Figure 6. Chord diagram relating sampling stations of non-perennial Mediterranean rivers between different types of SOM (cluster I, II and III), MATTM (ephemeral, episodic, intermittent and ephemeral), IPH (ephemeral, intermittent and temporal) and TRivers (episodic, intermittent-dry, intermittent-pools and perennial) classification. The width of the connection is based in the percentage of occurrence between of the categories of each classification.
