The rise of the mean sea level and the increase of the intensity and frequency of the precipitation extremes are presently raising the flood risk of these territories, jeopardizing their maintenance and future development. The present work focuses on how these climate change processes can raise the risk of the urban drainage flooding events at the cities waterfronts. The relevance of the problem is reinforced by the present incapacity of the urban drainage systems to follow the needed adaptation, forcing the delta and estuary cities to rethink the management of their storm water outflow. Under this view, the main drainage adaptation strategies and measures are analysed, namely in urban planning and design, and on the benefits of the integration of natural processes. To contextualize the addressed problem, the possible drainage flood impacts over the Lisbon riverfront are analysed. The influence of the climate change processes over the current drainage system and the flood risk of this area are shown, demonstrating the need for integration of the drainage problem in the future urban planning.
