The channel, floodplain and terraces are formed primarily through the erosion, transport and deposition of sediment by streamflow. The aim of the paper is to es-tablish the changes at the gauging sections caused by riverbed erosion. The erosion process is evaluated on the basis of minimal annual water stages in gauging station. Minimal annual water stages correspond to the changes of river-bed level. On the basis of 90 years of low stages for gauging stations: Krościenko and Żabno on the Dunajec River, the erosion trends and intensity of cross-section changes are esta-blished. The computation results are compared with the quantity of real changes at gauging sections which are measured in different years. The problem presented in this paper is important in engineering. The knowledge of river-bed changes is ne-cessary when designing water intakes, bridges, etc. It is also connected with deter-mination of the location of underground water in the adjacent area, which is very important for evaluation of the water regime in the soil.
