Large wood (LW) can exert strong influence on sediment storage patterns in fluvial systems. However its specific impact routing is largely dependent the stability of individual LW pieces or jams. We used (dis)connectivity principles to quantify erosion and along a meandering river reach. Decadal spatiotemporal changes landforms are appraised 3.65 km long reach Odra River (Czechia). Detailed orthophotos at two-year intervals from 2012 2022 analysed alongside field inventories. During this...
Abstract The grain sizes of 53 small lateral and mid‐channel deposits were evaluated on the 2.7 km long channel‐reach a headwater piedmont stream that has been affected by check‐dams bed sills constructions (ca. 14 per km), riprap bank stabilisations removal instream wood. Such interventions have led to loss natural vertically oscillating bedforms, pool‐riffles replaced plane beds. sediment divided based their positions relative grade‐control structures downstream, intermediate upstream...
Abstract The links between rapid channel degradation and related large wood (LW) recruitment storage are still not precisely understood, especially in aquatic systems with high human natural pressures such as intermittent rivers the peri‐Mediterranean region. In this study, by using multidisciplinary research (analysis of satellite images time series, detailed field inventory, simulated hydrological data), we focused on upstream propagation (i.e., incision consequent widening) an...
Bedload transport observed during a flood in May 2010 gave rise to several forms of accumulations small headwater basins located the Western Flysch Carpathian Mountains, Czech Republic.We have investigated critical conditions incipient motion largest boulders deposited c.Q 100 event (flood competence method).We tested formulas designed for high gradient streams two local mid-mountain relief.The results show that such magnitude is able almost all surface bed material and bedload steep (A ≤ 1...
This paper presents an analysis of both the contemporary and historic development geomorphic regime Ostravice River channel in Czech part Outer Western Carpathians. The assessment concentrates on conditions causes last 200 years compared with state European channels. original anabranching river pattern has gradually been replaced by a single narrowed channel. At some sections, riverbed lowered as much 2.5 m second half 20th century. These changes were due to strong anthropogenic impacts form...
Abstract Riparian vegetation reflects the current conditions and dynamics of streams. The floodplain along watercourse Morávka River was subject to study in this project. In some reaches, river has natural character an anabranching gravel-bed stream; contrast, other R. reaches are incised into bedrock. These cases were used assess potential changes as evidence negative processes taking place streams Beskydy Mts. results demonstrate a higher biodiversity channel. channel shows low values....
