Feasibility study for the improvement of flows on the hydraulic mesh of Corbie-Fouilloy The operation consists of carrying out a study of hydraulic modelling of the flows of the Somme on the Corbie – Fouilloy sector. This study should make it possible to assess the precise situation of the operation of the hydraulic mesh in this sector, to identify all the problems of management and variation of water levels encountered on the river network concerned and to propose solutions for improvements. The final objective is to improve, in the area concerned, the flow of many overflows and ultimately, to combat flooding in the Valley of the Somme. The resulting work will be the subject of subsequent applications for European aid.
