Bank erosion and large wood recruitment along a gravel bed river

The Gravel-Bed River Reach Properties Estimation in Bank Slope Modelling

Dynamic transport capacity in gravel-bed river systems

Sediment transport capacity mediates the transfer and storage of bed material between alluvial reservoirs in a drainage system. At intermediate time scales (100-102 yr) corresponding to the evolution of sediment pulses, conditions governing bed-material transport capacity under the hydrologic regime respond to variations in storage and sediment flux as pulses extend, overlap, and attenuate thro...

Do gravel bed river size distributions record channel network structure?

[1] Bed load sediment particles supplied to channels by hillslopes are reduced in size by abrasion during downstream transport. The branching structure of the channel network creates a distribution of downstream travel distances to a given reach of river and thus may strongly influence the grain size distribution of the long-term bed load flux through that reach. Here we investigate this hypoth...

Experimental Investigation of Groin Placement On Minimizing River Bank Erosion

River banks are exposed to bank erosion and destruction. One of the river engineering goals is to provide human life requirements and reduce river danger. So spreading extent of this phenomenon, whose risk and other important factors must be recognized. Using groins is one of the control ways that by accurate design and accurate performance, bank erosion control and field reclamation would be p...

Evaluating fine sediment mobilization and storage in a gravel-bed river using controlled reservoir releases

Two controlled flow events were generated by releasing water from a reservoir into the Olewiger Bach, located near Trier, Germany. This controlled release of near bank-full flows allowed an investigation of the fine sediment (<63 μm) mobilized from channel storage. Both a winter (November) and a summer (June) release event were generated, each having very different antecedent flow conditions. T...
