Title: Discussion of "Reservoir Level Rise under Extreme Driftwood Blockage at Ogee Crest" by Loïc Bénet, Giovanni De Cesare, and Michael Pfister.

Subjects: Arch dams, Concrete dams, Wood density, Discharge coefficient
Abstract: Specifically, for a relative pier overhang HT p/HR=0.35 ht , the driftwood blockage resulted in HT =0.77 ht . In addition, the results for the Ova Spin crest (black triangles) show no significant discharge reduction up to HT p/HR=0 ht and do not follow the ogee crest data set. The resulting head HT H ht was measured after every sequence of added model logs. [Extracted from the article]
