River weirs – Design, maintenance, modification and removal (C763)

This guide is the result of CIRIA Research Project (RP1009). The work was produced, under contract to CIRIA, by JBA Consulting, Mott MacDonald and FAS Heritage with the River Restoration Centre appointed as a special advisor. It replaces the EA guide River weirs – good practice guide (Richard et al 2003). The new guide provides good practice guidance on the design, maintenance, modification and removal of river weirs, including weirs on canalised rivers, canal by-weirs and side weirs, and river barrages. It does not cover dams, reservoir spillways, estuarine barrages or structures regulating natural lakes.

The document will have a broad readership given the wide range of stakeholders involved in the operation of weirs and the use of rivers. The structure of the document reflects this. Readers will come to the guide with different perspectives, depending on the drivers for change and the questions they are trying to answer (see below). The guide  aims to direct readers towards the information that they are looking for, and to alert them to other issues that they may not be aware of.  

As part of the project, CIRIA and the Steering Group will be seeking feedback on the guide from users.
