Abstract Following extensive flooding at Esch-sur-Sûre (Luxembourg) in 1993 and 1995, the Administration des Ponts et Chaussées appointed Lombardi Engineering Ltd (Switzerland) to carry out the prefeasibility and feasibility studies for a flood relief tunnel at Esch-sur-Sûre and a new spillway for the dam located on the River Sûre, 1.2 km upstream of the town. The 142 m long flood relief tunnel will cut a 900 m long meander of the River Sûre in order to protect the town from further damage due to floods, up to a maximum return period of 50 years. The construction of a new spillway on the left bank of the Esch-sur-Sûre dam with a discharge capacity of 400 m3/s will increase the dam safety in case of floods.
