin. Due to the large number of settlements, the main goal of this research is to determine the locations that are most susceptible to torrential floods and landslides in the Mlava River Basin. Using geographic information systems (GIS), the first step is the analysis the susceptibility of the terrain to torrential floods using the Flash Flood Potential Index (FFPI) method. According to the obtained data, it was determined that 31.53% of the Mlava River Basin is susceptible, and 10.46% is very susceptible to torrential floods. The second step is the analysis of the susceptibility of the terrain to landslides, for which the statistical Probability method (PM) and the Landslide Susceptibility Index (LSI) were used. According to the results of the LSI index and PM method, 8.09% and 14.04% of the basin area is in the category of high and very high susceptibility to landslides. This paper represents a significant step towards a better understanding of unfavorable natural conditions in the Mlava River Basin, and the obtained results are applicable to numerous human activities in the research area (environmental protection, sustainable management of agricultural plots, protection of water and forest resources and ecosystems, etc.).

Determination of Flash Flood Hazard Areas in the Likodra Watershed

“…In the territory of the Republic of Serbia, using the FFPI method, the basins of the Ljig, Kolubara, Jošanica, Ibar, South Morava, and Danube torrents in Serbia (from Požarevac to Negotin), Mlava, and Timok rivers were analyzed [27,29,30,[58][59][60][61][62]. Figure 8 illustrates the percentage representation of FFPI susceptibility classes.…”

GIS application in analysis of threat of forest fires and landslides in the Svrljiski Timok basin (Serbia)

“…Кључне речи: ГИС, шумски пожари, клизишта, слив Сврљишког Тимока, животна средина Увод У 21. веку човечанство се све чешће суочава са природним катастрофама и њиховим последицама по животну средину. Прекомерна експлоатација природних ресурса, климатске промене, природне непогоде, неадекватно управљање отпадом и губитак биодиверзитета широм планете представљају велике изазове за човечанство (Lerner, 2007;Lukić et al, 2021;Durlević, 2021).…”

“…In the XXI century, humanity is increasingly facing natural disasters and their consequences for the environment. Excessive exploitation of natural resources, climate change, natural disasters, inadequate waste management and loss of biodiversity across the planet represent major challenges for humanity (Lerner, 2007;Lukić et al, 2021;Durlević, 2021). The territory of the Republic of Serbia is endangered by various natural disasters: earthquakes, landslides, avalanches, torrential floods, droughts and forest fires.…”

GIS-Based Spatial Modeling of Snow Avalanches Using Analytic Hierarchy Process. A Case Study of the Šar Mountains, Serbia

“…As indicated by Gruber and Bartelt [30], potential avalanche release areas are strongly related to the slope inclination of the terrain in general. Therefore, GIS and remote sensing based techniques can be used to automatically and efficiently determine potential avalanche release areas and other natural hazards [31][32][33][34][35][36][37][38][39][40][41][42].…”
