This paper describes a mathematical sediment transport model for sewers. The model consists of a full hydrodynamic description running in parallel with a morphological model. Four different sediment transport formulations have been implemented in the model. Fredsøe's method for the calculation of the resistance from bed forms is compared to experiments carried out at Chalmers Technical University, Sweden. The model can be used as a tool for the analysis of sewer systems with sediment deposits. The model is being developed as part of a study being carried out at the University of Aalborg, Denmark and VBB-VIAK, Sweden.

The present paper presents an application of MOUSE ST, a general deterministic sediment transport model for sewer systems. MOUSE ST is used to predict the locations subjected to sedimentation in the sewer system of Ljubljana, Slovenia. The prediction is made by means of a sediment transport model with a movable bed. This model is run in parallel with the hydrodynamic MOUSE model. The results, in terms of locations with sediment deposits, are compared with field data from the sewer system in Ljubljana. Further, the model is used to predict the effect of the removal of the sediment deposits on the combined sewer overflows.

Modelling Approaches

A study has been carried out with the objectives of describing the effect of sediment deposits on the hydraulic capacity of sewer systems and to investigate the sediment transport in sewer systems. A result of the study is a mathematical model MOUSE ST which describes sediment transport in sewers. This paper discusses the applicability and the limitations of various modelling approaches and sediment transport formulations in MOUSE ST. Further, the paper presents a simple application of MOUSE ST to the Rya catchment in Gothenburg, Sweden.
