Improvement of the hydraulic situation of the Pisbaach

Hydrology

A new PAP construction project has been planned in Pissange, near the Pisbaach stream. The developer, Immo Brameschhof, has volunteered to also promote the renaturation of the Pisbaach.

The feasibility study was carried out by the municipality of Reckange-sur-Mess. As part of this, a hydraulic simulation was carried out for the planned new course of the stream. The aim of these simulations is to reduce the likelihood of flooding from the stream in the future.

Key features

• Proximity to existing buildings and trees
• Consideration of the natural typology and reference situation for the stream
• Length of the renaturalised stream: 600 km
• Characteristic flow: MNQ, MQ, HQ100
• 1D hydraulic model
• Planting and maintenance plans

Our missions

• Topographical survey
• In-situ ichthyological and ecological analyses
• Flow simulations and creation of a longitudinal profile of the riverbed and several cross-sectional profiles with visualisation of flood accumulation
