Rivers exchange water, materials, energy, and nutrients, in a reciprocal manner with the surrounding environment. River water quality, sediment characteristics, and biological communities, all reflect characteristics of the upstream, and even the downstream environment.aintaining position in the face of flow can be energetically costly, but provides access to a conveyer belt-like food-delivery system.
