Morphology is a branch of geomorphology that deals with the forms of natural water bodies such as rivers, lakes, estuaries, lagoons, coastal zones and seas, as well as with the processes that create and modify these forms. These processes are the erosion, transport and deposition of sediment (cobbles, gravel, sand, silt, clay). In its operational meaning, morphology includes not only planform and bed topography but also bed sediment composition. Morphological behaviour is the manifestation of the changes in planform, bed topography and bed sediment composition.
Practically all rivers are subject to morphological processes.
