Abstract:
Assessing uncertainties is done systematically in almost all hard sciences research
fields, and in more and more numerous engineering domains. In the field of urban
water systems, this is still not a systematic and common practice. Therefore, one of
the aims of PREPARED is to promote, to contribute and to exemplify how to
systematically evaluate uncertainties in urban water systems.
Assessing uncertainties is necessary:
- to better quantify and to improve the quality of measurements;
- to better contribute in modelling, by accounting for uncertainties in model
structures, inputs, parameters and outputs;
- to better help in decision making.
This PREPARED deliverable includes:
- an introduction to the two internationally recognized standards for assessment of
measurement uncertainties (GUM Law of Propagation of uncertainties and the
Monte Carlo method);
- three examples of application, with various levels of complexity, showing in detail
how to apply the above methods for uncertainty assessment. The examples deal
with sewer systems, but they can be easily transposed to other components of
urban water systems.
- references to additional documents.
