Detecting method of the type of submerged materials and scouring

Abstract

An assessment of the detection methods of immersed materials was carried out by the CNR Test Control Measurement laboratory from 2000 to 2003 The preliminary feasibility study has shown that the side-scan sonar was the most effective detection method. Therefore an extended survey has been undertaken using this technology, on specific and linear sample works, in collaboration with IOTA Company, specialized in acoustic detection. The advantages of this type of investigation concern the detection of scouring of works with diffi cult access, for its high effectiveness on linear works, and for the material characterization of the embankments protection and of the river bed.
