A method of determining the concentration of dredger spoil in a suspension of dredger spoil and water flowing through horizontal pipe 17 comprises determining the difference in pressure between at least two different levels 11, 12 in the pipe from which the concentration may be determined. In one embodiment the pipe is provided with a construction 18 to ensure that there is no settlement in the base of the pipe at the point at which the measurement is taken.
