ABSTRACT:
Dredging apparatus (10) is provided with a flow conduit (18), a first pump (28), a second pump (30), and two valves (34, 44). The flow conduit (18) comprises a first leg (20) extending downwardly to a lower portion (22) and a second leg (24) extending upwardly from the lower portion (22). A fluidizing nozzle (32) is carried by the first leg (20). An intake aperture (26) is provided on the lower portion (22) and is directed downwardly. The dredging apparatus (10) may be used to dredge up material when the material is in a water suspension (48), and to probe through material by scattering material. The valves (34, 44) are operated to switch the apparatus between various modes of operation and to increase the effectiveness of the apparatus.
