Abstract

There are a variety of multi-transducer systems (see Figure 1) for clearing shallow and deep-draft navigation projects. These systems are designed to provide 100% bottom coverage of a given project site and are particularly useful in searching for and supporting clearance of hazards to navigation. They are also used for performing dredge measurement and payment surveys since their full coverage capabilities provide more accurate quantity computations. After-dredge surveys performed with multitransducer systems are used for certifying channel grade clearance. Some hydrographic survey companies use multi-transducer systems for routine project condition surveys because they are useful in locating channel obstructions. Multi-transducer systems are mainly used on shallow draft and inland navigation projects. Their use on deep draft projects is declining due to increase reliance on multibeam technology. Since multi-transducer systems are similar in operation to single-beam systems, most of the quality control and quality assurance are applicable to multi-transducer system operations.
