Adgningsstrømmer

Adgningsstrømmer is a term used in some Nordic-language literatures to describe streams or flows that introduce new material, information, or energy into a system. The word is formed from a root related to adding or attaching and the Danish word strømmer for streams, and it is typically employed to discuss how inputs are delivered and subsequently integrated over time.

In conceptual use, adgningsstrømmer denotes not just the raw input but the dynamic process by which inputs move through a system, interact with existing components, and contribute to change. The concept emphasizes both the rate of input and the system’s capacity to assimilate or respond to what is added. Depending on the field, inputs can be physical (such as sediments, nutrients, or particulate matter), informational (such as data packets or ideas), or energetic (such as heat or electrical energy). The resulting system state is shaped by factors like flow velocity, turbulence, filtering or processing mechanisms, and storage or transfer pathways.

Fields of application include ecology and hydrology, where adgningsstrømmer can describe how streams transport and deposit materials that alter habitat structure; information science or data engineering, where they refer to data ingestion streams feeding processing pipelines; and social sciences, where the term can illustrate cumulative inputs of resources, knowledge, or influence into a networked system. Modelling often involves characterizing the input rate, the residence time of inputs, and the system’s response function.

Measurement approaches vary by domain, but common elements are rate (inputs per time), composition (types of inputs), and system response (changes in state variables). See also concepts like advection, accretion, and input–output modelling.
