Abstract
Overview
ISO 19234:2024 - Hydrometry - Low cost baffles to aid fish passage on triangular profile gauging weirs specifies how to integrate on the downstream face of triangular‑profile gauging weirs. It applies to weirs operated in modular flow (critical depth) and covers both () and (). The first edition (2024) replaces the 2016 technical report and adds guidance for flat‑V weirs and spreadsheet design tools available from ISO.
