by level of the analytical process
• Paradigm level: e.g. long term evolution in societal value
systems and prioritization structures
• scenario choices; delineation; (model type choice)
• Conceptual level: understanding of the causal structure
• Model (type) choice; model structure; data sources/needs
• Model level: sufficiently adequate representation of the causal
structure and orders

on the surface type and cloud conditions. Compared with shortwave radiation, longwave
radiation fluxes are less dependent on the presence or absence of snow on the ground, and more
on cloud conditions. Relative net longwave radiation losses vary between a minimum of 5%
over the ocean with overcast conditions, and a maximum of 36% over the glaciers with clear
skies. Sensible heat fluxes remove between 2% (cloud

& Jasper, 2007).
Information on land use, soil type, elevation and other general properties of the watershed
are given in static distributed grids while a number of parameters describing specific
processes are adjusted to the properties of each watershed by comparison of modelled and
measured discharge series.

is taken into account, and
consequently the estimated incremental impacts tend to be near the upper bound. If over the
course of time (i.e. as climate change proceeds) road users and road administrations get convinced
that the frequency of some adverse events has increased, adaptation will start to occur, e.g. by
using another type of asphalt, favoring cars with more intelligent braking
