REVIVAL OF DISAPPEARING LANDSCAPES IN RIA DE AVEIRO, PORTUGAL
Wageningen Universiteit en Researchcentrum
LANDSCAPE DESIGN

Ria de Aveiro is a unique estuarine lagoon located on the Northern coast of Portugal. This research by design study aims to investigate the relationship between the landscape and the dynamics of the lagoon to reduce the impact and risk of flooding in the planning area as a whole. The research has been worked up in a design that protects the area against flooding at least until 2100 and improves the quality of the landscape.
Ria de Aveiro is the most extensive lagoon system in Portugal and one of the most dynamic in terms of physical and biogeochemical processes. Divided from the Atlantic Ocean by a sand bar, the lagoon presents an extremely varied landscape largely due to the intense influence of tidal movements. Its unique character has made Ria de Aveiro one of the most remarkable ecosystems in Europe, not only in size but also in biodiversity. The unusual and powerful marine influence in the lagoon supports the development and consolidation of a multitude of biotopes of great ecological importance. This last-named aspect is particularly due to the variety in the water salinity patterns and gradients found in the lagoon. In recent years, the landscape dynamics in the lagoon have intensified, so that there is an ever greater risk of flooding in agricultural areas, nature areas and even in the old centre of Aveiro.
First, the project presents an analysis of the landscape and its characteristics, arranged in landscape units. This gives an understanding of the landscape dynamics and how the different landscapes interact with each other.
Next, the flood risk for 2100 has been assessed using a hydrodynamic model developed by NMEC Lab in Aveiro. The results have been applied to the landscape units to understand how the different areas in the lagoon would be affected. Three different approaches have been analysed with the aid of the hydrodynamic model to assess their effectiveness with regard to the 2100 flood risk. From these options, one has been chosen that ensures protection while providing opportunities for improving the quality of the landscape. The revival of the disappearing landscapes of the lagoon is then presented in a design whose aim is to explore and exploit the multitude of possibilities that this unique landscape has to offer.
