Following the floods of July 2021, Sweco contributed to the redevelopment of severely affected Walloon municipalities, including Verviers, Trooz and Li\u00e8ge. Commissioned by the Walloon Public Service, we supported these municipalities with hydrological and urban planning studies aimed at strengthening water resilience and long-term adaptability.<\/p>\n

In Li\u00e8ge, this work resulted in an implementation-ready masterplan for the area stretching from the Ourthe canal to its confluence with the Vesdre, bringing together water management<\/a>, landscape integration and spatial development<\/a>.<\/p>\n<\/p>\n\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\n \t\t<\/div>\n\t<\/div>\n<\/section>\n\n\n

A masterplan for the confluence of the Vesdre and Ourthe<\/h2>\n

In September 2023, a second series of studies began, with Sweco supporting the City of Li\u00e8ge through two separate assignments: a hydrological assessment and technical solutions for three critical locations in Bressoux, and an implementation-ready masterplan for the banks of the Ourthe canal through to its confluence with the Vesdre.<\/p>\n

The central question was: how can the area be made more water-resilient while preserving its existing spatial and functional dynamics?<\/p>\n\t\t<\/div>\n\t<\/div>\n<\/div>\n<\/section>\n\n\n

For the masterplan, our team analysed flood risks, with particular attention to the Angleur district and previous studies carried out for the site. Based on this analysis, we developed two scenarios exploring different principles for resilient development. The assessment of these scenarios led to a preferred option, which now forms the basis for the area\u2019s further development.<\/p>\n
