The global sediment cycle is a fundamental feature of the Earth system, balancing
competing factors such as orogeny, physical–chemical erosion and human action. In this …

Coastal wetlands, such as saltmarshes and mangroves that fringe transitional waters,
deliver important ecosystem services that support human development. Coastal wetlands …

Deltas are subaerial landforms that cap underlying deposits with subaqueous extensions
that result from a river feeding sediment directly into a standing body of water at a rate that …

River dams provide many benefits, including flood control. However, due to constantly
evolving channel morphology, downstream conveyance of floodwaters following dam …

Hydropower, although an attractive renewable energy source, can alter the flux of water,
sediments, and biota, producing detrimental impacts in downstream regions. The Mekong …

Large reservoirs can considerably alter the water-sediment dynamics and morphology of
alluvial rivers. Here we review the effects of two mega reservoirs operated with different …

River hydrology and geomorphology are largely influenced by human activities. The
operation of the Three Gorges Dam (TGD), which is the largest global hydropower project …

Morphological evolution of river deltas depends to a large extent on river discharges, which
are usually highly unsteady due to natural hydrological cycles and anthropogenic …

Over the past 60 years, because of the combined impacts of human activities and climate
change, the sediment load of the nine major rivers (the Yellow, Yangtze, Pearl …

River deltas offer numerous ecosystem services and host an estimated global population of
350 million to more than 500 million inhabitants in over 100 countries. To maintain their …
