Slope movements and erosion phenomena in the Dubračina River Basin: A geomorphological approach

This paper presents results of mapping of active geomorphological processes at the area of the Dubracina River Basin. Regarding to geological settings, geomorphological features and hydrological conditions, different landform units were outlined and are characterized by typical types of slope movement and erosion phenomena. Remote sensing represents a valuable tool for the identification and mapping of active geomorphological processes for the whole investigated area. Available remote sensing data for the Dubracina River Basin were stereopairs of aerial photographs from 2006 and high resolution DEM derived from the airborne LiDAR survey conducted in March 2012. Visual interpretation of aerial photographs and LiDAR imagery was undertaken with the aim to derive landform classification map presenting different landform units with typical types of slope movement and erosion phenomena. It is evident that each landform unit has its unique type of hazardous active geomorphological processes. Presented analysis will be used as a base for development of a methodology for multihazard inventory map preparation of the Dubracina River Basin.
