| Zusammenfassung |
| In the Lombardy Region, as in many other contexts all over the world, hazard maps
do not have a precise legislative confirmation. Despite this, they are
necessary to support several institutional activities, and among these, local
urban planning. An approach to hazard analysis and mapping
that fits the Lombardy Region legislative framework is presented here that introduces a level
of experimental modelling, making use of SOBEK 1-D–2-D as a tool for
hydrodynamic simulations. A stretch of 17 km of the Adda river in Valtellina
has been modelled, referring to twelve scenarios characterised by different
temporal probabilities, and comprising the main sources of uncertainty.
The results were compared with available local hydraulic studies, and combined to
obtain two complementary flood hazard maps which could usefully support urban
planning. Advantages and drawbacks of this modelling approach, together with
considerations related to flood hazard mapping are discussed. |
