RESTORATION CHALLENGES FOR URBAN RIVERS

• Key-note presentation for International Water
  Association specialist conference on diffuse
  pollution, Johannesburg, 9-12 August 2005.
• BJ DArcy, T Rosenqvist, G Mitchell, R Kellagher
  and S Billett
• INTRODUCTION
• BMP techniques have been widely deployed to
  minimise pollution in runoff from urban areas
  practical experience in Sweden and parts of the
  USA goes back decades (see Campbell et al 2004).
  But how effective have they been in practice at
  preventing deteriorations in quality as
  catchments urbanise? And can the technology be
  successfully retrofitted to restore degraded
  urban watercourses?
