Description

The wetland of Ebro Delta tends to loose the half of its land. The River Ebro discharges less than 1% of what the river used to discharge at the beginning of the 20th century. The dams, the fall in precipitation in its drainage basin and the excess use of water for irrigation cause the decrease of sediments transported to the area, resulting in the recession of certain sections of the delta. The reduction in flow encourages the intrusion of salt water that penetrates the river underneath the fresh water and reduces its depth, affecting important ecosystems that exist in the area. The proposed structure aims to direct different types of sediments through different angles and degrees of porosity, creating various ecosystems in time, which can evolve in emerged environments through the re-configuration of the landscape. Catalogues of porosity applied in cell configurations and various cell surfaces, using the voronoi tool, are used to define the protocol of differentiation and variation depending on the size of sediment and the desired degree of perforation in each area of the site.
