| Zusammenfassung |
| Uncertainty in conceptual model structure and in environmental data is of
essential interest when dealing with uncertainty in water resources
management. To make quantification of uncertainty possible is it necessary
to identify and characterise the uncertainty in geological and
hydrogeological data. This paper discusses a range of available techniques
to describe the uncertainty related to geological model structure and scale
of support. Literature examples on uncertainty in hydrogeological variables
such as saturated hydraulic conductivity, specific yield, specific storage,
effective porosity and dispersivity are given. Field data usually have a
spatial and temporal scale of support that is different from the one on
which numerical models for water resources management operate. Uncertainty
in hydrogeological data variables is characterised and assessed within the
methodological framework of the HarmoniRiB classification. |
