Assessing uncertainty in stormwater quality modelling

Assessing the Quality of Business Process Modelling

The conceptual modelling of business processes is becoming popular. The number of techniques and tools is growing fast. At the same time, an appropriate framework for understanding the quality of these modelling techniques is lacking. In this paper we report upon the development of a framework for understanding the quality of business process modelling techniques, called the QME framework. The ...

Analysis of uncertainty in flow and water quality from a stormwater model

Uncertainty is intrinsic to all monitoring programs and all models. It cannot realistically be eliminated, but it is necessary to understand the sources of uncertainty, and their consequences on models and decisions. The aim of this paper is to evaluate uncertainty in a flow and water quality stormwater model, due to the model parameters and the availability of data for calibration and validati...

Stormwater Chemistry and Water Quality

Components of road surface degradation are common constituents of urban runoff. Studies conducted in Europe have indicated that as much as 0.05-0. 10 inch of pavement surface is worn away from the roadway each year. The largest component of street pavement is the aggregate material itself, with additional smaller quantities originating from the asphalt binder, fillers and substances applied to ...

Uncertainty and risk in water quality modelling and management

The case is presented for increasing attention to the evaluation of uncertainty in water quality modelling practice, and for this evaluation to be extended to risk management applications. A framework for risk-based modelling of water quality is outlined and presented as a potentially valuable component of a broader risk assessment methodology. Technical considerations for the successful implem...
