DOI: 10.1002/esp.4195
Abstract: Sediment often enters rivers in the form of sediment pulses associated with landslides and debris flows. This is particularly so in gravel-bed rivers in earthquake-prone mountain regions, such as Southwest China. Under such circumstances, sediment… read more here.

DOI: 10.1002/esp.4606
Abstract: Suspended load transport can strongly impact ecosystems, dam filling and water resources. However, contrary to bedload, the use of physically based predicting equations is very challenging because of the complexity of interactions between suspended load… read more here.

DOI: 10.1016/j.jsames.2020.102522
Abstract: Abstract Gravel-bed rivers exhibit remarkable dynamics and distinctive morphological patterns which influence the biological processes, as well as the river ecosystem resilience to human impacts. Classifications of river ecosystems into groups with morphologically distinct patterns… read more here.
