Fluvial geomorphology is the scientific study of the landforms created and modified by flowing water. It investigates the dynamic processes of erosion, sediment transport, and deposition by rivers and streams, which collectively shape features such as channels, floodplains, terraces, and deltas. By analyzing the complex interplay between water discharge, sediment load, and the underlying geology, this field explains how river systems sculpt terrestrial landscapes and respond to changes in climate, tectonics, and human activity.
