The ability of Sustainable Urban Drainage Systems (SUDS) to mitigate Combined Sewer Overflows (CSO) is often studied through a catchment-scale modeling approach. Simulation accuracy depends on field data such as catchment and sub-catchment boundaries, and sewer system characteristics. The present study proposes a methodology for (sub-)catchment delineation depending on the available geographic information data. Four scenarios with increasing complexity of input data are proposed and tested in different urban catchments, followed by hydrological modeling to compare flow dynamics. Current results show a better estimation of total runoff volume when topography is available, even if the sewer network plans are unknown

Development of BANPOL model for water quality predictions in urban sewer system


Chungnam National University, Korea, Republic of (South Korea)

Most of hydrological models do not consider sewer effect on transport and fate of water and pollutants, respectively, and thus they have limited applicability in urban area with complicated sewer system. The BANPOL model was developed to strengthen water quality modelling capacity of SWMM especially for pervious area and also in the sewer or channel. The model also can provide boundary condition for dynamic surface water quality model such as EFDC while original SWMM only provides information on independent water quality variables. The model was successfully calibrated for flow rate and water quality in an urban stream

I was told by Mr. Konig to upload a .pdf version of my abstract. Why is there no option to do that? Also, the website explains that two page abstracts will be accepted. the 100 words allowed here is not two pages.

Better understanding in-sewer processes with on-site continuous mass spectrometric analysis of sewer gases

We performed continuous measurements of noble gases in sewers for the first time used a novel portable mass spectrometer. A case study regarding using noble gases as tracers to estimate groundwater infiltration showed the potentials of using miniRuedi on urban drainage tracing studies. Although the technology looks very promising in general, infiltration assessment is impacted by unknown boundary conditions, such as gas dilution in the headspace/ventilation.
