| Popis: | The French torrent control service designed and has been maintaining, directly or indirectly by technical support, more than three hundred open check dams. These structures provide key protection services against torrential floods and debris flows. Some structures are several decades old and yet experienced several events of high magnitude. Until recently, design criteria were lacking, and these structures were designed empirically by intuition and trial and error. A detailed inventory was performed in 2017-2018 to gain knowledge on past experience and lessons learnt from these structures. This chapter recall basic knowledge on open check dam design, gives an overview of the existing structures in France and show statistics of the most frequent malfunctions and adaptations that were required. Three sites are described more in detail to exemplify typical situations where adapting management was performed. We hope sharing these lessons learnt based on past errors will prevent their repetition elsewhere. |
