Multiscale flow-vegetation-sediment feedbacks in low-gradient landscapes

LG Larsen - Geomorphology, 2019 - Elsevier
Abstract Low-gradient fluvial landscapes (1–50 cm km− 1) occupy diverse settings (inland,
tidal, and deltaic wetlands, large-river floodplains, lowland streams) but share many …

How dynamic is the Brahmaputra? Understanding the process–form–vegetation interactions for hierarchies of energy dissipation

KK Nandi, C Pradhan, S Dutta, KK Khatua - Ecohydrology, 2022 - Wiley Online Library
The spatio‐temporal heterogeneity in process–form–vegetation interactions has enabled the

Prediction of bedload transport inside vegetation canopies with natural morphology

L He, Y Shan, C Liu, H Cao, X Liu, Y Guo - Journal of Hydrodynamics, 2024 - Springer
Due to vegetation drag and vegetation-generated turbulence, bedload transport in
vegetated channels is more complicated than that in nonvegetated channels. It is …
