What term describes the gradual transition from wetlands to streams?

The term that describes the gradual transition from wetlands to streams is best captured by geomorphology, which is the scientific study of landforms and the processes that shape them. Geomorphological processes include the evolution of landscapes, which encompasses how wetlands give way to flowing water bodies like streams. This transition highlights the interactions between hydrology (the movement and distribution of water) and landform development, making geomorphology the most relevant concept in this context.

Other terms provided refer to specific geographical regions or features rather than the process of transition itself. Coastal plain stream origins pertain specifically to streams that form in coastal plain environments. Piedmont and mountain stream origins discuss streams that arise in different topographies, specifically the rolling hills of the Piedmont and the steep terrains of mountainous areas. None of these capture the broader concept of transitions from wetlands to streams as effectively as geomorphology does.
