Abstract

En 中文

• Water Quality Index indicates gradual deterioration along the Guadalquivir River. • The poorest water quality is found in the lower-middle reaches of the river. • Agricultural activities and impacted tributaries contribute to river deterioration. • Changes in biological indices signal undetected threats to the river. • Multidisciplinary analyses can identify potential targets for remediation actions.
