Influence des endiguements et remblais sur l'inondation de la plaine de l'Agly
The influence of dikes and embankments on the Agly plain floods
Building of dikes along downstream reach of Agly River has protected the low plain from the more frequent floods, which encourages the economic development. In order to estimate the hazard linked with flooding and to decide relatively to urbanism documents, an hydraulic modelling was performed using 2-D software RUBAR 20. The boundary of the flooded areas was drawn for the 100-years' flood. However, the main features of flooding may change due to the division of the plain by many embankments that could slow or deviate the flow. Moreover, the always possible breaching of the main dikes constitutes the more damaging hazard for some areas.
