Case Studies

UK Projects Map > Case Studies

The RRC has compiled a list of best practice case studies from the many site visits that its staff have been on over the years. The case studies give an overview of each project with key information such as dates, location, cost, design and the RRC's view on its subsequent performance. 

The case studies can be sorted by project name, river name and year of completion by clicking on each heading.
