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.
What can mapped drainage systems on Mars teach scientists about the red planet's watery past? This is what a recent study published in the Proceedings of the National Academy of Sciences hopes to address as a team of scientists ...

Billions of years ago, it rained on Mars. The water collected in valleys and rivers, filled and spilled over the rims of craters, and was funneled into canyons, perhaps even making its way to a large Martian ocean.

Billions of years ago, water flowed across Mars. Most scientists agree the red planet had rivers. But did those rivers flow into an ocean? New research from the University of Arkansas found strong evidence in Mars' geology ...

Rivers are Earth's arteries. Water, sediment and nutrients self-organize into diverse, dynamic channels as they journey from the mountains to the sea. Some rivers carve out a single pathway, while others divide into multiple ...
