What is a characteristic of coastal plain stream origins?

The characteristic of coastal plain stream origins is typified by a gradual transition, low relief, and sandy beds. Coastal plain streams emerge in areas where the topography is relatively flat and gently sloping, which leads to these streams having a slow and meandering flow. The sandy beds are indicative of the types of sediments typically found in these regions, as they are often deposited by water over extended periods. This environment fosters low-energy conditions that allow for the accumulation of finer sediments like sand, contributing to the overall formation and behavior of these streams. In contrast, other characteristics mentioned, such as high velocity or well-defined transitions, are more representative of mountain streams or rugged terrains, which are not found in coastal plain settings.
