When modelling flow and/or sediment transport in streams and rivers, one must frequently use the computer software of differing levels of complexity. The level of sophistication, accuracy, and quality of results are the parameters by which models can be classified as being 1D, 2D, or 3D; it seems certain that in the future, there will also be 4D an...

Silting is the main factor limiting the ability to perform the tasks that small reservoirs are intended for. Therefore, the change in sediment trap efficiency was studied for a small shallow reservoir, Krempna, which, due to high silting intensity, was desilted twice (2005, 2018). Siltation measurements were performed in two periods (1987-2005, 200...

In deeply incised rivers, bankfull discharge (i.e. the flow filling the channel to the top of the banks) does not represent channel forming flow and increasingly large flows are associated with increasingly large boundary shear stress. In such rivers, solid bank revetments (rip-rap, gabions, retaining wall) are usually constructed to the top of the...

In the years 2007-2016 about 8,000 new large dams were constructed all over the world. It is widely known that dams disturb abiotic and biotic components of the fluvial systems, but to date the knowledge of their impacts has been mainly derived from observations of downstream river reaches. In contrast, little is known on the biogeomorphological ad...
Most of the studies present in the literature deal with block ramps located in straight channels. This is an evident limitation not allowing for a generalization of laboratory model findings. Generally, these structure typologies are located in natural rivers, that are characterized by both quasi-straight branches and bends. In particular, the loca...

instead of other hydra...
Despite the occurrence of many low head hydraulic structures in rivers, such as drop hydraulic structures
or boulder ramps, there is still a lack of information on how these structures influence stream habitat
conditions and biological communities. This lack of knowledge especially applies to baffled chutes, which,
to date, have not been the subjec...
Because of long-lasting sediment starvation, channel reaches downstream of dams are typically deeply incised and thus the sediment flushed out from the demolished or lowered dams may not be trapped in these reaches but transported far downstream. To enable entrapment of sediment in such a deeply incised channel, artificial boulder ramps were constr...
