Ribeira da Asprela

The Ribeira da Asprela has been restored in sections with different natural-based solutions: at Outeiro (2009), natural engineering techniques stabilized the bed and banks; at Quinta das Lamas (2015), de-tubing promoted requalification and re-naturalization; and at Parque Central (2022), three retention basins for 10,000 m³ were created.
