Int. Conference on ‘Developments in urban drainage modelling’ location:London date:21-24 Sept 1998
The main advantages of the probabilistic modelling of urban drainage systems are the possibility of quantification and efficient reduction of the risk of 'wrong' management decisions or engineering designs, as well as the less biased mathematical modelling. Such probabilistic modelling achieves quantification of the uncertainty in the field of model-output. In the modelling of sewer system overflow emissions, a lot of uncertainties are involved: uncertainties about the spatial rainfall-input, model simplifications of the sewer system and runoff catchment, and biases and uncertainties about the model parameters.
