Abstract: This paper describes the latest measuring techniques used for cohesive sediment research at the University of Liverpool, United Kingdom, and in particular the application of medical diagnostic ultrasound technology to the laboratory investigation of fluid mud. Fluid mud has been defined as a dense suspension containing a concentration of flocculated mud which is high enough to significantly change the physical properties of the mud/water mixture compared to those of clear water with the same temperature and salinity!. Fluid mud is formed under a variety of conditions and may flow under the influence of gravity and hydrostatic forces and settle in navigation channels and berths, causing significant rates of siltation over and above those due to settlement directly from suspension. Failure to take account of fluid mud can lead to increased hazards both in navigation and in environmental factors resulting from the inappropriate design and maintenance of maritime works.
