Rehabilitation and regulating of the Ribeira of Santa Luzia – construction of weirs A1 to A4 and the Tornos bridge

Works to be carried out further to the storms on February 20th 2010. The object of this works contract is the implementation of 4 weirs on a stretch of Ribeira de Santa Luzia, with a steep slope.
The weirs, transversal interception and retention structures (temporary) for solid material ensure the passage of the runoff of liquids and smaller solids, whilst the blocks with most potential for destruction are retained. In this way materials with large dimensions are prevented from being ‘dragged’ to downtown Funchal, reducing the flow capacity of the stream and contributing to a greater incidence of flooding.
