Bedload transport: a walk between randomness and determinism. Part 2. Challenges and prospects

C Ancey - Journal of Hydraulic Research, 2020 - Taylor & Francis
By the late nineteenth century, the scientific study of bedload transport had emerged as an
offshoot of hydraulics and geomorphology. Since then, computing bedload transport rates …

Morphodynamic modeling of river-dominated deltas: a review and future perspectives

D Edmonds, AJ Chadwick, MP Lamb… - Authorea …, 2022 - techrxiv.org
River deltas are a compelling target for numerical simulation because they contain
seemingly organized patterns and shapes at a variety of scales. For instance, most river …

Stability and asymmetry of tide‐influenced river bifurcations

AP Iwantoro, M van der Vegt… - Journal of Geophysical …, 2022 - Wiley Online Library
Bifurcations are important geomorphological features in tide‐influenced deltas. At
bifurcations, river flow and tides distribute sediment over the channel network and determine …

Defining the length parameter in river bifurcation models: a theoretical approach

M Redolfi - Earth Surface Processes and Landforms, 2023 - Wiley Online Library
One‐dimensional models for river bifurcations rely on a nodal point relation that determines
the distribution of sediments between the downstream branches. The most widely‐adopted …

Free alternate bars in rivers: Key physical mechanisms and simple formation criterion

M Redolfi - Water Resources Research, 2021 - Wiley Online Library
Free alternate bars are large‐scale, downstream‐migrating bedforms characterized by an
alternating sequence of three‐dimensional depositional fronts and scour holes that …

Free and forced morphodynamics of river bifurcations

M Redolfi, G Zolezzi, M Tubino - Earth Surface Processes and …, 2019 - Wiley Online Library
Water and sediment distribution by river bifurcations is often highly unbalanced. This may
result from a variety of factors, such as migration of bars, channel curvature and backwater …

Modeling of scour depth and length of a diversion channel flow system with soft computing techniques

NK Alomari, P Sihag, AM Sami Al-Janabi, B Yusuf - Water Supply, 2023 - iwaponline.com
This study employed soft computing techniques, namely, support vector machine (SVM) and
Gaussian process regression (GPR) techniques, to predict the properties of a scour hole …

Flow and suspended sediment division at two highly asymmetric bifurcations in a river delta: Implications for channel stability

K Kästner, AJF Hoitink - Journal of Geophysical Research …, 2019 - Wiley Online Library
The division of sediment at river bifurcations results from the complex interaction between
three‐dimensional flow, planform, and channel bed morphology, as well as the …

Viewing second-order phase transitions as a metaphor for river bifurcations

N Ragno - Journal of Fluid Mechanics, 2023 - cambridge.org
The Earth's landscape hosts a variety of patterns resulting from the interaction between a
sediment-carrying fluid and an erodible boundary. Here, the morphodynamics of river …

Coupled morphodynamics of river bifurcations and confluences

N Ragno, M Redolfi, M Tubino - Water Resources Research, 2021 - Wiley Online Library
Multithread fluvial environments like anastomosing and braided rivers are fundamentally
directed by the continuous concatenation of channel bifurcations and confluences, which …
