Hydro dam inspections using a rotating head sonar provide accurate information about plunge pools and sink holes. AquaCoustic uses a range of technologies to survey dams and reservoirs, including scanning sonar, video, multibeam and rotating head sonar. AquaCoustic has collaborated with a leading sonar manufacturer in the development of a specialized profiling sonar system. This rotating head sonar system offers distinct advantages over multi-beam sonar, providing extremely accurate visualization and measurement of underwater features, of up to 2 mm resolution at close range.

Use rotating head sonar surveys to locate bottom and sub-bottom river crossing hazards before disaster occurs. Pipeline crossings and other river bottom features can present hazards in waterway systems. Over the course of time, or because of floods, poor installation, tide action, river traffic, or unusual conditions, these features can change location with respect to the bottom – with potentially disastrous results. AquaCoustic has found situations where, for example, high pressure gas pipelines have become suspended above the river bottom presenting a major hazard to shipping and the surrounding area. The US Government mandates that pipelines crossing inland navigable waterways in excess of 100 ft in width maintain a cover of 48 inches, and are to be inspected once every five years. Visual inspections are not adequate for this purpose.

Surveys of port facilities using a rotating head profiling sonar provide accurate ships’ berth depth measurements. As commerce increases, port authorities and ship operators require accurate bathymetric information in order to maximize the use of port facilities and the vessels that use them. Knowing ships’ berths profiles and depths are critical in order to accommodate today’s vessels and new hull designs. Ramp and fairway depths must also be accurately known. In addition, ship’s thrusters, dredging operations, and the normal scouring and sedimentation action of tides and rivers can rapidly change underwater conditions.
