Modelling of sedimentation and remobilization in in-line storage sewers for stormwater treatment

摘要

A special arrangement of combined sewer overflow tank's is the in-line storage fewer with downstream discharge (ISS-down). this layout has the advantage that, besides the sewer system, no other structures are required for stormwater treatment. The verification of the efficiency with respect to the processes of sedimentation and remobilization of sediment within the in-line storage sewer with downstream discharge is carried out in a combination of a field and, a pilot plant study, The model study was carried outusing a pilot,plant model scaled 1: 13. The following is intended to present some results of the pilot plant study and the mathematical empirical modelling of the sedimentation and remobilization process.
