Validation of a simplified AQUATOX model to assess quality status of a model river in Sardinia

In the framework of periodic update Sardinian River Basin Management and Water Protection Plans (Italian Law 152/2006, transposition 2000/60/EC Directive), we investigated AQUATOX model feasibility as a tool for assessing relationships between Driving forces, Pressures, States, Impacts Responses (DPSIR scheme). To do this, applied to forecast response (Italy) river quality status set different environmental perturbations, including nutrient load water flow variations. The final aim this work is study feasible model, based on DPSIR scheme, identifying necessary sustainable measures tackle criticalities resulting from known perturbations rivers.
