Flash Flood Management at the Local Level To take control over the hazard Roman Konieczny, Office for Collaboration with Local Government Institute of Metorology and Water Management Krakow. Poland
Office for Collaboration with Local Government, IMGW
The Institute of Meteorology and Water Management (IMGW) is the research-and-development unit which runs the national hydrology and meteorology service. The Institute gathers and processes hydro-meteorological data, on the basis of which it also prepares warnings concerning threatening natural events, in the form of information, communications and hydrological and meteorological prediction.
Office for Collaboration with Local Government – the unit of the Institute focus on cooperation with local communities. The office was involved in realization of many national and international projects in the field of flood management.

LOCAL FLOOD WARNING SYSTEM Case: Kłodzko Valley Did they reach you on time? Did you receive any warning s in 1997? Office for Collaboration with Local Government, IMGW Kraków, Poland
Local Flood Warning System OSIRIS Project (V FP) Tools for county crisis management center: Software aiding local center in assessing flood risk and possible consequences of risk Notification system mass telephone notification system to inhabitants (800 persons/hour) Educational program – cooperation with schools, gminas, journalists, NGO. Klodzk County: floods in 1997 / 1998, total losses 87 / 28 mln PLN, fatalities 13 / 8. District of Klodzko built local flood monitoring system (40 rain and water gauges) Office for Collaboration with Local Government, IMGW Kraków, Poland
Żywiec District Brzesko Commune Local Flood Warning Systems in Poland Mielec District Jasło District Wroclaw City Kędzierzyn-Kożle City Kłodzko Dist. Nowa Ruda Commune Świdnica District Tarnów City Kraków City Staszów District
Civic flood warning system – Nowa Ruda Nowa Ruda Advantages public involvement simple and cheap solution Disadvantages lack of rain observation unreliability of SMS communication
How the system works
Automatic measurement station notifies operator that pre-determined water level has been exceeded (SMS)
Operator „awakens” volunteers, they start to observe water levels along the river and send it (SMS) to database
The operator, based on analysis of the received data, cloud observation and other information from the Internet makes the decision whether to warn inhabitants
A computer program distributes warnings via SMS, based on the addresses collected in the database
Aims of system t o ‘awaken’ crisis intervention forces to warn inhabitants Office for Collaboration with Local Government, IMGW Kraków, Poland
Share collected knowledge and experience with others.
Basic assumptions: Cooperation of Institute of Meteorology and Water Management and National Water Management Board Pilot in nationwide programme addressed to self-government, schools and parents. Training for teachers Uszwica river catchment keep the people away from the flood Be familiar with flood (community preparedness)
School competition Task 1 – historical floods Task 2 – family evacuation plans Task 3 – sharing knowledge Watchwords of education 1. Flood is inevitable (remember that you are at threat) 2. Level of your flood losses depends on you (be prepared) 3. You are not alone (keep contact with crisis centre) Office for Collaboration with Local Government, IMGW Kraków, Poland

P REPERATioN OF LOCAL FLOOD MITIGATION PLANS Residents believe that only structural measures are able to help them. Reservoirs planned for upper Nysa Kłodzka reduce 1% flood in Gorzanów by 0,3 – 0,4 m. Office for Collaboration with Local Government, IMGW Kraków, Poland Did you know that your house is in an area at risk? Did you take protection measures during the flood?
Pilot site Gorzanów village Gorzanów Gorzanów small historical village on the river Nysa Kłodzka Area: 1598 hectares Inhabitants: 1003 Last floods: 1938, 1997 Lead time: 3 hours Flood damages Houshold unit: 81 Inhabiotants evacuated: 300 Total losess: 3.3 mln EU Local Flood Mitigation Plan Experience Office for Collaboration with Local Government, IMGW Kraków, Poland

Flash flood hazard mitigation requires the involvement of local communities. The flood process in such cases is of such short duration that inhabitants at risk should be able to take independent action to mitigate hazards to life and property.
This requires action to be taken in the area of:
Building a system for early warning of inhabitants
Preparation of flood mitigation plans
Knowledge of the hazard, its character and methods of behavior during a flood.
This requires support from the administration. We suggest that the tasks of these institutions should include: early meteorological warning, designation of areas at risk for flash flooding, preparation of handbooks and useful information, conducting of training, support in building local plans.
