Improvements of Machine Learning-based landslide prediction models can be made by optimizing scale, customizing training samples to provide sets with the best examples, feature selection, etc. Herein, a novel approach, named Cross-Scaling, is proposed that includes the mixing of training and testing set resolutions. Hypothetically, training on a co...

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. Accord...

The main idea of this chapter is to address some of the key issues that were recognized in Machine Learning (ML) based Landslide Assessment Modeling (LAM). Through the experience of the authors, elaborated in several case studies, including the City of Belgrade in Serbia, the City of Tuzla in Bosnia and Herzegovina, Ljubovija Municipality in Serbia...

During the heavy rainfall and associated disastrous floods and massive landslides in 2014, the territory of the the Valjevo City, located in the western Serbia, suffered strong road network issues, particularly landslide‐related effects. Herein, it was attempted to assess critical sections, to propose targeted and systematic actions. The network in...

This paper focuses on modeling rainfall-induced massive landsliding in the Western Serbia in the 2001–2014 period. The motivation for conducting the study was the rainfall-induced flooding and landsliding that took place across most of the Serbia and Bosnia and Herzegovina in May 2014, and had devastating effects, including human casualties, and de...

This paper represents a relative landslide risk assessment of the City of Valjevo in Western Serbia. After the extreme rainfall during the May 2014, many new landslides were triggered, and Valjevo was one of the most affected areas in Serbia. The modeling was preceded by the data selection, and included ranging and preprocessing of the conditioning...

The IPL project No 181 titled “Study of slow moving landslide Umka near Belgrade” started in November 2012. The study area is located on the right bank of Sava River, 25 km south west of Belgrade, Serbia. The basic objective of the Project was to enable the analysis, correlation and synthesis of data obtained from various phases of investigation of...

The IPL project No 210, titled “Massive landsliding in Serbia following Cyclone Tamara in May 2014”, started in March 2016. The study area is located in the Western and Central part of the Republic of Serbia territory affected by Cyclone Tamara in May 2014. The project aims to summarize and analyse all collected relevant data, including historic an...

Construction of E75 highway section through Grdelica Gorge, as part of Pan-European Corridor 10, is one of the most demanding projects to be realised in recent Serbian history. Alignment of length approximately 25km consists of several tens of bridges, two tunnels, three galleries and cuts over 40m high with total length of 4 km. Budget overruns an...

This research addresses surface analysis based on the Terrestrial Laser Scanning data exampled on rockslope site along M-22 highroad near Ljig in Serbia. The slope is about 100 m wide and over 20 m high. The scanning was performed in three epochs 2011, 2013 and 2014, but only the latter two were involved in the analysis due to insufficient quality...

In this research terrestrial LiDAR scanning has been used for building high-resolution point clouds of a rock slope site on the M-22 highroad near Ljig in Serbia. The scanning has been conducted in two epochs in the past two years. The slope is about 100 m wide and 10 m high, and its surface is faceted, so we decided to process only one sample of t...

Performing of the deep excavations leads to an imbalance in the terrain and consequences are frequent occurrences of local sliding, collapse, settlement and even destruction of the adjacent facilities. Therefore, knowledge of the existing engineering geological data is very important, because in urban areas problems of interaction of the new facili...

This paper describes a characteristic landslide model, typically hosted in Neogene formations in Serbia, especially along right banks of the Sava and Danube rivers. It is focused on particular landslide Umka near Belgrade, which is a paradigm to a numerous landslides in that area. Abundance in various field investigations and laboratory tests carri...

Serbia is well known for numerous landslide phenomena. Landslides are particularly notable for the valley walls of the rivers Sava and Danube and their respective tributaries. They have in common the fact that they all originated in complexes of Neogene sediments made of different lithological elements, and most often clays, sands, and marls with p...

Landslide development along the valley banks of the Sava and Danube rivers is linked to the theory of river channel evolution, which encompasses the synchronous evolution of erosion and accumulation processes within the river channels and their impact on the morphological modeling of river banks. Within this process, the evolution of each part of t...
