ASTM WK67310

New Test Method for Scour of Hydrodynamic Separators and Settling Devices

1. Scope

The promotion of knowledge of the family of technologies known internationally as stormwater control measures (SCMs), including stimulation of research and the development of test methods, specifications, practices, guides, and nomenclature. SCMs provide for stormwater quality treatment, volume control, flow management, and runoff detention, retention, and capture and use.

This activity shall support and serve as a resource for other ASTM committees in their activities that include stormwater control measure issues. This support may include dissemination of specific requests for standards throughout ASTM's existing committee base, as well as the maintenance of appropriate liaison relationships (internal and external) related to this subject area. The committee will not duplicate the efforts of existing ASTM technical committees. The work of this committee will be coordinated with other ASTM committees and other organizations having mutual interest.
