Details

CIRIA has published good practice guidance on the design, maintenance, modification and removal of weirs. The new guide replaces the Environment Agency’s ‘River weirs: Good practice guide’ published in 2003.

The guide covers weirs on rivers, canals and canalised rivers, including river barrages. It does not cover dams, reservoir spillways, estuarine barrages or structures regulating natural lakes. The guide covers both the removal of weirs or, if they are serving an essential function, how to manage and/or modify them to minimise negative impacts.

The guide is aimed at all those involved in the planning, design, construction, maintenance, modification or removal of weirs on rivers, canals and canalised rivers.
