Sažetak
Permanent changes of channel geometry is one of the major river characteristics. They occur in more or less stabilized boundaries with direction to dynamic balance. Human activities have a large contribution in modification of this dynamic balance. In large Croatian rivers modification of river bed geometry are clearly caused by human activities. Due to stabilized river banks, geometric changes are indicated in river bed degradation. This paper gives analysis of channel depth changes in transfer zone of river Sava and channel depth changes in depositional zone of river Drava. Both rivers are navigable on these sequences, and channel geometry changes have a large impact on navigability purpose. On river Sava additional issue is water level degradation which causes troubles in use of rivers. It is possible to make strong relation between river bed degradation and water-level degradation. Additional river bed degradation is caused by gravel exploitation and dredging for increasing waterway depth. This paper gives critical review with recommended actions to lower negative impact of river bed degradation on water regime.
