We review the role of science in shaping river flood risk management policy in England, highlighting the relatively recent influence of fluvial geomorphology, river ecology, climate change and ecosystem services in evidence-based decision-making. The

Throughout British history rivers have been of profound economic, social and cultural importance – yet as we see with increasing frequency they have the potential to wreak great destruction. This book describes the natural and not-so-natural change

River Conservation and Management
A stratified random sample of 4 849 River Habitat Survey (RHS) sites was used to assess the physical character of rivers and streams in England and Wales in 2007-2008. Based on this sample, it is estimated that 11% of river length had a ‘near-natur

This paper describes how the attributes of a method for determining the physical quality of rivers are well-placed for use in environmental assessment and catchment planning in the U.K. The system, known as River Habitat Survey (RHS), uses a standard
