The Geomorphic Unit survey and classification System (GUS)

The present work is a 2016 revised version of the former one published in 2015 (namely MLG 122/2015) and illustrates a system for the classification and survey of geomorphic units, named GUS.

This method is used to identify, characterize and analyse the assemblage of geomorphic units  within a given reach. The  GUS is contextualized within a broader system for the  hydromorphological assessment, analysis and monitoring of  water courses (IDRAIM) and is suitable  for integrating the  MQI(Morphology Quality Index) at the reach scale. It is also aimed at allowing the establishment of links between hydromorphological conditions at reach scale, characteristic geomorphic units and related biological conditions.
