pathway along the entire length of a stream. A
gradient of physical, chemical, and biological
processes occur from source to mouth.

water and sediment downstream and movement of fish
upstream and downstream is only the most obvious
example of the loss of longitudinal
The concept also applies to the cycling of
nutrients, continuum of habitats, influx of organic
materials, and dissipation of energy.
