Abstract Vegetation present in the water streams, on banks and floodplain areas largely affects river hydraulics. Indeed, vegetation significantly influences hydrodynamics, sediment transport, bedforms, pollutant transport. Environmental management of rivers requires an understanding various processes predictive capabilities models. In past, many studies were conducted, especially laboratory se...

Differential pressure transducers can be used to monitor the suspended-sediment concentration in a water column. Suspended sediments with densities greater than water increase the fluid density, which is determined by measuring the fluid pressure change between two depths. Lewis and Rasmussen (1999) used a densimetric technique under controlled conditions to determine suspended-sediment concent...

Mixed sediment beaches are morphologically distinct from and more complex than either sand or gravel only beaches. Three digital imaging techniques are employed to quantify surficial grain size and bedload sediment transport rates along the mixed sediment beaches of Kachemak Bay, Alaska. Applying digital imaging procedures originally developed for quickly and efficiently quantifying grain sizes...

In this paper we study the numerical approximation of bedload sediment transport due to shallow layer flows. The hydrodynamical component is modeled by a 2D shallow water system and the morphodynamical component by a solid transport discharge formula that depends on the hydrodynamical variables. The coupled system can be written as a nonconservative hyperbolic system. To discretize it, first we...

In mountain rivers, long-term observations of water and sediment fluxes are crucial for understanding the dynamics bedload fluctuations. We analyze 7 years continuous data gathered from eight geophone plates at a monitoring station in glacier-fed Sulden/Solda River (South Tyrol, Italy) to estimate flux 1-min scale. Sixty-five samples were used derive calibration equations adopted quantify trans...

A long wave run-up model is applied to calculations of wave-induced flow velocities, sediment transport rates and bottom changes in a swash zone. First, properties of the water tongue motion and resulting lithodynamic response are analysed theoretically. Next, an attempt is made to run the model for the natural conditions encountered on the south Baltic Sea coast. The Lagrangian wave-induced ve...
