ASTM D5614

ASTM D5614 is the ASTM standard for measuring open channel flow of water with broad-crested weirs. It provides a technical framework for determining flow in channels where a broad-crested weir is used as the measuring structure, helping support consistent and defensible water measurements. For engineers, operators, and laboratories, this standard matters because it can improve comparability, reduce uncertainty, and support reliable hydraulic assessment in practical field and compliance work.

Overview of ASTM D5614

The official title, Standard Test Method for Open Channel Flow Measurement of Water with Broad-Crested Weirs, indicates a method centered on flow measurement in open channels using a specific weir type. ASTM D5614 is intended to guide how water flow is measured with broad-crested weirs so results can be used more consistently across applications. As an ASTM standard, it serves as a technical reference for measurement practice, helping users align procedures, equipment use, and reported results with an established method.

Common use cases of ASTM D5614

This standard is commonly relevant wherever water flow in an open channel must be measured with a broad-crested weir. That may include monitoring channels, test setups, and other hydraulic measurement installations where a weir-based method is appropriate. ASTM D5614 is useful when selecting or evaluating a measuring arrangement, documenting flow readings, or comparing results across sites and operating conditions. It is especially helpful when a repeatable, standardized approach to flow measurement is needed.

Benefits of using ASTM D5614

Using ASTM D5614 can support more consistent flow measurement practices and stronger technical confidence in reported values. It helps organizations work from a recognized standard, which may aid compliance efforts, internal quality control, procurement decisions, and performance verification. For open channel applications, a standardized method can reduce ambiguity in measurement setup and interpretation. ASTM D5614 also supports clearer communication between parties who need a common reference for evaluating water flow with broad-crested weirs.
