River bed sediments typically fine downstream, where fining of median grain sizes are often
described as exponential, except where fine gravel abruptly transitions to sand. Across the …

At a global scale, delta morphologies are subject to rapid change as a result of direct and
indirect effects of human activity. This jeopardizes the ecosystem services of deltas …

Water and sediment supply are essential to the health of deltaic ecosystems. Diverse
datasets were integrated to better understand how climate change is shifting the supply of …

Abstract The protection of Lake Baikal and the planning of water management measures in
the Selenga River Basin require a comprehensive understanding of the current state and …

Riverbeds often fine downstream, with a gravel‐bedded reach, a relatively abrupt gravel‐
sand transition (GST), and a sand‐bedded reach. Underlying this behavior, bed grain size …

This study presents detailed suspended sediment budget for the four Siberian river deltas,
representing contrasting conditions between Northern and Southern environments. Two of …

As large, deep rivers enter their coastal reaches, they are usually affected by a lengthy
backwater zone. Recent studies have demonstrated pronounced geomorphic effects, such …

Channel bifurcations control the distribution of water and sediment in deltas, and the routing
of these materials facilitates land building in coastal regions. Yet few practical methods exist …

The grain size 2 mm is the conventional border between sand and gravel. This size is used
extensively, and generally without much physical justification, to discriminate between such …

Downstream fining of bed sediment in alluvial rivers is usually gradual, but often an abrupt
decrease in characteristic grain size occurs from about 10 to 1 mm, ie, a gravel‐sand …
