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.
Earthquakes don't just shake the ground, they can also shift rivers, damage stop banks and raise the risk of flooding for years afterward.

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 ...

Dry river channels and lake beds on Mars point to the long-ago presence of a liquid on the planet's surface, and the minerals observed from orbit and from landers seem to many to prove that the liquid was ordinary water.
