In the context of phenomena, fluvial refers to processes and dynamics associated with the action of running water in rivers and streams, including erosion, sediment transport, and deposition. Fluvial phenomena encompass the entrainment and downstream movement of clastic material, channel incision and lateral migration, bar formation, overbank flooding, and the development of alluvial plains and terraces. These processes are governed by hydraulic variables such as discharge, flow velocity, shear stress, and sediment load, and they operate across a range of spatial and temporal scales, fundamentally shaping drainage networks and continental surface morphology.
In 2024 alone, flood-related disasters around the world caused more than 8,700 deaths and economic losses exceeding 450 billion euros, with cumulative global losses of about 2.7 trillion euros over the previous decade. Against ...

Venus may be overwhelmingly inhospitable today, but many planetary scientists believe that it wasn't always this way. Billions of years ago, some observational evidence suggested that our planetary neighbor may have looked ...
The Euphrates River is the longest river in Western Asia and runs through the eastern side of the Fertile Crescent. Flowing over 1,700 miles from Turkey through Syria and Iraq, the river played a crucial role in sustaining ...
This month, ESA's Mars Express takes us to Shalbatana Vallis: a fascinating Martian valley surrounded by signs of water, lava, craters and chaos. Shalbatana Vallis is an impressive channel near Mars's equator. This image, ...

Rivers are rarely the calm, orderly streams we imagine on maps. Over time, their winding paths—called meanders—shift, bend, and occasionally snap off in sudden "cutoff" events that shorten loops and reshape the landscape. ...
