stream channel evolution

Stream channel evolution refers to the natural changes a river or stream undergoes over time. This includes adjustments in its shape, path, and size due to processes like erosion (wearing away land), sediment deposition (building up land with silt and sand), and flow dynamics. These changes are influenced by factors such as weather, land use, and sediment supply. Over time, channels can migrate, split, or become wider or narrower, shaping the landscape and impacting ecosystems. Understanding this evolution helps manage water resources, prevent flooding, and preserve natural environments.
