The RAT methodology has been modified by the NIEA to meet more practical application requirements and has been re-named as the River Hydromorphology Assessment Technique (RHAT); taking account of the River Habitat Survey (RHS) methodology developed by the UK Environment Agency. The RHAT methodology is a useful tool to assess the departure of hydromorphological features from ‘naturalness’ and allows for the assignment of a morphological classification directly related to WFD status.

For more information please see the ‘RHAT Surveys‘ section on our main website.
