Decision Support System
The Decision Support System (DSS) is designed to assist decision-makers (including practitioners, land managers, and restoration planners) in identifying the most appropriate rehabilitation measures for urban and peri-urban streams. The tool operates through three sequential steps.
First, the user selects the indicators that best characterise the current condition of the stream under assessment. These indicators span multiple dimensions of stream health, including water chemistry, hydromorphology, and biological quality elements such as macroinvertebrate communities, diatoms, fish, and riparian vegetation.
Based on the selected indicators, the DSS identifies the most likely impairments, the underlying stressors and pressures driving the observed degradation, whether morphological, hydrological, chemical, or ecological in nature.
Finally, the system recommends a set of rehabilitation measures matched to those impairments.
