Statistički pokazatelji ukazuju da je najčešći uzrok oštećenja i rušenja mostova djelovanje vode. Učešće toga uzroka je oko 50 %. U uvjetima kada mostovi s dijelom svoje konstrukcije zadiru u protočni profil aluvijalnih vodotoka u interakciji s vodom izazivaju lokalne promjene na koritu.

UNDERWATER INSPECTION - THE STATE OF ART
1992Abstract Most of the oil produced in Brazil comes from maritime oil fields, where steel structures are the most important piece of the whole system. This work intends to show the state-of-art of underwater inspection and its interation with the key-element of the inspection process: the diver inspector.
