Description
The combination on the same dam of Piano Key weir (PK-Weir) and fusible structures offers a highly effective passive solution for managing flood discharges. This concept first introduced by Hydrocoop in 2015 as « Innovative Associated Spillways » can leverage the strength of each system. More than 30 years after its first application, the returns of experience of the Hydroplus Fusegate® system applications on more than 80 dams in 25 different countries have confirmed their reliability in terms of sequentially overturning on the downstream side for the correct design flood. With their high discharge capacity at low head, PK-Weirs optimize the use of the flood storage volume by decreasing the peak of the downstream flood. As shown in the presented study case, the combination of these two innovative passive dispositions provides robust solutions for ensuring reliable safety during common and extreme, even unpredicted, floods.
