Assessment of Bank Erosion, Accretion and Channel Shifting Using Remote Sensing and GIS: Case Study – Lower Course of the Bosna River

Abstract River bank erosion, accretion and lateral channel migration are the most important geomorphological processes, which attract a great deal of attention from river engineering scientist over the last century. in the presented study, we assessed how the river’s shape and position have changed during 1958-2013 period using remote sensing and GIS. We have identified that the total area of bank erosion during given period equalled 8.3430 km2, of which 3.2593 km2 were on the left bank and 5.0837 km2 on the right bank. The total area of bank accretion from 1958 to 2013 equalled 10.7074 km2, of which 5.4115 km2 was on the left bank and 5.2958 km2 on the right bank. The Bosna riverbed average movement in the period 1958-2013 was established in the amount of 132.4 m. During this period, the average lateral channel migration was 2.5 m per year. The data presented here are significant for practical issues such as predicting channel migration rates for engineering and planning purposes, soil and water management.

Landslide susceptibility zonation: A case study of the Municipality of Banja Luka (Bosnia and Herzegovina)

Along with flash floods, landslides are one of the most widespread and damaging natural hazards in Bosnia and Herzegovina. This paper determines areas susceptible to landslides in the Municipality of Banja Luka (Republika Srpska, northwest Bosnia and Herzegovina). Based on a terrain survey in a 55.4 km2 area, 216 landslides were identified with a total area of 2.9 km2 or 5.2% of the municipality. According to landslide susceptibility modeling, low susceptibility is present from one-quarter to one-half of the territory and very high susceptibility is present from several percentages up to one-third of the territory, depending on the model used. The results may support government mitigation programs and help in developing a landslide hazard and risk assessment model for the area.

Floods in Serbia in 2010 – Case Study: The Kolubara and Pcinja River Basins

Riverine and torrential floods are the most significant natural hazards on the territory of Serbia. The potentially flooded area in Serbia with a 100-year return period is 15,198.07 km2 (17.2% of total area). Serbia is mostly threatened by the floods of small to medium-size torrential rivers mostly in late spring (from May to the end of June), a period characterised by intensive rainfalls of a few-hour duration. In the Pcinja River Basin, the town of Trgoviste was struck by a flood in May 2010. Two people were killed, almost 170 ha of land and 27 buildings were flooded (including 12 severely damaged), roads damaged or blocked, and 230 inhabitants evacuated. The flood in the Kolubara River Basin of late June 2010 affected 500 ha with 230 flooded households. Total damage was estimated at €370,000. In the watersheds studied, the 2010 floods were natural occurrences, but human action significantly aggravated the disasters. The messages to be learned help improve the system of prevention and the organisation of mitigation of flood damages, in order to reduce it to an acceptable level.
