1. 2nd IMPACT Workshop
Mo i Rana, Norway
12/13th Septemper 2002
Life after RESCDAM?
Application and future developments for emergency planning in Finland
Mikko Huokuna, Finnish Environment Institute

2. Development of Rescue Actions Based on
RESCDAM
Development of Rescue Actions Based on
Dam-Break Flood Analysis
Coordinator:
Finnish Environment Institute

3. Partners: ENEL Research, Hydraulic and Structural Centre (Milan)
EDF Electricite de France, National Hydraulic Laboratory (Paris)
Helsinki University of Technology
Emergency Services College (Kuopio)
Seinäjoki Rescue Centre
West Finland Regional Environment Centre

4. emergency action planning for dams
The pilot project of RESCDAM was
the embankment dam of the Kyrkösjärvi
reservoir located in Seinäjoki in Western Finland.
The main purpose of the RESCDAM project
was to develop
emergency action planning for dams

5. The project work was divided into three sub-projects:
Risk Assessment (Analysis)
Dam Break Hazard Analysis
Emergency Action Planning
International Seminar and Workshop was
arranged on October 2-5, 2000 in Seinäjoki

6. Kyrkösjärvi Dam Break Hazard Analysis
Model simulations of the erosion dam-break event
an erosion model developed in Finland
One-dimensional flow simulation
DYX.10 -model (finite difference method)
Two-dimensional flow simulation
Telemac-2d, EDF (Finite Element Method)
FLOOD-2d,ENEL (Finite Volume Method)

7. Kyrkösjärvi Dam Break Hazard Analysis
Assessment of breach-hydrograph has a lot of uncertainties
After sensitivity analyses two breach hydrographs were chosen for flood analyses with 2-d models
HQ1/100 Flood case
MQ Case

8. Three breach locations considered

9. Flood propagation Max depth Max flow velocity Max damage parameter
FLOOD MAPS FOR EMERGENCY ACTION PLANNING
Flood propagation
Max depth
Max flow velocity
Max damage parameter
(flow velocity x depth)

10. Flood maps

11. The use of GIS in analysing calculation results
The damage parameter (velocity x depth) map

12. The locations of the houses from the buildings database

13. The houses effected by the HQ dam breach case

14. The houses for which the damage parameter is >3

15. DEVELOPMENT OF EMERGENCY ACTIONS
Recommendations to update the Finnish dam safety guidelines
Emergency/rescue action plan for the Kyrkösjärvi dam

16. The work to update the dam safety code of practice is going on
AFTER RESCDAM
The work to update the dam safety code of practice is going on
The internet based dam safety information system is under development
Updating of the Emergency Action Plans for the P-dams is going on
Some research: Effect of freezing and melting on embankment stability

17. Updating of the dam safety code of practice
No major changes
Most changes to:
safety monitoring and inspections
dam break hazard analysis (presentation of the results)
Emergency action planning and advance information

18. Internet based dam safety information system
information on about 450 dams (now for a. 300 dams)
information on P-dams (39) is going to include
general information of the dam
monitoring information
documents, measurements
emergency action plan
Dam-break hazard analyses (new analyses will be documented in a certain way to be easily available for more analyses)
Flood maps

19. Work to update Emergency action plans for P- Dams is going on
There are 39 P-Dams in Finland
A dam is classified as a P-dam if in an event of an accident, it may:
-endanger human life or healthy
-seriously endanger the environment or property

20. Work to update Emergency action plans for P- Dams is going on
All the P-dams in Finland have some kind of emergency action plan but many of the plans should be updated and revised
People living in the risk area of the dam have to be informed about the risk (in advance) and about the emergency action plan
Training of emergency action
The plans have to be tested in training

21. Emergency action training for Kyrkösjärvi dam
Organized by Seinäjoki Rescue Centre and West Finland Regional Environment Centre, September
