As part of the implementation of the GEMAPI competence, CAPBP wishes to study the hydraulic operation of the Ouse des bois watershed in order to develop a flood risk reduction program. The objective will be to better characterise the flood hazard and the operation of rivers during flooding periods in order to propose flood prevention actions: development, restoration of flood expansion fields, maintenance of streams, awareness and communication. Finally, an optional tranche will allow the development of a hydrometeorological forecasting and alerting tool for local residents.
