TS 12081

TS 12081 is a terminology standard that brings together definitions of terms related to running waters as a receiving environment. Standards of this kind help different disciplines use the same concepts in the same way, which is especially important in hydrology, aquatic ecology, environmental management, and water-resources practice where terms such as river, channel, flow, and regime need consistent meaning.

Why running-water terminology matters

Running waters are central to the natural movement of surface water and are closely linked to water quality, habitat structure, sediment transport, flood behaviour, and basin-scale management. In general technical use, a terminology standard does not prescribe measurements or performance requirements; it establishes the conceptual vocabulary that supports clearer reporting, research, planning, and inter-agency communication.

What this standard covers

The scope of this standard is the definitions of terms related to running waters. In practical terms, it helps clarify the naming used for river systems, flow-related features, and the environmental concepts associated with them. That makes it easier to interpret technical documents consistently across environmental studies, water management work, and ecological assessments.

• The document’s main subject is terminology for running waters.
• Its role is to define concepts, not to set a test method or numerical limit.
• Placement in the environmental protection group reflects its connection to aquatic and natural systems.
• Terminology standards reduce ambiguity in technical communication.
