Slovenia has a contemporary hydrological network of water gauging stations that monitor the situation of the watercourse in near real-time. At the same time, the occasional measurements of discharge are conducted at these stations in order to create and update rating curves. Modern acoustic gauges which have been used in recent years also enable the simultaneous measurement of the geometry of the cross-section.
The present work presents the data analysis of the measurements of cross-sections and the representation of the changes in seven water gauging stations on Savinja river. We compared the variability of the surface of cross-sections with respect to the geodetic image of the river profile of a chosen gauging station was compared and the elevation of the river bottom level at points within the cross-section of the water gauging station.
The results of the analysis show constant changes of the cross-section due to the erosion and accumulation of sediments. We found that most of the largest changes are due to material deposition. However, the obtained results show that the Savinja riverbed is still deepening in a long-term perspective.
