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

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.
