Abstract

The city of Lisbon is situated near the estuary of the river Tejo. The estuary separates the urban region west of the estuary from a more rural area in the eastern part. A new bridge will be built over the estuary modifying the traffic patterns of the region. As the city of Lisbon is built in a very complex region, the wind flow and the dispersion of pollutants are influenced by phenomena belonging to different mesoscale subscales. In view of the different scale influences, a nested grid technique is applied to simulate the wind flow and the dispersion
