Fusegate systems are an innovative solution for dam safety upgrades, flood protection and water resources efficiency whereby a series of fusegate modules act as a waterproof wall. During flood events, when the dam is full water flows over the crest of the fusegate modules, which acts like an ungated spillway. As the flood water levels rise, the fusegate modules sequentially tip, one after the other. The tipping threshold of each module is set precisely by the height adjustment of their inlet well, to ensure the units overturn progressively in order to compensate for the effect of exceptional flood levels.
