Traditional policies for managing river bank erosion are currently being reconsidered as a result of increased awareness regarding
the unsustainable nature of some forms of bank protection, and the role played by bank erosion in providing ecosystem
services and supporting geomorphological functions. River managers are therefore increasingly seeking to preserve bank erosion
within a defined erodible corridor. This paper provides an overview of the erodible corridor concept, focusing on the
provision of guidelines for applying the concept in practice.We argue that a nested approach is required to address management
objectives across a range of scales (network scale, reach scale, local scale) and review the different geomorphic tools that are
available to help managers define the extent and inner sensitivity of the erodible corridor. These tools include simple rules of
thumb such as evaluation of the equilibrium meander amplitude, historical approaches based on overlays of historical channel
position, and simulation modelling. The advantages and limitations of each of these tools are discussed.
