The terms river morphology and its synonym stream morphology are used to describe the shapes of river channels and how they change in shape and direction over time. The morphology of a river channel is a function of a number of processes and environmental conditions, including the composition and erodibility of the bed and banks (e.g., sand, clay, bedrock); erosion comes from the power and ...
River ecosystems are prime examples of lotic ecosystems. Lotic refers to flowing water, from the Latin lotus, meaning washed. Lotic waters range from springs only a few centimeters wide to major rivers kilometers in width. [5] Much of this article applies to lotic ecosystems in general, including related lotic systems such as streams and springs.
The many possible classifications of aquatic plants are based upon morphology. [5] One example has six groups as follows: [32] Amphiphytes: plants that are adapted to live either submerged or on land; Elodeids: stem plants that complete their entire lifecycle submerged, or with only their flowers above the waterline

The organisms that live around or in a river such as fish, aquatic plants, and insects have different roles, including processing organic matter and predation. Rivers have produced abundant resources for humans, including food , transportation , drinking water , and recreation.
A wide variety of river and stream channel types exist in limnology, the study of inland waters.All these can be divided into two groups by using the water-flow gradient as either low gradient channels for streams or rivers with less than two percent (2%) flow gradient, or high gradient channels for those with greater than a 2% gradient.
Nymphaeaceae has been investigated systematically for decades because botanists considered their floral morphology to represent one of the earliest groups of angiosperms. [6] Modern genetic analyses by the Angiosperm Phylogeny Group researchers has confirmed its basal position among flowering plants.
Thirdly, plant morphology studies plant structure at a range of scales. At the smallest scales are ultrastructure, the general structural features of cells visible only with the aid of an electron microscope, and cytology, the study of cells using optical microscopy. At this scale, plant morphology overlaps with plant anatomy as a
