A stream consisting of a series of small pools or lakes connected by short stream segments; eg., a stream commonly found in a region of paternoster lakes or an area underlain by permafrost. Bedload: Sediment moving on or near the stream bed and frequently in contact with it. Bedload discharge: The quantity of bed load passing a given point in a unit of time, expressed as dry weight. Bed roughness: A measure of the irregularity of stream bed materials as they contribute to resistance to flow. Commonly measured in terms of ▇▇▇▇▇▇▇'▇ roughness coefficient. Benthos: Organisms living on or within a stream's substrate. Berm: A levee, shelf, ledge or bench along a stream bank that may extend laterally into the channel to partially obstruct the flow, or parallel to the flow to contain the flow within its stream banks.
