Modelling water resources according to the Driver & Tasker model (1990) adapted for use in Portugal (LNEC, 2004)

The evaluation of possible impacts resulting from an increase in the concentration of pollutants originating from road traffic, both in the main discharge points foreseen in the project and in the waterways that receive them, is an important stage in the development of the water resources descriptor for Environmental Impact Studies. Modelling of the main pollutants, specifically Zinc (Zn), Copper (Cu) and Total Suspended Solids (TSS) is carried out using the Driver & Tasker model (1990) adapted for use in Portugal (LNEC, 2004).

As part of this project, BoG participated in the following studies:

• Environmental impact assessment of the implementation of the “EN2 – São Brás de Alportel and A22 Connection. Upgrade” road infrastructure project located in the district of Faro, covering the municipalities of São Brás de Alportel and Faro over a length of 7,718 metres.
• Environmental Impact Assessment of the implementation of the “Campo Maior Industrial Park Accessibility Improvement” project, a road infrastructure project located in the municipality of Campo Maior, covering the parishes of São João Baptista and Nossa Senhora da Expectação;
• Environmental impact assessment of the “EN211 – Bypass between Quintã and Mesquinhata” road infrastructure project located in the district of Porto, covering the municipalities of Marco de Canaveses and Baião over a 2,530-metres stretch of new road.
