Protect a bridge’s abutments and define a gravel extraction that would not worsen scour or flood levels.
We modelled the river in 1D and 2D for the 100- and 150-year floods and compared both models. On that basis we designed rock-armour protection for the abutments and the extraction polygon. The file was submitted to the DOH with 27 drawing sheets.
