Gross solid transport in sewers
MetadataShow full item record
Gross solid transport in sewers has been studied in the laboratory, by theoretical analysis, and in the field. A simplified model is proposed that can be run as an extension of existing sewer software packages (for example HydroWorks) in order to simulate the advection and deposition of solids within an entire sewer system. The model has potential applications to the engineered improvement of sewer infrastructure (including storage facilities and screening systems) and to the simulation of first flush effects and of the impact of future changes in catchment flows. A technique for tracing the physical progress of specific solids in a sewer has been developed, and has been used within an actual length in order to test the model.
