Hazard Mapping
Canton authority for river course management (DFSB) provide
support, financial incentives and expertise to the communes
so that the canton's hazard mapping exercise can be
completed.
DFSB are responsible for coordinating the
communes and the engineering offices in
the production of these hazard maps, and
underwriting their validity and publishing
them (Art. 3 (1)) since the results of
hazard mapping must be transposed into
spatial plans (according to FPA). The local
authorities are responsible for completing
the mapping exercise and implementing
its fi ndings.
Cellule scientifique de crise (CERISE)
The scientific cell for crises is composed of representatives from
the cantonal office for forests and landscape, the DFSB/
SRCE and the service for hydropower (service des forces
hydrauliques - SFH) in order to aid the authorities in their
decision making ability during flood and avalanche hazards.
Communes are legally required to ensure the safety
requirements, and the canton natural hazards division
subsidises their work.
CERISE is split into summer and winter
competencies and comprises canton
geologists, river work engineers and the
natural hazards division and is linked to
MeteoSchweiz. Of the 23 regions in the
Valais, so far, there are 3 regions where
the process already functions. In heavy
precipitation events, they need to measure
the rainfall quantity in certain streams, but
up until now, they have not done this.
