3 Legislation in Finland Flood directive (2007/60/EY) Act for flood risk management (620/2010) Decree on flood risk management (659/2010) 3

4 Flood directive implementation and the time table of first round Preliminary flood risk assessment Flood hazard maps and flood risk maps Flood risk management plans

5 Preliminary flood risk assessment Mapping of flood risk areas by river basins One or more/ none significant flood risk areas Hearing (3 months) ELY-centres proposal for significant flood risk areas Proposal is delivered to Ministry of agriculture and forestry (MMM) MMM confirms the significant flood risk areas Time limit of the directive The first review Review and update every 6 th year MMM sets up a Flood group (regional councils gather the participants to the group) to river basin, where significant flood risk areas exist 5

6 Flood hazard maps and flood risk maps Preparing flood hazard maps and flood risk maps for significant flood risk areas Time limit of the directive The first review High probability of flood (1/50a = 2%) Medium probability of flood (1/100a = 1%) Very low probability Review and update every 6 th year 6

7 Flood risk management plans Preparing the flood risk management plans for river basins where significant flood risk area(s) exist ELY-centre prepares a proposal for flood risk management plan Processing of the plan in Flood group Hearing (6 months) ELY-centre finishes the proposal for flood risk management plan and delivers the management plan to MMM after it has been processed in Flood group Time limit of directive First review Review and update every 6 th year 7

8 Competent authorities Ministry of agriculture and forestry Guides and follows the enforcement of the law and takes care of reporting to the commission Confirms the significant flood risk areas and accepts the management plans, sets up the Flood group Ministries of the Interior, Environment, Transports and Communications Participate together with ministry of agriculture and forestry to the guidance and monitoring of the implementation of the law for flood risk management Centers of Economy, Transport and Environment Are mainly responsible for the planning of flood risk management Participate to the Flood group Finnish Environmental Institute, Finnish Meteorological Institute Give expert help to ELY-centres Other assignments considering flood risk management given by Ministry of agriculture and forestry Regional councils Gather the Flood group and participate to the Flood group Municipalities Are responsible for flood risk management related to storm water floods Participate to the Flood group Area s rescue service and other authorities Participate to the Flood group 8

9 Preliminary flood risk assessment (PFRA) in Lapland Three River basin districts, in which all together nine River basins and northern coastal area of Bothnian Bay 10 PFRA reports and one separate report for sea flood ELY-centre for Lapland, Timo Alaraudanjoki and Niina Karjalainen 9

10 Content of PFRA report 1. Background 2. Description of the river basin 3. Floods in history 4. Possible floods in future and flood risks 5. Using GIS-data in flood risk estimation 6. Flood risk areas 7. Suggestions for significant flood risk areas 10

11 Content of PFRA report 1. Background chapter describes in general how flood directive has been implemented in Finland 2. Description of the river basin In this chapter information about river basin are described Hydrology Population and land use Land use planning Protected areas and cultural heritage Flood protection and the use of the river basin 11

12 Content of PFRA report 3. Floods in history Observed floods o Information about floods that have caused major damages 4. Possible floods in future and flood risks Effect of climate change on floods 5. Using GIS-data in flood risk estimation In this chapter the modelling made by Finnish Environment Institute is described. 12

13 Content of PFRA report 6. Flood risk areas In this chapter bases for significant flood risk areas are described Empirical knowledge and earlier reports o Already known areas that have had major problems with flooding Flood risk to human health and security o Areas where inhabitants live, areas where are buildings that are hard to evacuate (hospitals, old people s homes, day-care centres, schools etc.) 13

14 Content of PFRA report Flood risk to essential services for community o Areas where are food industry or pharmaceutical industry o Electricity and drinking water distribution networks and services o Road and railroad networks Flood risk to environment and cultural heritage o Contaminated lands, waste disposal sites, waste water treatment plants o Cultural heritage sites that may suffer unrepaired damages if flooded Threat of flood caused by water structures o Dams (dam breaks) 14

15 Content of PFRA report 7. Suggestions for significant flood risk areas In this chapter the possible significant flood risk areas are proposed by basis described in chapter 6. If no significant flood risk areas are proposed, also bases for not to propose any areas are described here. 15
