Flood management

1. The EU Floods directive
-Implementation in Sweden

2. National implementation work
The Floods Directive is implemented in Sweden
through a regulation on flood risk (SFS 2009:956).
Swedish Civil Contingencies Agency (MSB) is the
responsible authority and carry out the work in close
cooperation with the county. The work is carried out
in three steps during the years 2009-2015.

3. National implementation work
Step 1 involves a nationwide preliminary flood risk
assessment to be carried out. With this assessment,
the geographical areas with significant flood risk are
identified.
Step 2 means that for those areas where significant
flood risk exists, two types of maps are prepared.
Flood hazard maps (2a) and flood risk maps of the
areas at risk (2b).
Step 3 involves the development of Flood risk
management plans.

Directive
Process

5. Step 1
In step 1 analysis of flood risk was
carried out in Sweden. The
conclusion is that 18 locations have
a significant flood risk. These
locations have been identified
based on MSBs flood mapping
overview and possible implications
for human health, economic activity,
the environment and the cultural
environment
National implementation work

6. National implementation work
Step 2a
Where risks of flood damage exist, MSB must by
2013 develop flood hazard maps for such areas.
The flood hazard maps will show the flooded areas
for four different flows; 50-year flow, 100-year-flow,
200-year flow and a calculated maximum flow.
In addition, the maps will also show the depth and it
is also possible to obtain information on the velocity.

7. Example of flood hazard map
Flood hazard maps of the
18 affected towns will be
developed with similar detail,
but with the new national
elevation database as a
basis.

8. National implementation work
Step 2b
During 2013, flood risk maps for the 18 identified
towns should be developed by the five county
administration boards.
The flood risk maps should include information such
as number of affected persons, land use, protected
areas and hazards that can cause contamination at
a flooding.
Guidelines and guidance for the development of the
flood risk maps are developed by MSB.

9. National implementation work
Step 3
The flood risk management plans are to include
measures to reduce the probability of flooding and
its potential consequences.
They will address all phases of the flood risk
management cycle but focus particularly on
prevention, protection and preparedness

10. 2010 - Inventory of historic floods in each county,
coordinated by district. The county administrative boards
supplied documentation.
2011 – Submission for comments concerning identified
areas of special risk for flood risk. The county
administrative boards commented.
2012 - Designation of areas with special risk for flood risk
(Step 1). MSB.
2013 - Flood hazard maps (Step 2a). MSB with
consultant.
2013 - Guidance for the preparation of risk maps. MSB.
2013 - Risk maps (Step 2b). Coordinated by district,
different organization (different units, different
approaches) but discussions nationally in county
administrative board network.
2014/2015 - Risk Management Plans (Step 3)

11. National implementation work
These steps need to be reviewed every 6 years in a
cycle coordinated and synchronised with the Water
Framework Directive (WFD) implementation cycle.

12. Regional implementation work
The County Administrative Board of Norrbotten has
since 2009 coordinated the work on flood regulation
in Norrbotten and the Gulf of Bothnia water district.

13. Regional implementation work
• The County Administrative Board of Norrbotten is
waiting for the flood hazard maps from MSB for
Vännasby, Älvsbyn and Haparanda – Expected in
May
• Starting up coordination with Västerbotten and
Finland (a.s.a.p.) - mutual exchange of information.
• Preparing risk maps - In a first step, the flood risk
area upstream and downstream will be identified,
e.g. to calculate the population that may be affected.
Work on risk maps will be completed by December 22
2013th

14. Thank you!

15. Links between WFD and Floods Directive
• Similar planning and timetables
• Target Directives
A) Defined
B) Criteria for implementation
• Similar geographical areas
• Measures need to be effective
• Consultation and participation
