Habitat modification

The habitat modification tab contains a representation of the average 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  structures and their 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 reach is significantly modified with an average score of 1112.  The modifications accounting for most of this very high score are resectioning of the banks and bed, the presence of weirs, bridges and reinforcements.
