- Abstract: Large alluvial rivers are often subject to changes in their planform, channel form (cross sections), and longitudinal profile of their channels; also due to human interventions such as river navigation and flood protection works. We have shown such temporal changes in two severely modified reaches of the gravel-bed river Sava, the largest river in Slovenia (11,735 km2). The Ljubljanska Sava has significantly changed since the 19th century until today and this is largely due to long-term regulation of its channel, and later due to construction of hydroelectric power stations upstream of this section. The Lower Sava River, downstream of the confluence with the Savinja River, is severely modified due to regulation works and in the last years due to hydro power plants, in the reach at the Nuclear Power Plant Krško also due to the Krško weir. This study contributes to the understanding of fluvial processes when assessing the Sava River sediment budget, especially at the cross section with the Republic of Croatia.
