Transcript of AUTOMATED MODEL FOR IMPLEMENTATION OF UNIFIED CRITERIA FOR FLOOD RISK CLASSIFICATION IN BULGARIA
SIXTH BULGARIAN AUSTRIAN SEMINAR‐
Automated model for implementation of unified criteria for flood risk classification in Bulgaria
Lyubomir Filipov, Antoniya Gerdzheva, Adelina Naydenova
SIXTH BULGARIAN AUSTRIAN SEMINAR‐Practice and Research in Flood Risk Management
Sofia, 7-8 November 2013
Introduction
Floods...
Most common disaster worldwide - 139
million people affected by disasters in 2012
(source: World Disasters Report 2013);
Damages to people lives, properties and to
the environment;
A higher flood risk is expected in the future
decades;
Proper measures could limit their number and
impact;

Main goals and tasks
Aim of the report – presentation of an automated model for flood
risk assessment in Bulgaria;
Main tasks:
Review of the current European acquis and the equivalent legislation in Bulgaria;
An overview of the geographic information system (GIS) functionality
for flood risk determination;
An overview of the possibilities for modeling and dissemination of
data.
European acquis and equivalent legislation in Bulgaria
Directive 2007/60/EC
The Directive and the Bulgaria legislation
Methodology for detemination of areas with
potential significant flood risk (APSFR)Project: „Assisting River Basin Directorate with center Plovdiv
Town in Defining Areas of Potential Significant Flood Risk (APSFR) in East Aegean Sea River Basin Directorate”
Study area
East Aegean River Basin District (EARBD) with center Plovdiv
one of the 4 river basin districts within the territory of the Republic of Bulgaria;
situated in the central part of southern Bulgaria;area of 35 227 km2;
APSFR determination process and the place of the automated model
Analysis of the available data from EASRBD;Development of a geo-database with information for the
significant past and potential future flood events;Determination of APSFRs;
Application of unified criteria for flood risk classification for determination of PAPSFRs;
Determination of the final APSFRs after detailing its borders;Development of a final geo-database;Presentation of the final data in a table, necessary for the
preparation of a report;Preparation of maps of each APSFR;
Unified criteria for classification of the risk
According to the methodology – 4 categories:
Human health – Affected inhabitants (victims); Affected critical
infrastructure elements or affected buildings of public significance
(hospitals, schools, etc.); Wells and pumping stations for public drinking
water supply.
Economic activity – Motorways, class І and ІІ, railways, bridges,
airports, transmission grids and other linear infrastructure; Affected
agricultural areas; Summarized economic value of damages (for past
floods);
Unified criteria for classification of the risk
According to the methodology – 4 categories:
Environment - Sewage systems of settlements – discharge of
municipal sewerage systems or urban waste water treatment plants; Affected protected areas: drinking water, areas under the Protected
Areas Act, Natura 2000; Industrial Pollution Control (IPPC) and prevention of chemical accidents SEVESO (Council
Directive 96/82/EC) enterprises, Pollutant release and transfer registers (PRTR) of EEA, MoEW;
Cultural heritage - Cultural and historical monuments of UNESCO and
such of national significance;
Work procedures for the model development
Maps and results
Other applications of GIS for flood risk management
GIS and flood risk management:
- data integration from variety of sources;
- rich analytical functionality;
- rich visualization of results;
Other applications of GIS for flood risk management
Application of collaborative GIS platform:
- Taking into consideration the feedback of the public for the decision making process;
- Improving decision by incorporating local knowledge into existing knowledge base;- Getting legitimacy for decisions – not to present or impose decisions;
Example of Ushahidi collaborative GIS platform with options to gather data from web, mobile apps, twitter, sms, email or phone.
Conclusions
Advantages of the model:
● Reduces the possibilities of errors;
● Makes the process of determination of APSFR faster and easier;
● Applicable for all river basin districts;
● Opportunities for further dissemination of the results and other
relative to floods data trough the usage of collaborative GIS
platforms.
