Plants should become more abundant at edges of the river with increasing river size, especially in lowland rivers where finer sediments have been deposited and facilitate rooting. The main channels likely have too much current and turbidity and a lack of substrate to support plants or periphyton.
Those living in rivers do, however, need sufficient structural xylem to avoid being damaged by fast flowing water and they also need strong mechanisms of attachment to avoid being uprooted by river flow. Many fully submerged plants have finely dissected leaves, probably to reduce drag in rivers and to provide a much increased surface area for ...
This stream operating together with its environment can be thought of as forming a river ecosystem. River ecosystems are flowing waters that drain the landscape, and include the biotic (living) interactions amongst plants, animals and micro-organisms, as well as abiotic (nonliving) physical and chemical interactions of its many parts.

The word riparian is derived from Latin ripa, meaning "river bank". [3] Riparian is also the proper nomenclature for one of the terrestrial biomes of the Earth. [4] Plant habitats and communities along the river margins and banks are called riparian vegetation, characterized by hydrophilic plants. [5]

A wetland is a land area that is saturated with water, either permanently or seasonally, such that it takes on the characteristics of a distinct ecosystem.The primary factor that distinguishes wetlands from other land forms or water bodies is the characteristic vegetation of aquatic plants, adapted to the unique hydric soil.
Arundo is a highly invasive plant in southwestern North American rivers, and its promotion as a biofuel in other regions is of great concern to environmental scientists and land managers. [22] Arundo donax was introduced from the Mediterranean to California in the 1820s for roofing material and erosion control in drainage canals in the Los ...
