Short summary
The presented study mainly describes the loading on a flexible barrier at rest in order that the static component of the force exerted by the dead zone received limited attention up to now. Four interaction modes are identified from a gentle flow stopping to high granular jump and/or overtopping. Interestingly, overflow resulted in a significant increase in the residual load and were almost twice that observed in the absence of overflow.
