Seepage effects on bedload sediment transport rate by random waves

Estimation of Sediment Transport Rate of Karun River (Iran)

Several types of sediment transport equations have been developed for estimation of the river sediment materials during the past decades. The estimated sediment from these equations is very different, especially when they applied for a specific river. Therefore, choice of an equation for estimation of the river sediment load is not an easy task. In this study 10 important sediment transport equ...

Bedload and Suspended Sediment of a Watershed Impacted by Dams

Sediment transport relates to suspended sediment and bedload. The suspended sedi‐ ment plays the most important role on the land-ocen sediment flux. On the other hand, the bedload should be considered in order to assess the impacts of dams on sediment transport and sediment yield. Recent effects of dam construction have been widely reported. The sediment load has been reduced by more than 75% f...

Characterization of bedload intermittency near the threshold of motion using a Lagrangian sediment transport model

At the smallest scales of sediment transport in rivers, the coherent structures of the turbulent boundary layer constitute the fundamental mechanisms of bedload transport, locally increasing the instantaneous hydrodynamic forces acting on sediment particles, and mobilizing them downstream. Near the critical threshold for initiating sediment motion, the interactions of the particles with these u...

Interactions of Waves, Tidal Currents and Riverine Outflow and their Effects on Sediment Transport (RIVET II)

Studying the mixing of riverine freshwater and coastal water is the fundamental step to further understand the balance of a coastal/estuarine ecosystem (e.g., Hickey et al. 2010), seabed properties, sediment budgets (Gelfenbaum & Kaminsky 2010), and the sustainable management of the fluvial-estuary habitat (e.g., damming, dredging). The nearfield of a river plume represents an energetic environ...
