| Short description: |
The exfiltration of waste water from sewer systems in urban areas causes a deterioration of soil
and possibly groundwater quality. Beside the simulation of transport and degradation processes in
the unsaturated zone and in the aquifer the analysis of the potential impact requires the estimation
of quantity and temporal variation of waste water exfiltration. Exfiltration can be assessed by the
application of the leakage model. The hydrological approach was originally developed to simulate
the interactions between groundwater and surface water, it was adapted to allow for modelling of
interactions between groundwater and sewer system. In order to approximate the exfiltration
specific model parameters infiltration specific parameters were used as a basis. Scenario analysis
of the exfiltration in the City of Dresden from 1997 to 1999 and during the flood event in August
2002 shows the variation and the extent of exfiltration rates.
