LOVRIC N., TOSIC R., 2016. assessment of bank erosion, accretion and lateral channel migration using remote sensing and Gis: case study -Lower part of the Bosna river. Quaestiones Geographicae 35(1), Bogucki Wydawnictwo Naukowe, Poznań, pp. 81-92, 4 fi gs, 4 tables.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 identifi ed that the total area of bank erosion during given period equalled 8.3430 km 2 , of which 3.2593 km 2 were on the left bank and 5.0837 km 2 on the right bank. The total area of bank accretion from 1958 to 2013 equalled 10.7074 km 2 , of which 5.4115 km 2 was on the left bank and 5.2958 km 2 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 signifi cant for practical issues such as predicting channel migration rates for engineering and planning purposes, soil and water management.
