Table 6.

Classification table for the beta SDAM AW. Blank entries in a column mean that the state of a certain indicator does not change the outcome. For example, if a reach has no hydrophytes, few aquatic invertebrates, and EPT taxa are present, it will be classified as At least intermittent, regardless of whether algae or fish are observed.
