Habitat modification

The habitat modification tab contains a representation of the Habitat Modification Score (HMS) and its components.  The HMS is a scoring system for engineering structures on watercourses.  Scores are allocated according to the extent of the structure and its life expectancy.

HMS scores are further classified into 5 classes to provide with a simple modification index from Semi-natural (blue) to Severely modified (red).  The total site score and index class are represented in the top 2 boxes.  In the graph below, the HMS component subscores are indicated. The graph below shows that the site is severely modified with a score of 2840.  The modifications accounting for most of this very high score are resectioning of the banks and bed and the presence of reinforcements.  Berms and embankments are also present but account for a much lower part of the total score.
