Impact of river construction projects on the groundwater balance: A case study of a river widening project in the Alpine Rhine valley

When planning river construction projects, it is essential to consider their impact on the groundwater balance. Numerical groundwater modelling can significantly improve our understanding of the river-aquifer system, as demonstrated by the modelling conducted for the preliminary study of the Rhine widening in Schaan, Buchs and Eschen (Switzerland/Liechtenstein).
