This paper shows dredging using HSRS (Hydro-Suction sediment Removal Systems) which is one of countermeasures for removable sedimentation in a dam reservoir. Since HSRS can also use power other than water head, it is the technology in which expansion of scopes, such as not only dam reservoirs but river channel, a seashore region, etc., is expectable.

This paper is examined about the function of pipe-line sand transportation. Therefore, it reexamined about experiment data from a viewpoint of sediment discharge and flow state of sediment in a pipe-line. Consequently, the fundamental knowledge about sediment transportation by pipe-line was acquired.
